The points of sowing propagation of the crocus sativus

  Many flower friends are very like Eustoma, but do not know how to propagate Eustoma. In fact, the eustoma is a perennial plant, usually with the method of seed propagation, if you successfully seed propagation of the eustoma, then as long as the maintenance of good, the eustoma can bloom every year. I will give you a brief introduction to the sowing propagation method of crocus, if you like, you can learn together.

Eustoma

  1, first of all, prepare a good seedling soil or seedling block, in order to facilitate some, you can try to use a separate seedling pot seed, so that germination can avoid germination time is not the same, and the phenomenon of futility. Then fill the soil with a spray bottle after spraying, and then sit underneath in a larger water basin, so that the soil can make the whole all wet.

  2, with the seeds of friends should be careful to open the bag, because the seeds of the crocus is particularly small, like dust, even gasping for breath seems to be blown away, so must be careful, it is best to have something underneath the next, laying a layer of white paper, so that even if it is accidentally dropped, not afraid to find it. Then there is a toothpick slightly sticky water, a little bit on the seeds, it is stuck to the toothpick, and then planted in the nursery pot is much more convenient. It should be noted that it is not necessary to cover the seeds with soil. Just put them directly on the surface of the soil.

  3, put the seeds above if there is a cover can be covered with moisture, if there is no cover, you can cover a layer of plastic wrap used at home. This can maintain humidity. Every day to open the air can be. You can also take a particularly fine spray bottle spray water every day, if you feel bad to grasp, you can sit directly in the water basin to maintain humidity. But always remember, don’t leave it in 24/7, just spray it gently every day or sit in it for a while. I personally think that the seeds also need to breathe, soak for a long time the seeds will be soaked, but not easy to germinate. Generally planted 15-20 days or so will germinate, later there are 30 days hair. Pros must have patience, do not give up on them, in the absence of germination before the humidity has to be maintained.

  4, after germination, no need to cover the lid, you can bask in the sun, but do not expose to the sun, because just sprouting seedlings are very fragile, a sun is very easy to dry it dead. At this time also do not need to be placed in the water basin every day, see a little dry point and then put can, just sprouted try to gently spray, because the seedlings are very small, a hard spray will fall.

  5, when the leaves grow up some can be planted, the orange blossom is a taproot system, it is best to move less, because every time you move back will be more or less some damage, so move as little as possible. To remember to put some bottom fertiliser in the pot, which can save a lot of trouble. I planted eustoma, from last May planting, until this year’s flowering, except for the bottom of the fertiliser, other than the rest of the fertilizer, only after the flowering to supplement the other fertilizer. So I personally think that the bottom fertiliser is very important, that is, simple and convenient, after planting to see almost dry and then water, do not have to water hard, I think the more you pay attention to it, the faster it dies, my family’s eustoma, basically did not care much about it, put aside, think of pouring water, watering must be watered through, it can be.

Grafting propagation points of scarlet peony

  

  With its small, colourful plants, the scarlet peony is an excellent indoor potted plant, as it looks very pretty when in bloom. The scarlet peony, topped with a bright red cactus ball, is a good omen of “good luck”, making it an ideal gift for friends and relatives. What should we pay attention to when propagating this popular species?

Crimson Peony

  The scarlet peony is mainly propagated by grafting. Greenhouse cultivation can be carried out all year round, and spring or early summer is the best time for fast healing and high survival rate. Choose a strong and tender rootstock (commonly used as measuring tape (details), or cactus, cactus column, tiger spur, etc.), and flatten the top; choose a robust seed ball with a diameter of about 1㎝ from the mother plant as the scion, peel it off and flatten it with a sterilised sharp blade, put the seed ball close to the incision of the rootstock, with the heart of the ball aligned with the central column of the rootstock, and tie it firmly with a fine thread or a fine rubber band, and make it suitable to be loosened or tightened. At room temperature 25-30 ℃ under the condition of maintenance, 7-10 days to untie, and then maintenance for two weeks, such as the interface is intact, that has been live. General catch two months after the ornamental.

Treatment and Prevention of Common Diseases of Unicorn Palm

  Also known as Kirin’s Horn and Jade Kirin, Kirin’s Palm, which is native to India, is a common foliage plant. It is named so because its stems and leaves are fleshy and look like the unicorn in ancient Chinese legends. Not only can it beautify the environment, it can also absorb formaldehyde and other harmful gases in the air, so it is also a plant with a high breeding rate.

Unicorn Palm

  Firstly, the prevention and treatment of Aspergillus rot disease of Qilin palm

  In the process of breeding the unicorn palm is most likely to suffer from varroa rot disease, the following with you to share with you the unicorn palm varroa rot disease prevention and treatment methods.

  1, the unicorn palm varroa rot symptoms: the first affected stem nodes appear yellow-green to yellow-brown lesions, and then gradually softened and rotted, leaving only the dry cortex or the remnants of the stem pith. The diseased part of the yellow-brown mould, that is, the pathogenic bacterial conidiophores and conidia.

  2, the unicorn palm curculio rot law: mycelium to mycelium in the soil, disease residues and other substrates overwintering, the following spring to produce conidia, spread by airflow, by the wound or through the epidermis direct invasion. Potting soil temperature and humidity is not stable or high temperature and high humidity conditions last a long time easy to develop.

  Pathogen

  Aspergillus alliaceus Thorn et Church, known as onion mould, belongs to the semi-mycorrhizal fungi. Conidiophores filamentous unbranched, size 1500 × 15 (supply), the end of the head-like expansion, the top small peduncle 7 ~ 8 × 2 (supply). Conidium spherical, size 2. 3 ~ 3 supply, yellow. Conidiophore spikes are yellow to brown at first. The nucleus of the fungus is white at the beginning and then turns black, size 1000×500~700 (supply).

  4、Treatment method

  (1) after the onset of the timely removal of disease residues, concentrated deep burial or burned, if necessary, replacement of potting soil or 75% Dakonin (Chlorothalonil) wettable powder 1, fine dry soil 50 to 100 mixed well made of medicinal soil, sprinkled on the surface of the potting soil.

  (2) Spray 50% benomyl wettable powder 1000 times or 40% chlorothalonil suspension 500 times, 50% thiophanate-methyl wettable powder 800 times.

  (3) Apply medical Dakinin ointment on the diseased part to make it effective.

Unicorn Palm

  Diseases and Pests

  There are fewer pests and diseases, but long time in the greenhouse or placed in the place of ventilation is not good, easy to be harmed by the mesothelioma. In winter and spring, you can spray the leaves with water once every 10 days to wash the dust. In addition, the unicorn palm is very sensitive to gas, fumigation is easy to cause defoliation.

  Black spot mould

  Summer and autumn are the peak growing season of the Chinese unicorn palm. It likes the sun, but avoid sun exposure, can be used bamboo curtain shade. Watering should be less than more, grasp the principle of dry and wet. When the temperature is low in winter, watering should be controlled. Once a month, you can apply diluted soya bean cake water or jaggery residue water. The unicorn palm is not hardy, generally moved indoors before the frost in mid-October. Room temperature is maintained above 15 ℃, the leaves do not turn yellow, below 12 ℃ leaves dry off. Room temperature above 6 ℃, the potting soil is dry, the unicorn palm will not freeze, the following year will still produce new leaves. Change the pot once every 1 to 2 years.

  The main causes of black spot mould on Unicorn Palm are over watering, poor nutrition or low temperature. The cause will be determined primarily based on your specific situation.

  Aspergillus rot disease can be said to be a typical disease of the unicorn palm, so you must pay attention to the prevention of unicorn palm in the process of keeping unicorn palm, otherwise it can be said to be very harmful to the health of the unicorn palm. If you want to keep a good unicorn palm, you not only need to pay attention to the prevention of disease and pests, but also pay attention to the usual way of feeding, temperature, fertiliser, soil are the key to keep a good unicorn palm.

Southern flowers north should be how to match the soil

  Most of the northern flower soil alkaline, cactus plants, moon season, chrysanthemums, oleander (details) and other suitable for growth in such soil. And southern plants such as azalea, jasmine, Milan, orchids, drip Guanyin, gardenia, orchids (details), but only in the acidic soil to grow healthy. If these acidic plants with alkaline soil planting then it is difficult to survive. So, how to find the right soil for these acidic flowers and plants in the alkaline soil all over the north? It is up to us to prepare the soil with our own hands using the materials around us.

Gardenia (details)

  After autumn, collect some pine, poplar, elm and other trees of the fallen leaves, into a large container, if there is no suitable container can also use black plastic bags. Then compact the prepared peat soil or garden soil with one layer of leaves and one layer of soil, add appropriate amount of ferrous sulphate and insecticide, and then pour appropriate amount of water on top of it, and the amount of water is good to soak the material. Finally, seal the container and put it in a warm place to ferment, so that after an autumn and winter time, you will have acidic soil to use in the following spring. If you have the conditions, you can dig a hole directly in the yard and bury the leaves and soil and other materials into the soil to ferment, and you can also formulate the acidic soil just as well.

  Alternatively, we can neutralise alkaline soil by soaking it in fertiliser as follows:

  Will usually eat the rest of the apple core, watermelon rind, apple skin soaked in cold water for a few days, so that the fertiliser is slightly acidic, often use this water to water the flowers, you can gradually neutralize the alkaline soil, the growth of acidic flowers is very effective.

How to deal with bloomed daffodils

  After the Spring Festival, daffodils wither away, usually people will throw away the bloomed daffodil bulbs, which is actually a pity. Daffodil is a kind of perennial plant, it relies on bulbs to reproduce, if those bulbs that have bloomed are buried into the soil again, it can continue to grow and reproduce.

Daffodils (Details)

  Choose a windy, sunny, deep soil garden or nursery land, deep ploughing and raking into a high ridge, open a ditch on the ridge, will have flowered bulbs buried in it, the leaves are naturally retained.

  About a month later, the leaves withered and dormant, this time dig up the bulb, cut off the fibrous roots, and cut along the base of the yellowed leaves, and then buried bulbs, the depth of 10 cm is appropriate, while the application of rotted cake fertiliser or human urine, and then raked flat. Can not figure to save trouble, to the pot a buried thing, because the bulbs to spend a long time in the soil in the spring, summer, autumn three seasons, especially in summer and autumn, high temperature and heat, bulbs buried in it, and no leaves on it, if you forget to give them watering and fertilising, it will result in drought death.

  After dealing with the bulbs, the work that follows is the daily care and management, usually as long as you pay attention to give the garden enough nutrients, while keeping the garden moist but not waterlogged, the bulbs can grow naturally. Wait until November, December, and then dig out the bulbs, then you will find that the old bulbs have rotted and become empty, but it is around the reproduction of many large and small bulbs. Pick out those big buds more bulbs, wash the soil, peel off the surface of the brown film, and then put it outside in the sun for a few hours, and then use a knife in the top of the ball to make a “10” shaped incision, the depth of the scale not to injure the buds within the eye to the degree, in order to facilitate the buds, leaves grow. Soak in water for 24 hours, wash the gelatinous mucus flowing out of the incision, you can carry out normal aquaculture. Usually 3 days later, the ball bottom can grow white fibrous roots, the ball top bud eye also gradually sprout leaves. As for those small bulbs, because the year will not bloom, let them grow in the soil for another year, to be the next year after the development of strong, and then dug out for aquaculture.

Silver acacia breeding points

  The economic value of Acacia is very high, drought tolerance is strong, it is very suitable for forestation of barren mountains, in addition, the leaves of Acacia can be used as green manure and livestock feed. It is not difficult to cultivate Acacia artificially, and the propagation can be done by transplanting or direct seeding.

Silver acacia

  Transplanting method

  1、Seedling bed preparation

  After ploughing, get rid of weeds, start the bed, the spoke 1.5~2.0m×8~10m, apply appropriate amount of fertiliser, acidic soil (PH5.5 or below) add 50~100kg of lime per mu.

  2, seed treatment

  Soak in hot water (82 ℃) for 3-5 minutes, or boiling water (100 ℃) for 50-100 seconds, cool and dry mixed with silver acacia rhizobium species made of pill-coated seeds.

  3、Sowing

  When the temperature stabilises above 15℃, sow treated Acacia seeds in rows on the seedbed, with a spacing of 1O×35cm and a mulch of 2-3cm. Keep the soil moist for a week after sowing. If you don’t have a seedbed, you can also use nutrient cups to raise seedlings.

  4, transplanting

  Seedling height of 0.2 ~ 1.0 m can be transplanted to hole planting the best results, hole diameter of 60 cm, 50 cm deep, the appropriate amount of phosphate fertiliser, lime and organic fertilizer, plant spacing 60 ~ 80 × 100 ~ 150 cm. Transplantation should be in rainy days or watering the root water.

  5, management

  Seedlings planted after the early growth of slow, pay attention to the removal of impurities, soil cultivation. If the root nodule is too little or no root nodule is found, apply urea 2 kg per mu.

  Second, live method

  Applicable to the establishment of a large area of manually harvested land or grazing land, with hand sowing or machine sowing, but to deal with the ground (clean up weeds and scrub, ploughing and harrowing). Sowing should be as far as possible with grass forage such as dogweed, broad-leaved bird barnyard strip interplanting, the ratio of 1: l ~ 3. First sowing silver acacia 1 line, after the seedling and then sowing grass forage 1 ~ 3 rows, strip (row) distance of about 90 cm. The amount of silver acacia seed sown is 0.5kg per mu.

String leaf pine scented grass breeding points

  String-leaved pine scented grass, also known as send grass, native to North America, artificial cultivation is not difficult, ideal for large-scale planting as fodder, but also very suitable for farmers around the house, roadside ditch sporadic planting.

Stringleaf Cedarwood

  Stringleaf clover can be propagated asexually. Under rough management conditions, the survival rate of cuttings with underground stems can reach 89.8%, and it can achieve a faster growth advantage than that of live seedlings, and it can achieve good biological yield in a short period of time; it is expected to be able to bloom and bear fruits in the same year (further observation and testing are needed). Propagation from shoot cuttings of Pinellia ternata is a practical and feasible method, but suffers from the shortcomings of labour-intensive and costly manual collection of stem segments and a low reproduction coefficient. In addition to using stem cuttings, it may be possible to propagate Stringleaf Pine-Scented Grass using leaf cuttings.

Succulents spread the cause of analysis

  Succulents in the process of growing leaves open or even spread out the appearance is known as the spread of the cake, succulent layered look is more beautiful, when succulents appear to spread the cake will be more unpopular, so what exactly is the reason for the situation will cause succulents to spread the cake? I summarised three reasons for you, friends who do not know can come to learn.

Chihuahua

  First, the normal growth period, leaf spread growth

  This situation of spreading the cake, is normal, since to grow, spread is necessary, as long as the amplitude is not too large, the leaves do not turn down can be. Usually the cabbage shape of succulent plants indicates a semi-dormant period, some of the succulent after express transport, the leaves will also be wrapped, after slowing down the leaves spread, some enthusiasts will instead feel puzzled, succulent plant leaves spread is how? There is another situation belongs to the influence of the Korean meat, excessive pursuit of succulent extreme beauty, for spreading this thing also has a relatively high standard. To avoid this situation of spreading the cake, less water, more sun more abuse meat, may be able to meet this pursuit.

  Second, water and lack of light, caused by the spread of the cake

  This situation is more common, usually more water or insufficient light, or a combination of the two caused by the situation, the corresponding symptom is the leaf spread, the lower leaves and the upper leaves of the state of the obvious incoherence, the heart of the leaf may be whitish, the leaf colour will also appear to be lighter, the situation of the spread of the cake, if ignored, the next symptom triggered by the symptoms is often futile growth. Avoid this situation, you can reduce watering, increase light, depending on the degree of succulent spread, decide whether to water, in general, the leaf spread is succulent feel enough moisture, spread to enhance transpiration, the excess water transpiration out, wrapped up, it is a move to reduce water loss.

Chihuahua

  Third, the impact of light, caused by sudden exposure to sunlight

  This situation is a promoted version of the second situation above, because succulent plants show a tendency to spread the cake, in order to avoid this situation, suddenly from the less light / no light environment to take to the more light / full light environment, if the plant is dehydrated at the moment, the large light is easy to cause the leaves to be sun soft turn over, with the noodle like, hanging down. If too much water, and easy to cause the leaves to crack, to avoid this situation is to gradually increase the light, do not increase too much sunshine at once, moderate watering, strengthen ventilation. This situation of the spread of the cake, usually a short period of time can not be resolved, the sunburned leaves can not be restored to its original state, can only hope that the later care, renewed beauty. The ones that are more prone to this symptom are usually succulents with thin and long leaves, such as Jade Butterfly, Jade Dragon Goddess of Mercy, Black Mage and so on.

  It can also be understood that the leaves themselves were weakened or grown in a not very healthy environment, at once can not withstand the normal care environment.

  Many varieties will appear in the situation, usually succulent after the appearance of this situation need to pay attention to up, although the succulent spread big cake when it will not die, but also is a kind of preview of your feeding problems, so often observe your succulent, there are problems in time to find is the most important.

Cyclamen chlorosis symptoms and control measures

Cyclamen

  As the city flower of Qingzhou City, Shandong Province, cyclamen must have a different image and connotation from other flowers. At present, this flower has become a more commonly planted flowers, but many flower lovers in the course of breeding cyclamen will often be withered disease suddenly attacked to surprise, resulting in their hands and feet, so when encountered this flower disease how to do? The following is a detailed analysis of the causes of cyclamen chlorosis and control measures.

  Symptoms

  The disease is caused by Fusarium, the early stage of the disease, part of the plant leaves yellow, sunny day plant leaves show wilting, night recovery, wilting again during the day, until death. The petiole is oedematous, and sometimes the epidermis is longitudinally split. Under high air humidity, cotton wool-like white colonies, sometimes with a reddish colour, grow from the spots. Chlorosis is a soil-borne disease, and the affected parts turn brown and necrotic from the bottom up. The bulb of the diseased plant is cut open horizontally, and the vascular bundles can be seen browning on the cross-section, and the bulb generally does not rot.

  Second, the transmission pathway

  Chlorosis to mycelium or proto-wall spores with the remains of the disease in the soil or attached to the seed overwintering. The pathogen generally invades from young roots or wounds, enters the vascular bundles, clogs the conduit, produces toxic substances, resulting in bulb leaves turning yellow and dying. The disease is more serious under high temperature and humid conditions, and the pathogen spreads through water flow.

  Third, the onset of conditions

  Years of cultivation of cyclamen greenhouse, due to soil with bacteria, with watering pathogen from the bottom hole of the pot into the root infiltration. The plants with weak growth and root wounds have a high possibility of being infested. The disease develops annually in facility cultivation, with peaks in July and August.

Cyclamen

  Preventive measures

  Most of the drugs do not have obvious therapeutic effect after the occurrence of withering disease, and the production should focus on prevention and comprehensive treatment.

  1. Disinfection of facilities

  When the cyclamen are all sold, carry out thorough cleaning and sterilisation of the shed, removing dead leaves, flower remnants, weeds and other wastes after disinfection. Growing season can be carried out before the cyclamen buds extend: out of the leaves, with Chlorothalonil fumigant fumigant 3 times, the first and the third interval of four or five days, the second and the third interval of 7 to 10 days. The area of 1 acre of solar greenhouse each, the amount of three or four boxes. After 5 p.m. to ignite the fumigant, the greenhouse sealed for more than four hours and then release the wind.

  2. Seed disinfection

  Sowing with 1000 times potassium permanganate soaked for 12 hours, with water to remove the liquid after sowing.

  3. Substrate disinfection

  Conventional substrate disinfection in the week before potting, per cubic metre of ground myclobutanil 500 grams mixed soil, or spray 1000 times potassium permanganate. Can also be used in a month before potting mix soil, 20 to 30 grams per square metre. After disinfection, pay attention to protect the substrate to prevent secondary pollution. Turn the disinfected substrate 7 days before use to make it breathable and evaporate the residual drugs.

  4.Ground disinfection

  First of all, the ground is thoroughly scraped, and then sprayed 1000 times potassium permanganate, or 3000 grams of fungicide per acre mixed with an appropriate amount of clean river sand, evenly spread on the ground h. 30 to 60 grams per square metre of beats by dre, plus an appropriate amount of clean river sand sprinkled, turn over 20 cm deep, covered with mulch on the top. Soil temperature 10 ℃ fumigation 27 days, 15 ℃ fumigation 20 days, 20 ℃ fumigation 16 days, 25 ℃ fumigation 13 days.

  5. Sterilisation of pots

  The pots have been used with 1000 times potassium permanganate soaked for 2 hours, available under the condition of new pots.

  6. Cultivate pots off the ground

  If possible, set up elevated special flower beds or use flower pot racks to keep flower pots off the ground.

  7. Chemical control

  Disease-affected plants found or removed and destroyed, or with 70% metribuzin 500 grams, plus 5 kg of clean river sand, and no pollution of the honeycomb coal sieve slag mixed dry sprinkled on the potting soil of the diseased plants, once every 3 days, and then sprinkled 3 times. With 70% methyltropazine 800 to 1000 times liquid, 80% polymyxin 800 to 1000 times liquid, kill toxaphene 800 times liquid, benomyl 2000 times liquid alternately used to irrigate the roots of each plant each time to irrigate the amount of 100 ml, every 7 to 10 days once.

  If you do not read the above introduction, I believe that not a professional flower and plant breeders will never disinfect the seeds! In fact, chlorosis is a lot of flowers susceptible to disease, but as long as the timely remedy, can still be bright and beautiful Oh!
