　　Begonia’s seeds are small and short-lived, so if the harvested seeds are not sown in time, it will have a great impact on the seedling rate. Generally, begonias are mainly propagated by sowing seeds and cuttings, and I will briefly introduce these two propagation methods for you.

Begonia

　　1, sowing method: East China generally in the spring April-May and autumn August-September is most suitable. The seeds should be evenly sown on the fine mud in the pot (no need to cover the soil). And then the seed pot with the bottom of the pot absorbent method to absorb enough water, and then covered with a piece of glass in the semi-shade, 10 days after the germination. Seedlings sown in the spring, the autumn of the year will be able to bloom.

　　2, cuttings: cuttings more in March-May or September-October, with vegetative sandy soil as cuttings substrate, can also be cut directly on plastic pots, need to insert the section into the soil. Rooting takes place in more than 20 days under sheltered and insulated conditions. Older perennials can be divided, and at the same time pruned to promote the development of new lateral branches, in order to form a complete plant.

　　Cultivation of the large-flowered alstroemeria (details) is less difficult, but you need to pay attention to the appropriate water and fertiliser, otherwise it will affect the pregnancy buds and flowers, and will have a great impact on the acquisition of seeds. Artificial propagation of large-flowered alstroemeria can use the method of sowing seeds or cuttings, I will give you a brief introduction.

Alstroemeria grandiflora

　　The large-flowered alstroemeria does not require much soil, is cold and drought-resistant, and has a suitable germination temperature of 15 to 20 degrees Celsius. It is easy to cultivate and can often reproduce by itself. In production, it is mostly sown or planted, and cuttings can also be taken in summer.

　　The seeding propagation of the large-flowered alstroemeria is usually carried out in the spring, and the flower can bloom 4 months after sowing. Open field planting is often self-sowing reproduction. It is also possible to divide the plants in autumn. Select the more vigorous growth of the plant, dig up and cut the root with a sharp knife, cut off the yellow leaves, and plant separately.

　　The ball pine for the Sedum family Sedum genus of succulents, because the ball pine plant is short and short branching, the whole plant is almost like a ball, so the ornamental value is relatively high. However, the flowers are not of high ornamental value, so when the inflorescences appear, you can cut them off as soon as possible to avoid consuming too much nutrients on the plant.

Ponderosa Pine

　　The common way of propagation is to take cuttings to propagate, with the highest survival rate in spring and autumn, such as the winter has perfect warming measures can also be, the summer heat plant is in the dormant period and should not be carried out. Spike should be cut strong and full, no pests and diseases, with the top of the branch, the length of the requirements are not strict, drying 1 to 2 days, such as wound drying, directly inserted in a small pot or seedbed, inserted to keep the soil moist, but to avoid stagnant water, easy rooting.

　　Purple goose down is not difficult to cultivate, but during cultivation, purple goose down may occasionally emit an unpleasant odour, so it is common to remove the flower buds when they bloom. Artificial propagation of purple velvet is not difficult, generally based on cuttings, I will give you a brief introduction to the propagation of purple velvet cuttings.

Purple goose down

　　Purple goose down is easy to propagate, mainly by cuttings. It is often carried out in April-June in combination with pot turning and pruning. Cut the tip of the branch about 10 cm long as a spike, after insertion to maintain room temperature 20-25 ℃, shade and high relative humidity of the air, about 15 days can be rooted and live. In the high relative humidity of the air, the plant will often produce aerial roots at the base of the stem or creeping growth of the stem nodes, can be cut directly from the pot. The seedbed substrate should not be too wet when taking cuttings, otherwise the fleshy spikes will rot easily. Can also be water plugging, the branch into the water, more than 10 days can be rooted to survive.

　　Marigold has the meaning of longevity, its flower language is sweet love, health and longevity. Many friends can clearly distinguish marigolds, and now there are many friends will marigold potted plants for ornamental purposes. Generally marigold propagation method of cuttings, I will introduce you to the notes of marigold cuttings.

Marigold

　　1, prepare the soil. Marigolds use a substrate of 40% of the husk ash and 60% of the river sand, husk ash is not only loose drainage, but also can effectively prevent the rot of the spike. After mixing the substrate, spray water moderately, so that the water content of the substrate reaches about 60%, and use it after spraying water for 1 hour.

　　2. Spike insertion. Marigold spike generally stay 3 to 5 sections, with or without the top bud can be. The leaves at the base of the spike should be pruned cleanly so as not to lose too much water. When pruning the wound must be smooth, the lower part of the wound of the spike is cut diagonally at 45 degrees, and the upper part of the wound is cut flat.

　　3, cuttings. First of all, use the size of the spike a small wooden stick in the substrate hole, plant spacing 3 cm, row spacing 5 cm. The spike will be gently inserted into the pre-drilled hole, the depth of the spike 1 / 3, with the index finger and thumb slightly around the spike sand press.

　　4, Management. After the cuttings, use a sprayer to spray the leaves can be wet, too much water can easily lead to spike rot, and then covered with a good shade net over 80 cm high, and then sprayed with fog once a day at 10 am and 5 pm or so, just spraying wet leaves is appropriate. The area where the cuttings are placed should not be exposed to rain or western sunlight, otherwise the work will be wasted. If the shade netting is not too dense, it is best to cover it with two layers of shade netting.

　　Artificial propagation of Fagus sylvatica can be done by sowing, dividing and taking cuttings, but because the seeds of Fagus sylvatica are relatively small, so the germination rate is also lower, and if it is for production use, sowing propagation is generally not recommended.

Ficus religiosa

　　Seed propagation

　　Generally in the spring in mid to late March when the temperature is stable above 10 ℃, the use of greenhouse seeding seedlings. Before sowing, 667 square metres of seedling beds should be fertilised with 3,000 kilograms of rotted organic fertiliser, and then the seedling beds should be made good, and the width of the beds should be 1.2 metres. Seedbed watering through the bottom of the water, sowing seeds while wet, then covered with fine soil 0.2 ~ 0.5 cm, after sowing, pay attention to heat preservation, moisture preservation, daytime temperature is maintained at 25 ~ 30 ℃, up to 32 ℃ to be ventilated to cool down the temperature, sowing 8 ~ 10 days after the seedling can come out. When the seedling height of 5 cm, combined with ploughing and weeding, between the thin and weak seedlings, to maintain the seedling spacing 2 ~ 3 cm; seedling watering in moderation, and often keep the bed wet. In the seedling age of about 100 days, seedling height of 10 ~ 15 cm, true leaves 5 ~ 6 pieces, can be planted in the field. Facility cultivation of heart lettuce does not flower because of continuous harvesting of young stems and leaves. Seed propagation is generally not used in production.

　　Second, split-plant reproduction

　　Split-plant reproduction is generally carried out in late March. Feiqi dug up the roots, choose strong plants for planting, cut it into several plants, cut down each section of the root as much as possible with root buds, in order to shorten the time of slowing down the seedling, and then planted in the seedbed or planting holes, and diligently watering to keep wet. The planting propagation has a high survival rate, the method is simple, but the reproduction coefficient is low, suitable for small-area production and propagation.

　　Third, cuttings propagation

　　Fei Cai has strong tillering ability, fleshy stems, clumps, fleshy roots are fat, plant height 25 ~ 40 cm. Feicai cuttings propagation technology is easy to operate, not only the survival rate is high, and the seedling growth is robust, so the production is often used in this way.

　　1, cuttings propagation time. Spring and autumn temperatures are more suitable, Feicai growth is more vigorous, generally in March to April and August to September for seedling cuttings propagation.

　　2, seed plant selection. Cuttings propagation should be selected without pests and diseases, with a certain degree of maturity of the growth of robust branches, can not choose too young or too old branches cuttings.

　　3, seedbed preparation. Fei Cai generally use seedbed cuttings, and then transplanted to the field after survival, so that it is easy to manage the seedling period, but also can greatly improve the survival rate of cuttings. Cuttings should be prepared before the seedbed, should choose the terrain is high and dry, well-drained, deep soil, fertile and loose sandy loam plots for nursery beds. Before the nursery, 667 square metres of seedbed sprinkled with well-rotted high-quality organic fertiliser 2000 to 3000 kg, the land deep ploughing and fine harrowing, and then made into a ditch width of 25 cm, bed height 20 cm, bed width of 100 cm of the nursery bed.

　　4, seed plant treatment. Select the middle and upper part of the full section for the spike, each spike to stay on the 2 ~ 4 sections, about 10 cm long, the upper end of the plug to stay 2 ~ 3 leaves, the lower end of the leaves cut off, cuttings in the pre-fixed seedbed. In order to improve the survival rate of cuttings, cuttings will be selected before the branch 50 rooted into a handful, and then the base soaked in a concentration of 50 mg / kg of rooting powder solution for 12 hours, or in a concentration of 20 mg / kg of naphthalene acetic acid solution for 15 to 20 minutes, or in a concentration of 15 to 30 mg / kg of indole butyric acid solution for 15 to 20 minutes.

　　5, Cuttings. In the nursery bed according to 10 cm row spacing cuttings ditch, ditch depth of 4 ~ 5 cm, 10 rows of cuttings per bed, according to the plant spacing of 5 cm will be inserted into the seedbed cuttings in the ditch, into the soil depth of 3 ~ 5 cm is appropriate.

　　6, cuttings seedbed management. Spike seedling cuttings, watering immediately after the cuttings, and pay attention to heat preservation, moisture; spring cuttings propagation should be covered with a small arch shelter heat preservation, moisture preservation, daytime temperature is maintained at 20 ~ 30 ℃; summer and autumn propagation, due to high temperatures, rain, humidity, should be covered with shade netting in order to keep out the rain and sun.
