How to raise chrysanthemum seedlings? When is cinchona suitable for sowing?

Soil:Cinchona is best planted in loose, well-ventilated, humus-rich soil. Loosen the soil before planting cinchona, loosen the soil after rain is conducive to the respiration of the roots of cinchona, and weeding once a week in the rainy season.

Watering:Chowney is easy to cultivate, watered once after planting, and then controlled watering to prevent the plant from growing. <>

Lighting:Fertilization:Before planting cinchona, the soil can be used as basal fertilizer (1 kg square meter) with rotten leaves, and when the growth period of cinchona is transitioned to the flowering period, fertilization should be stopped, and top dressing should be carried out after 4 flower buds.

Seedlings are sown in spring, and generally cannot bloom in that year. This may be due to the fact that the seedlings need to grow to a certain size and can only differentiate at low temperatures. Therefore, seedlings should be raised in autumn and overwinter when the seedlings grow to a certain size.

It can safely overwinter in the low temperatures of openfield-32. The author has experimented for many years that in the cold regions of the north, it should be sown about 70 days before the occurrence of freezing at the latest, so that the seedlings can have a certain amount of growth, and the early sowing makes the seedlings have a certain amount of growth. If you raise seedlings in a protected area in the spring, you can grow large seedlings in about 60 days, and you usually need to wait for the next year to bloom.

Chrysanthemum is often propagated by sowing. Spring sowing in April, 420 seeds per gram, germination temperature 13-16, germination 14-21 days after sowing. The germination rate is high, but the germination is not neat. It can also be propagated by cuttings in summer and by ramifications in autumn.

When sowing seeds, you should open the seed bag and sprinkle the seeds directly into the pot, or mix the seeds into the fine sand and sprinkle them evenly into the pot. After sowing, it needs to be covered with a layer of fine soil, and then covered with newspapers and other items, so that it can reduce the evaporation of water, and before the seeds germinate, it is necessary to keep the soil moist, and not to let the seedbed dry and wet.

Chrysanthemum likes strong direct light, and it is easy to grow in the shade, and it is a short-day plant.

After the seedlings are planted, the soil should be loosened before the new branches grow, and the soil should be loosened for breathing after the rain, and weeding once a week in the rainy season.

Mode of reproduction. In fact, the reproduction ability of cinchona is very strong, if you want to breed extra, you can breed by sowing seeds or cuttings. The following is a brief introduction to the breeding methods of these two grips.

Seeding and propagation methods.

Sowing can be done in March-April every year. The seeds are spread directly on the sand, which is then topped with a thin layer of soil. Before sowing, all soil chains should be thoroughly watered.

After sowing, the soil should maintain the same humidity and can be covered with plastic film. Then, the membrane should be opened in the morning and evening to breathe, and the rest of the time should be closed. When the seeds germinate, the plastic film is removed and then placed in a place where the shed skin is resistant to scattered light.

When one or two leaves have grown, it is ready for transplantation.

Dividing propagation method.

This method is very simple, because the cinchona itself is very reproductive, and it only needs to dig out its branches to be planted, which can be carried out during its growing season. However, it should be noted that the newly planted ramets should not be directly exposed to the sun, and they should be maintained normally after the slow seedling period. It can also be propagated by cuttings, and cuttings can also be used in the hot summer months, but this method is rarely used.

If you want to grow cinchona, you can propagate it by cuttings in the spring. Reasonable maintenance, after the growth of young chrysanthemum plants is stable in the later stage, it can be planted and raised in loose and breathable potting soil. After planting, water in moderation, water control during the maintenance period, and avoid direct sunlight.

After the chrysanthemum is planted in the later stage, it can be given sufficient light, water and fertilizer.

Chowney can be propagated by cuttings, which is suitable for spring and autumn and has a high survival rate. Cut the young branches of cinchona, cut them in loose and breathable soil, reasonable maintenance, generally about 30 days to take root. Once planted, it can be transplanted and raised in loose, fertile and well-drained potting soil.

Once the chrysanthemum is planted, it needs to be watered appropriately to soak the soil. Keep the cinchona indoors in a well-ventilated location away from direct sunlight. During the curing period, it is necessary to control the amount of watering, and water the chrysanthemum in an appropriate amount to keep the soil moist.

In the later stage, after the chrysanthemum adapts to the new soil, it can be maintained normally.

After the chrysanthemum adapts to the new soil, it needs to be given sufficient light, water and fertilizer. Cinchona likes light, and in spring and autumn, it can be moved to a well-lit location outdoors, which is conducive to the growth of branches and leaves. During the maintenance period, it is necessary to water and fertilize appropriately, keep the soil moist, and ensure that the nutrients are sufficient, which is conducive to the growth of cinchona.

If it is indoor maintenance, it is necessary to place the chrysanthemum in a well-ventilated location during the maintenance period. Open windows frequently to keep indoor air circulation, which is conducive to the growth of chrysanthemum branches and leaves. In the later stage of maintenance, it is necessary to pluck and prune the cinchona, and cut off its dead branches, weak branches and long branches, which can save nutrients and enhance ornamentality.

There are many propagation methods of chrysanthemum, including sowing propagation, cuttings propagation and branch propagation. Seeding is generally suitable for early spring, and high-quality seeds are selected and sown in loose and breathable soil. Propagation by cuttings is generally suitable for summer and autumn, when the sturdy young branches of the mother plant are pruned, trimmed and dried, and then cut in potting soil.

Chowney is more adaptable and has many ways to reproduce, but seeding is more commonly used. Sowing propagation is generally suitable for early spring, with full, high-quality seeds and loose, airy fertile soil. After the soil is disinfected, the seeds can be sown in the potting soil, covered with a layer of fine soil, and watered appropriately to soak the soil.

In early spring, when the temperature is low, the pot can be covered with a layer of glass after sowing to keep warm and moisturize. Place the pot in a well-lit and well-ventilated location to give the seeds plenty of light. During the maintenance period, it is necessary to water appropriately to keep the soil moist and provide sufficient water for the seeds, which is conducive to seed germination.

Chowney can also be propagated by cuttings, and the survival rate is relatively high. Propagation by cuttings is generally suitable for summer or autumn periods, when the robust young shoots of the chrysanthemum are cut, the branches are pruned, they are soaked in rooting water and dried. After drying, it can be cut into loose and breathable soil, and the water needs to be controlled during the curing period to keep the soil moist.

Cinchona can also be propagated by divides, which is generally suitable for spring or autumn. During the dividing period, it is necessary to depot the chrysanthemum, divide the robust young plants at the roots, and plant them. Young plants are planted in loose, airy, fertile soil, and the roots need to be protected from direct sunlight before the roots can adapt to the new soil.

1. Seed selection: When planting cinchona, you need to choose seeds with full grains and no disease, and then germinate them. 2. Planting:

Chrysanthemum seeds are sown on loose and fertile sandy loam soil and covered with a layer of plant ash. 3. Maintenance: After the chrysanthemum emerges, it needs to be moved to a bright place, and a phosphorus cultivation and potassium fertilizer should be applied.

1. Select the seeds

Chowney can be planted using the method of sowing, the use of this method first needs to pick out the full and shiny seeds, those shriveled seeds will not germinate, the seeds of cinchona are smaller, if you want to plant a large area, we can mix the seeds evenly in fine sand, and then sow them.

2. Sowing method

Chowney does not have high requirements for soil, but it is most suitable to grow in loose and breathable, well-drained soil, after sowing, you need to sprinkle a thin layer of soil on the surface of the seed, and then water, so that the soil is in a slightly moist state, do a good job of light and temperature management, and soon the seeds can germinate.

3. Seedling management

Newly germinated chrysanthemum seeds are very fragile, at this time need to be carefully maintained, the temperature is more suitable at about 20, and then the plant needs to be irradiated with an appropriate amount of scattered light, which will help it grow quickly, and then the plant can be transplanted and planted after the growth is stable. It will be able to bloom in a few months.
