How to raise nightshade? How to raise nightshade, cultivation methods and precautions for nightshade

1. Soil, if the soil for cultivating nightshade is evacuated soil, the soil is slightly acidic or neutral, pay attention to the permeability and drainage of the soil, and it is best to add a small amount of sandy soil in the basin.

4. Fertilization, the fertilization of evening primrose is mainly organic fertilizer, and the Spring Festival and summer should be fertilized in an appropriate amount, once every 20 days, but in moderation, fertilizer should be stopped in winter.

5. Change the pot, in early spring, we have to change the pot of the evening primrose every 2 years, before changing the pot, first dry the new soil in the sun for 3 days, disinfect, when changing the soil, remove part of the old roots of the nightshade, and water it after changing the soil, but do not produce stagnant water.

6. Precautions, nightshade cannot be put indoors for breeding, because it will cause dizziness and other uncomfortable feelings. The common disease of evening primrose is ring pattern disease, which should be found in time and in time.

1. Choose cuttings. Branches that grow robustly or without pests and diseases should be selected, and the branches that are in the middle and upper part of the year should be selected on the same plant, requiring short internodes, thick branches and leaves, and full bud tips, and it is not suitable to choose branches and long branches that are about to bloom.

2. Select the substrate. It is prepared with peat soil, humus soil and Gaza according to 3:3:4 respectively, and the bed soil prepared in this way has the characteristics of increasing bed temperature, water retention, aeration, fertility and acidity, and is suitable for branches to take root and sprout.

3. Before cuttings, treat the cuttings with ABT rooting powder and other agents, which has the effect of promoting rooting. The cuttings are cut into a section of 8 cm to 12 cm, with 2 to 3 buds on it, the incision of the lower part of the cuttings should be at the centimeter below the node, the incision should be smooth, the lower leaves are cut off, only the top 2 to 3 leaves are left, and the insertion depth is generally about 3 cm.

The insect pests of nightshade mainly include mites and shellfish, and the diseases are blight. The control of mites can be used anti-mite 23 emulsifiable concentrate 800 times, 73% gram mite 2000 times solution, etc. To control scale insects, 40% dimethoate emulsion can be used 600-800 times.

To prevent and control Fusarium wilt, 600-800 times of Fusarium wilt Rick and 600 times of 50% carbendazim can be used.

Planting nightshade requires soil preparation, plant treatment, soil planting, and maintenance.

1. Prepare the soil.

Usually choose to plant in the spring, before planting to prepare the soil, the soil with soft, good drainage, strong air permeability, rich in organic matter, and acidic, so that the soil environment its root system can better breathe growth, generally with peat, humus, coarse sand, base fertilizer to mix.

2. Treat the plants.

If it is a plant that has been cultivated for many years, it also needs to be pruned to the roots, so that it can better absorb water and nutrients in the later stage and promote vigorous growth.

3. Plant in the soil.

If it is a potted plant, first put a layer of broken bricks at the bottom of the pot to improve drainage and ventilation capacity, then put in nutrient soil, put in small seedlings to ensure that the root system is extended, and finally fill the soil and compact.

If it is planted in the ground, dig a hole of appropriate size, put the seedlings in, fill the soil and compact, and immediately water the root water after planting, and it must be watered thoroughly, so that the root system at the bottom can absorb enough water from Chang Sakura, which can promote recovery as soon as possible.

4. Later maintenance.

Provide a warm, well-ventilated and humid environment, and apply thin fertilizer frequently during the peak growing season.

Precautions for breeding

1. Change the pot and impermeable bush.

The growth rate of nightshade is fast, so the problem of changing pots can not be lazy, and repotting is carried out every spring, and by the way, pruning dead roots and old roots, and the germinating new root system is more conducive to the growth of nightshade. It is also possible to prune the areas that the plant is not satisfied with, and to shorten the long branches.

After changing the pot, pay attention when cultivating nightshade, do not water too much, keep the potting soil slightly moist, or wait for the leaves of the plant to wilt before watering to avoid rotting the roots.

2. Temperature. Potted planting nightshade in the winter to prevent frost damage, planting environment temperature can not be lower than 5, open-raised nightshade needs to be moved into indoor planting after the National Day, so as not to suddenly reduce the temperature, frost damage, so that the plant is damaged.

Nightshade needs to be repotted and changed once in April every year, can be mixed with humus and coarse river mud to make a wide substrate for nightshade soil, in the flowering period, winter must be put in full sunlight, can be watered every 2 3 days, but also every 10 15 days to apply liquid fertilizer, winter needs to maintain the temperature at 8 10 on it.

In April of spring every year, the nightshade needs to be removed from the potting soil, remove the old soil and rotten roots and old roots on the surface of the roots, and retain the robust roots.

Generally, nightshade is happy to be bathed in the sun, give it light during the daytime during the flowering period, then it can be prompted to bloom beautiful flowers in the evening, and give it enough sunlight in winter, which can help nightshade in winter, it is usually best to give it 4 6 hours of light, and in summer you need to do sunscreen measures.

Nightshade is like to grow in a humid environment, in the cultivation method of nightshade, generally need to be watered every 2 3 days, and in summer, water should be sprinkled on the leaves every morning and evening, and liquid fertilizer should be applied once every 10 15 days during the growth period of the year, and nitrogen, phosphorus and potassium fertilizer should be applied once every half a month during the flowering period, so that the flowers bloom continuously.

In fact, the negative tolerance of nightshade is very poor, it generally needs to grow at about 15 20, generally every winter when it needs to be moved to the greenhouse or indoor maintenance, it is best to maintain the temperature at 8 10, if the temperature is lower than 5 then the branches and leaves will gradually yellow, but also can make nightshade frostbite freeze to death.

Nightshade has a strong reproductive ability, it is generally in spring and autumn, can be propagated by cuttings, the mother plant needs to pick the branches with roots from the roots, comb the roots, and then insert them into the loose soil, control the ambient temperature at about 20, and wait for the branches of nightshade to take new roots.

Cultivation methods of nightshade: potting soil selection; temperature and light conditions; Watering; Fertilize; Change the pot at the right time.

1. Potting soil selection:

Flower pots are more suitable for clay pots or tile pots with good air permeability, and the volume is slightly larger. The soil is more suitable for loose, well-drained, organic-rich acidic soil, which can be prepared with peat soil and humus soil in the ratio of 3:3:4.

2. Temperature and light conditions:

The temperature of nightshade is generally kept at 12-33. But it is not cold-tolerant and is afraid of frost, so when the frost temperature decreases, it is moved indoors in time for maintenance, and the winter temperature is between 7-15. In addition, nightshade also likes light, so sufficient light and good ventilation are the keys to raising nightshade.

3. Watering: In the growing season, it is necessary to water enough, flowering in spring and summer often requires more water, and in winter it should be reduced to avoid the plant being frozen to death.

4. Fertilization: In the growth process of nightshade, liquid fertilizer needs to be applied every 10-15 days or so, and thin liquid fertilizer is applied every half month after the second half of April in Jianzao Town, which can ensure that Nightshade can bloom continuously from mid-May, and the flowering period can be extended.

5. Change the pot in a timely manner

The repotting time of evening primrose is generally carried out before leaving the room in early April in spring, when changing pots, part of the old soil and old roots are removed, and new culture soil is replaced, and it is recommended to re-prune appropriately to promote the growth of new branches.
