If it is a newly planted seedling, it is not suitable for fertilization immediately after planting. After the seedlings survive (showing new roots and buds) and have 2-3 new leaves, the organic fertilizer can be applied thinly, and after the seedlings grow normally, the chemical fertilizer can be applied for a few times, and the normal dose can be applied regularly after the seedlings enter the vigorous period, generally 25-30kg/ mu.

The absorption ratio of colorful sweet pepper to nitrogen, phosphorus and potassium is 4: 1:3. Water should be controlled before fruiting and the soil should be kept moist after fruiting. In the fruiting period, according to the growth trend, apply fertilizer for 2-4 times, and spray 0.5% potassium dihydrogen phosphate on the leaves for 2-3 times. Spraying 0.2% borax twice on the leaves from flowering stage to early fruiting stage can improve the fruiting rate.

1, branch management

Pot-cut colorful peppers generally leave two main branches. Other lateral branches need to be removed to help the main plant absorb enough nutrients.

Step 2 water it

The root system of colorful sweet pepper is underdeveloped, and it is not tolerant to drought and waterlogging. The characteristics of its water demand are: the water demand of the plant itself is not large, but it needs to be watered frequently to increase production.

3, pest control

① Disease prevention and control: The main diseases are epidemics, which can be sprayed with Cloupe solution and antivirus alum solution; virus diseases can be prevented with virus A, and virus double solution: gray poisoning is generally prevented with Nongliling double solution.

(2) Pest control: The main pests are aphids, leaf snails (red spider) and tea yellow snails, which can be controlled by 800-fold solution of Pichonglin and Aimeile; The tobacco budworm can be prevented and treated with Nongdi Lebei solution and Kakukebei solution.

Step 4: sow seeds

Fill the soil into the flowerpot, and sow seeds according to the size of the flowerpot (it is best to sow by point method to prevent the problem of overcrowding when plants grow). Generally, 5-7 seeds can be sown, and then cover with a layer of soil, and put it in an environment of 25-30℃ to wait for sowing and germination.

5. Temperature and illumination

Multicolored sweet pepper is a short-day crop. Compared with other eggplants and fruits and vegetables, they have light resistance. It needs a certain growth temperature. The growth temperature in the back-planting growth period is 25-30℃, not less than 18℃ at night, not less than 2 1-26℃ in the day and not less than 15℃ at night. Therefore, care and temperature must be controlled when planting.
