Planting time and method of Chili vegetable

Planting time: the seeds are usually sown from the end of August to the beginning of September. Prepare the seedbed: choose the shady area as the seedbed, require good drainage and irrigation, loose and fertile, deep soil layer and no diseases and insect pests of sandy loam, deeply turn the soil and then apply quicklime disinfection, and then apply fertilizer. Strong seedlings: in order to promote the growth of seedlings, fertilizers are needed after each seedling. Transplanting fertilizer: should be transplant in sunny or cloudy days, after planting can be topdressing about 2-3 times. Control of diseases and insect pests: rational use of drugs.

First, sowing time

The main results are as follows: 1. the seeds are usually sown from late August to mid-September, and the best sowing time is in early September.

2. The suitable temperature for seed germination is about 20-28 ℃. In order to make the surface of the room moist, rotten dung water can be applied before sowing, and then sowed evenly. In order to improve the germination rate, it can be covered with a layer of 0.5cm thick sand or plant ash, stone millet, etc., and finally covered with rice straw or sunshade net after spraying pesticides.

3. When the germination rate reaches 75%, the sunshade net and straw can be removed in the evening to avoid the growth of young seedlings, such as high temperature and drought in summer, dry soil, watering in the early morning or evening to protect seedlings, sunshade net or small arch shed, and so on.

Second, prepare the seedbed

The main results are as follows: 1. The seedbed should be selected in the shady area, the soil should be loose and fertile, the drainage and irrigation conditions are good, the soil layer is deep, and the sandy loam soil without diseases and insect pests is better. Then turn the soil deeply, spread quicklime to disinfect, and adjust the soil acidity and alkalinity.

2. Note that if only quicklime is applied, the soil will become hard and thin, so it is necessary to apply basic fertilizer, mainly rotten human and animal manure, together with calcium superphosphate, boron, magnesium, zinc and other trace elements, and then mix the seedbed soil evenly and level. the width of the box is about 1.7m.

3. Strong seedlings

The main results are as follows: (1) when the seedlings grow to 1-2 true leaves, the distance between seedlings is about 3-4cm, and then fertilize, about 1800-2000 kg of clear water dung per mu, together with 5 kg of urea.

(2) when the true leaves of the seedlings grow to 3-4 pieces, the distance between seedlings is about 5-6 cm, and fertilizers are applied at the same time. 2000-2500 kg of rotten clear water manure per mu and 5-6 kg of urea are applied together, and the third interseedling and fertilization can be carried out according to the specific conditions.

IV. Transplanting and fertilization

The main results are as follows: 1. We should choose to transplant with soil in sunny day or sunny day, and water thoroughly after planting. In order to promote the growth of seedlings, human and animal fertilizer and water can be applied about 2-3 times after planting.

2. About 2-3 days after transplanting, fixed root fertilizer can be applied, about 3000-3500 kg of rotten human and animal manure per mu, about 15 days after transplanting, topdressing can be carried out, and about 2500-3000 kg of human and animal manure per mu can be applied together with 20 kg of urea. About 35 days after transplanting, about 3000-3500 kg of human and animal urine manure can be applied per mu, and about 20 kg of superphosphate can be applied. About 15 kg of potassium sulfate and 20 kg of urea are applied together.

V. Prevention and control of diseases and insect pests

1. The main diseases and insect pests of children's vegetables are aphids and virus diseases. To control aphids, you can spray imidacloprid, compound remonstrant insecticides 1000 times or trap them with yellow board, about every 7-10 days.

2. For the prevention and control of downy mildew, 64% poisonous alum can be sprayed, 2500 times of EC can be sprayed for the control of yellow striped beetle, and 3500-4000 times of agricultural streptomycin soluble powder can be used for the prevention and control of soft rot. If the disease is more serious, spray it again in about 8-10 days, and stop spraying within 15 days before harvest.
