Green pepper evolved from the tropical region of Central and South America in North America. After long-term cultivation, domestication and artificial selection, the fruit volume increased, the pulp thickened, the spicy taste disappeared and the number of carpels and ovaries increased.

Cultivation and Management techniques of Green Pepper in Autumn and Winter

Autumn and winter greenhouse green pepper supply New Year's Day, Spring Festival market, colorful, high economic benefits, so how to cultivate green pepper in autumn and winter?

First, sowing and raising seedlings

Selection of heat-resistant, virus-resistant, fruit-type large early and middle-ripening varieties, our county has a larger promotion area is Bianjiao No. 1, in addition to Xinfeng No. 4, Luojiao No. 4, Daguo Zaofeng and so on. The suitable sowing date is about July 20, the amount of seeds used in the greenhouse is 75-100 grams per mu, and the seedling bed is 20 square meters. Raise seedlings in the greenhouse with top film and sunshade net, sow the seedling bed with enough water, cover the nutritious soil 1 cm thick after sowing, cover the seedling bed with film, cover the grass to keep moisture and cool down, check the germination and emergence every morning and evening from the 5th day after sowing, and remove the bedside grass and film when 60% of the seeds emerge. When the green pepper seedlings have 2-3 true leaves, in the rainy or sunny evening, in the greenhouse with top film and shading net, divide the seedlings with a nutrition bowl of 8 cm in diameter and irrigate the roots while dividing the seedlings. During the whole seedling stage, the mulch on the seedling shed was covered by day and night to keep the soil surface moist.

II. Timely colonization

The seedlings were 35-40 days old, 15-20 cm high and 6-7 true leaves, that is, from mid-August to early September, and planted after 3 pm on cloudy or sunny days. 4000 kg of rotten soil fertilizer was applied per mu 15 days before planting. Five days before planting, sparse dung water was applied once, and insecticidal (1500 times of 50% aldicarb) and fungicide (1500 times of aldicarb) were sprayed once, so that the soil was planted with fertilizer and medicine, and the nutrition bowl was watered thoroughly to ensure that the soil was not scattered. Planting row spacing 40 cm, plant spacing 25 cm, covering plastic film.

Third, strengthen management.

1. Light and temperature management

In the initial stage of planting, the sunshade net should be covered on the shed, and the agricultural film should be covered on rainy days and ventilated day and night. From the middle of September to the middle of October, the greenhouse should be covered with film for heat preservation at night, pay attention to ventilation during the day, keep the temperature of the greenhouse at 25-30 ℃, and no more than 32 ℃ around noon. When the night temperature in the greenhouse is lower than 10 ℃, that is, a small shed should be added in front of Frosts Descent, and as the external temperature continues to drop, grass mulch should be added to the shed to keep warm. On rainy and snowy days, the grass should be exposed at the right time every day.

2. Fertilizer management

Look at the seedling fertilization, 10 days after planting and the initial stage of fruit setting, 10 kg of high-quality compound fertilizer was applied to water per mu to control the amount of nitrogen fertilizer and prevent the overgrowth of plants.

3. Water management

There is no shortage of water in the seedling stage, keep the border surface moist during the fruit setting period, and do not use hot water to irrigate the seedlings and flood irrigation in high temperature and hot land. After November, due to the gradual decline of external temperature, the border surface is better on the dry side.

4. Hormone application

Flowers and buds are easy to fall in high temperature season, and the flower stalk is coated with 15 × 10 ~ (- 6)-20 × 10 ~ (- 6) solution.

5. Plant adjustment

The normal plant should remove the buds of one branch in time, the weak plants should also remove the buds of two branches to prevent the fruit from falling, the growing plants should keep the pepper from growing, cut off the tender shoots, ineffective branches and small buds after the first frost, and concentrate on nutrition to supply the fruit growth.

6. Pest control

Select high-efficiency, low-toxic, low-residue pesticides, the use of biological control, physical control and agricultural control, focusing on the prevention and control of virus diseases.
