What are the planting techniques and management methods of hot pepper in greenhouse in spring? These four moves make chili peppers prolific!

Pepper is cultivated in all parts of our country, and its taste is deeply liked by consumers. With the development of protected cultivation technology, cultivation forms are diversified, and multiple crops can be cultivated throughout the year. What are the planting techniques and management methods for growing chili peppers in a greenhouse in spring? These 4 growths help to produce chili peppers!

Planting techniques and Management methods of Pepper in greenhouse in Spring

1. Planting time

Pepper is a temperature-loving vegetable, early-maturing cultivation of low temperature, early planting, high management costs, too late planting, affecting the improvement of production efficiency. Generally, seedlings are raised in late December, and it is more suitable to plant in mid-late March.

2. Seed selection

The varieties with strong disease resistance, low temperature tolerance, good weak light, fast fruit expansion, concentrated fruit setting, compact plant type and strong continuous fruit setting ability should be selected for early ripening cultivation in spring greenhouse, so as to improve the yield and economic benefit.

3. Prepare to plant the greenhouse

For planting hot pepper in greenhouse in early spring, the greenhouse should be buckled 15 days before planting to prevent the influence of bad weather, and it is also beneficial to baking and increasing the ground temperature. Chili peppers like warmth and are not resistant to frost. They are generally planted on sunny days in the middle and last ten days of March. The soil should be turned deeply before transplanting. Combined with 3000 kg of rotten farm manure, 120kg of cake fertilizer and 50kg of compound fertilizer per mu of land preparation. Then a ridge with a width of 80CM and a height of 20 CM was formed and covered with plastic film. Close the tuyere, according to the standard of 10 grams of sulfur per cubic meter, mix sulfur with sawdust or wheat bran, light the smoke, disinfect, ventilation after 48 hours, kill bacteria, can effectively reduce the occurrence of diseases.

4. Field management

Temperature: pepper seedlings basically do not let out within a week, accelerate slow seedling, slow seedling should be properly ventilated after slow seedling, generally slow seedling for about a week. Due to the rapid rise and fall of the temperature in the plastic film covered shed, the temperature should be released when the temperature exceeds 30 ℃ during the day. In the early stage, as the external temperature is still low, pay attention to the side wind, the release should start from the upper, it is appropriate to keep the temperature in the shed up to 25: 27 ℃ during the day, and pay attention to cold prevention at night. When the lowest temperature at night is stable at 15 ℃ in the first and middle of May, the greenhouse film can be removed and the open field management can be carried out.

Support: pepper cultivation in greenhouse, due to high temperature and humidity, compared with open field cultivation, vegetative growth is more exuberant, there are many stems and leaves, and the plant is easy to lodge. After planting, the plant should be fixed horizontally with a bamboo pole to prevent lodging. When the seedling grows to 30~40CM, fix the plant with a small bamboo pole. You can also insert a bamboo pole and pull a rope to support the hedge and fix the seedling frame at both ends and in the middle of each ridge.

Fertilizer and water: in the process of growth, pepper should be ploughed for many times to keep the soil loose, promote the growth of pepper root system, and help the plant to absorb water and nutrients. Pepper likes fertilizer and is tolerant to fertilizer. In the plant growth period, topdressing should be carried out many times to promote the high yield of pepper. In the early flowering period of hot pepper, combined with watering, 7 kg of urea per mu was applied, and 0.2% potassium dihydrogen phosphate was sprayed on the leaf surface for 3 times. In the full fruit stage, the plant has the highest demand for nutrition, which can be topdressing compound fertilizer for 1 or 2 times and applying 15 kg per mu each time. The root system of pepper is underdeveloped, neither waterlogging nor drought-tolerant, so the growth process requires high soil moisture and low air humidity. In order to improve the indoor temperature and reduce the air humidity, plastic film mulching is necessary, usually pay more attention to the ventilation and moisture drainage of the greenhouse. When watering, it is best to carry out after 8 o'clock in the morning, in the noon high temperature, proper ventilation and dehumidification. After the result, it is necessary to increase the times of watering and the amount of water, increase the times of ventilation and control air humidity.

In short, hot pepper planting in spring greenhouse must strengthen the management of temperature, moisture, humidity and nutrients, and cultivate strong seedlings as far as possible. We should be familiar with the symptoms of common diseases and insect pests and do early detection and early treatment. Only by doing these well can we improve the economic benefits of growing chili peppers.
