Winter and spring pod pepper is the most important production gargle in pepper cultivation in the solar greenhouse. It is generally planted in mid-November and can be harvested in the early January of the following year until the second summer. The main cultivation techniques are now explained as follows: 1. Build a new type of energy-saving solar greenhouse for greenhouses, and comprehensively improve the structure of the existing solar greenhouse and environmental control technologies. The light transmittance of energy-saving solar greenhouses is generally 60% to 80%, and the difference between indoor and outdoor air temperatures can be maintained at 21 to 25°C. Even in the harsh winter season in the cold regions of the north, it is possible to achieve the production of thermophilic fruit and vegetables such as pepper without heating or slightly warming. There are many ways to classify solar greenhouses. According to the classification of wall materials, it can be divided into dry concrete base greenhouse, brick and stone structure greenhouse, composite structure greenhouse: According to the length of the back slope can be divided into long back slope greenhouse and short back slope greenhouse: According to the shape of the front roof can be divided into Two-fold, three-fold, arch-type, micro-arch greenhouses: According to the structure can be divided into bamboo and wood structure, steel and wood structure, reinforced concrete structure, steel structure and cable structure. The classification of structural forms can be used to summarize various types of greenhouses. Therefore, many types of greenhouses are classified according to this. 2. The selection of variety varieties should take into account the product flow direction and the adaptability of the varieties to the solar greenhouse. Combining the flow of goods to the market for the requirements of commodity peppers, pay attention to the selection of good varieties that are resistant to low temperature, low light, disease resistance, high yield, and high rate of results. At present, the main cultivars include Yijiao No.1, Hongguowang, Zhongjiao No.6, Zhongjiao No.7, bell pepper Zhongjiao No.5 and Jingtian No.3. 3. Fertilization, planting, planting, foot and deep plowing are the important conditions for the cultivation of peppers in greenhouses in winter and spring. The cultivation of pepper in solar greenhouses requires high basal fertilizer, generally requiring 8000 kg of organic fertilizer per acre, 50 kg of superphosphate, 100 kg of cooked cake fat, 40 kg of potassium chloride, and 20 kg of urea. Fertilize the soil deep into the soil and mix thoroughly with the soil. It can be cultivated with flat mulching, with a width of 60 to 65 cm, and a width of 30 cm. A vertical 10 cm deep and 20 cm wide groove is to be opened in the middle of the surface of the mulberry, so that the dark irrigation water can be applied under the membrane. The sorghum noodles can be made into low slopes with high slopes in the south to increase the light and increase the soil temperature. Also often used small high ridge film cultivation, generally ridge width 70 to 75 cm, groove width 50 cm, ridge height 15 cm, 2 rows per ridge planting, hole spacing 40 cm, 2 plants per hole. The number of seedlings per mu is 3200 to 3400, and about 6,500 pepper seedlings are planted. 4. When scientifically colonized and colonized, soil temperature should not be lower than 15°C. Colonization should be carried out on a sunny morning. Prepare everything in advance and strive to end planting around 14:00. Colonization can be planted by ditching and watering first, that is, 10 cm deep shallow ditch by row spacing. Before the planting, 2 to 3 days before the planting, the bottom water is poured, and after the watering, it is closed without ventilation to increase the soil temperature. It can also be watered after planting in order to facilitate rooting. 5. Temperature Management Temperature management in greenhouses in winter and spring is very important. The cultivation technology of winter peppers is not allowed to ventilate or lightly wind until after the planting, and maintains a high temperature and high humidity environment for about 7 days to promote seedling and hair growth. After the seedlings are regulated, the temperature is controlled by adjusting the ventilation volume. Shed temperature maintains daytime temperatures of 26-28°C, 16-18°C at night, and 10°C 10°C soil temperature. The temperature before the curtain was 10~14°C. As the peppers enter the result period, the temperature begins to drop, and the insulation work must be strengthened. Especially in the cold regions of the north, from the time of fruit setting to the harvest stage, it is necessary to increase the temperature, keep warm and increase the light as much as possible. If you insist on cleaning the shed film every day, put grass rakes in place as early as possible to maintain the night temperature, and increase the number of grasshoppers as much as possible to increase the night temperature. Maintain daytime temperatures in the sheds at 20-25°C and night temperatures above 10°C. After entering spring, gradually increase ventilation with warmer weather. Appropriate early exposing and late covering. To the cultivation period of open cultivation, we can not cover the grass curtain. After the minimum temperature in the outside world stabilized at 15°C, the footing film was lifted and ventilation was carried out day and night. 6. Fertilizer water management after the slow seedlings according to soil moisture. High-ridge cultivation of small water can be poured under the film 1 to 2 times, Pingshuo cultivated light water, and then the seedlings. Watering is done on a sunny morning. During seedling, 0.4% potassium dihydrogen phosphate is used for foliar fertilizer application, which is good for hair rooting. If the seedlings are too weak, foliar spray of sugar nitrogen solution (0.2% urea plus 1% glucose) has a good effect. After the door pepper sat, combined with watering for the first time dressing, per acre can be poured with the water pouring compost 2,000 tons of manure or 15 kg of ammonium nitrate and potassium 8 to 10 kg. After every 15 to 20 days, pour water once, according to the situation, every 2 to 4 times to chase the fertilizer, every 7 to 10 days after spring, pour water once, each time with water flushing fertilizer such as diammonium phosphate, urea, potassium sulfate and other fertilizers. Fertilizers should be used interchangeably. After the hot pepper enters the fruitful period, proper addition of carbon dioxide can significantly increase the yield of pepper. Topdressing carbon dioxide should strictly control the amount of use, application concentration and application time, the concentration is generally 550 ~ 750 mg / l, the amount of 0.18 ~ 0.98 kg per mu, application time should be grasped shortly after sunrise, 1 hour before ventilation to stop Application.
