The selection of good seedlings in winter and spring pod cultivation is early maturing. It is necessary to pay attention to the early maturity of the varieties, taking into account the high yield and disease resistance. Suitable varieties include Hong Ying Da, Andalai, and the Holy Ark. In addition, the Bulgarian sharp pepper, the Su Jiao No. 5 and so on.

Site preparation fertilization applies 100,000 kg of high-quality manure or compost per acre, 25 kg of urea, 50 kg of diammonium phosphate and 100-200 kg of cake fertilizer. These base fertilizers should be applied according to different colonization methods. Peppers can be planted flat or ridged. For the convenience of coating and watering, as well as to help improve the ground temperature, it is recommended to use ridges in the north-south direction. When ridges are planted to determine the ridge distance, they must be different for each cultivar, and the row spacing should be determined according to the opening angle of the cultivar used. In winter and spring, more than one plant should adopt the method of dense planting of one planting a pair of aphids. Large row spacing 55~60 centimeters, small row spacing 40~50 centimeters. When fertilizing, first spread the organic fertilizer on the ground and deep-dip twice to fully mix the fertilizer and the soil, then open the ditch by row spacing, apply the cake fertilizer and chemical fertilizer in the ditch, mix thoroughly with the soil, and then furrow on the ditch. The ridge height is 15-20 centimeters.
Scientific planting and colonization must be selected on sunny days, and it is expected that they can encounter consecutive sunny days after planting. This will require more listening and watching more weather forecasts. Colonization should take place in the morning. When planting, press the hole about 33 cm to open the hole. About 4,000 holes per acre, 2 per hole, 8,000 per acre, with dense planting for early production. 2 strains in the same cave have the same size. When the seedlings were planted, they were poured with warm water (30~40°C) and seedlings were planted, and the water was infiltrated and then sealed.
Before planting strong seedlings, pepper seeds should be soaked in 10% trisodium phosphate solution for 30 minutes. In order to prevent anthrax and bacterial spot disease, it can be pre-soaked with fresh water for 5~6 hours, then put in copper sulfate solution for 5 minutes, then washed with clean water and then germination. In order to cultivate strong seedlings, it is best to use electric heating lines for seedlings. When the seedlings grow two true leaves, the seedlings are subdivided once and the seedlings are transplanted into the nutrient pods, one for each worm, and placed on the electric wire nursery bed. The daytime temperature during the seedling period is maintained at 28-25°C.
Post-plant management 1 is planted until harvested. 5 to 7 days after planting is a slow seedling period, this time to seal the greenhouse, try not to ventilate. The temperature during the day can exceed 30°C. Insulate as much as possible during the night and try to reach 18~20°C. At the same time should always check, pay attention to make up at any time. After easing the seedlings, they should pour water into the ditch and then control the water. When flowering, apply a flower stalk with 2,4-D from 20 to 3010-6. The old leaves of the main stem are removed in time to promote lateral branch growth. 2 Early harvest to harvest. This period is a critical period for the production of pepper. Temperature plays an important role in flower quality and fruit enlargement. The daytime temperature is maintained at 25~30°C, and the nighttime temperature is maintained at 15~20°C. If the nighttime temperature is above 20°C, the fruit enlargement will be accelerated, but the plants will begin to decline; when the nighttime temperature is below 15°C, it will be unfavorable for fruit growth, even "Strange fruit" appears. Light is important for photosynthesis, so you must pay attention to cleaning the film surface. At the same time to adjust the plant, increase light transmission. The required relative humidity of pepper is 60% to 80%. When the humidity is low, it is not good for photosynthesis. The soil should be kept moist, but it should not be seen only on the ground. Special attention should be paid to the deep soil moisture content, which should generally be about 70% to 80% of the maximum water capacity in the field. When you combine top dressing with water, you can't just use nitrogen fertilizer, you must use nitrogen, phosphorus, and potassium fertilizers. Usually about 30 days, about 25 kg per mu.
As a result, the plants tend to age after the harvest period at the later stage of management. Management should be based on sustaining growth, not water shortages and lack of fertilizers. Top dressing should be dominated by nitrogen and potassium fertilizers, and the combination of top dressing and watering should be done. When the amount of air is large, 25 kg/mu of ammonium nitrate can be poured into the water to maintain the growth of the later period and extend the result period. When exposed to daytime and nighttime temperatures are stable above the optimum temperature for pepper growth, the film can be removed and transferred to open field production.
The major diseases of insecticide-resistant pepper pests are powdery mildew, anthrax, soft rot, scab, and viral diseases. Insect pests mainly include aphids and whiteflies, and they should be given time to prevent and control them.
Harvesting at the right time usually takes 40 to 50 days to start harvesting. Peppers and peppers should be harvested as early as possible to avoid affecting plant growth. When harvesting, it is best to cut fruit in order not to damage young shoots.
