First, sowing. In early March, sowing, electric greenhouse nursery for greenhouses, double membrane coverage, bed soil in addition to the appropriate amount of decomposed compost (generally fine soil and compost ratio of 4-5:1), before sowing to be added in bed soil 10%-15% of the plant ash and 0.5%-1% of superphosphate in order to facilitate emergence and strong seedlings. Seedlings 2 leaves before the temperature control in the greenhouse at 25-30 °C, 2 leaves after the temperature is controlled at 20-25 °C, to prevent prosperous. Bed soil whitening to replenish water in a timely manner. About 45 days after sowing, the seedlings are divided and seedlings are planted within 7-10 days to promote hair roots and live trees. Generally, small sheds set inside sheds are not to be stripped, so that the temperature in the sheds is maintained at 30-35°C, and the sheds are generally not ventilation. After the plants lived, the temperature in the greenhouse was maintained at 25°C.

Second, transplanting. According to the early stage of the nursery period, the colored pepper seedlings can be transplanted from late March to early April. Due to the large individual growth of color pepper, it is necessary to plant a single plant, and the row spacing is larger than the ordinary big pepper, generally 0.5-0.6 meters 0.6-0.8 meters. After transplanting, the rooting water is poured and covered with a plastic film.

Third, shelter from the rain. Compared with the conventional pepper, the color of the big pepper is very weak disease resistance, planted in the southern region, due to rain causes more disease. Therefore, the color of large peppers need to avoid rain cultivation. In early May, according to the air temperature during the day, it is humid and humid, and the shed is closed at night; in the middle and late May, the skirt film is removed, leaving only the top film to shelter from the rain.

Fourth, fertilization and pest control. The big color peppers are applied to the basal fertilizer once before transplanting, and generally do not be top-dressed in the later period. Each mus of the decomposed chicken manure is 1500 kg and the 45% BB fertilizer is 30-40 kg. Support a ditch system to prevent water accumulation in the shed. The diseases and pests that injure the color peppers mainly include anthrax, epidemics, gray mold, virus diseases and aphids. Control methods: Before sowing, 50 g of 25% carbendazim WP is mixed with bed soil to prevent and control seedling stage. Disease. After transplanting, it was treated with imidacloprid and 20% virus A500 times to prevent virus diseases and aphids 1-2 times. 70% thiophanate-methyl wettable powder 600 times, 50% fast-inking wettable powder 1500 times, respectively, to control anthrax and gray mold. Some color pepper varieties such as the Beijing Color Star series and the multi-colored angel series of red, yellow and other varieties, in the fruit color change period (the initial fruit is green, the outcome of the period into color) to strengthen the prevention of disease.
