The "Five Excellent" Cultivation of Pepper in Autumn

Variety selection is suitable for varieties cultivated in late autumn must be early high temperature resistance, late low temperature resistance, strong disease resistance, the results of the more concentrated, fast growth, fruit type, full, beautiful shape, to early maturity of the fine varieties For excellence, such as Xiangyan No. 9, Xiangyan No. 12, and Sujiao No. 5, etc.

The sowing date selection is mainly based on the best listing period. After the middle and lower reaches of the Yangtze River in November, due to the rapid decline in temperature and the advent of frost, it is not suitable for the normal growth and development of ground-growing cultivars. The fruit that has been sitting may be completely destroyed by frost overnight. Therefore, at this time, the peppers enter a marked off-season and the price is high. After the late autumn cultivation of the greenhouse, it can not only guarantee the supply of peppers during the period, but it can also be delayed until the New Year's Day and the Spring Festival. The output value per mu can reach 5,000 to 6,000 yuan.

The method of selecting seedlings is preferred because the pepper seedbed is in a period of high temperature after the fall, so the postponed cultivation of the greenhouse should use the method of exposing the seedlings outside the shed or in the shed. If we do not use cooling measures such as covering the shade net, the virus disease will be particularly serious. In view of this, strict nursery measures shall be taken for the nursery in the greenhouse or the nursery outside the greenhouse. The formalin solution was sprayed on the seedbed 10 days before planting, and 50 g/m2 was sprayed. Immediately after spraying, the cover film was steamed for 2 to 3 days, then the film was uncovered. The film was sown only 7 days after the film was uncovered; the seeds were soaked in fresh water for 8 hours before sowing, and the seeds were then soaked in 10% trisodium phosphate solution for 20 to 30 minutes. Wash directly after sowing. Water immediately after sowing and cover it with a shade net. Depending on whether the soil is wet or dry, pour water 1 or 2 times in the morning or evening. After 90% of the seeds broke the buds, the shade nets were removed and the seedlings were planted with 3 to 4 leaves. Sunscreen should pay attention to sunny cover, cloudy exposing; sunny morning cover, evening exposing. Pepper seedlings 8 to 10 true leaves when planting.

Optimum temperature adjustment measures Pepper is thermophilic but not heat-tolerant. After planting until late September, shade nets should be covered in the greenhouses and capping methods should be adopted. The shade nets should be removed from early October to mid-November. When the night temperature is below 15°C, cover the shed film to keep warm, cover during the day and cover at night; after mid-November, the small shed in the greenhouse should be set up in time, cover the agricultural film, exposing during the day, cover at night; if there is frost weather , can use straw cover to keep warm.

After optimizing fertilizer and water management for a period of time, it is necessary to adopt a method of furrow irrigation to reduce moisture. To prevent defoliation, high-temperature fertilizers should not be applied to manure, use 45% compound fertilizer, 7 to 10 kilograms per acre, with 0.3% to 0.5% concentration of liquid shower. To reduce the number of irrigation after the beginning of October; after a large number of fruiting, each acre applied 30% of human excrement urine 1000 ~ 1500 kg, plus potassium chloride 5 ~ 8 kg, promote fruit enlargement.
