Early spring pepper cultivation techniques
First, nurture strong seedlings. Variety can be used Su Jiao No. 5, Su Jiao No. 6, Jiang Ye No. 2, Lian Jiao No. 1 and so on. The seeding period depends on the way of seedlings and the form of planting cover. Several different sowing forms in Huaibei: 1 Multi-layered cultivation. The cold bed is planted in the early September-October period, covering the form of plastic film + small arch shed + grasshopper + greenhouse, and is planted from the end of November to the beginning of December. A hotbed is planted in early December, covered with a cold bed, and planted in early February. 2 greenhouse cultivation. The cold bed was sown in early November and covered in the form of plastic film and greenhouse, and was planted in mid-March in the following year. The seedbed was sown in early January, covering the same form of cold beds and planted in mid-March. 3 small shed cultivation. The greenhouse nursery was sown in mid-January and covered in a single-story shed, which was planted in late March. Prepare a seedbed and soak the bottom water to sow. Sowing 6-8 grams per square meter, 50-75 grams per mu of field need to be planted. Seed bed temperature before seedling emergence is about 30°C during the day and about 20°C at night. When 50-60% of the seedlings are unearthed, the bed surface mulch film will be removed timely. After Qimiao, it is necessary to control the temperature, moisture and light, prevent leggy, 25 °C during the day, 18 °C at night, and do a good job and time seedlings, seedlings work. Second, rational dense planting. When the temperature in the shed is 10 centimeters stable above 12 degrees Celsius, it can be planted and covered in multiple layers. The time for planting is before and after the Spring Festival. Other simple covering methods will delay the time for planting. The rooting water is poured through the side of the planting. The density of colonization varies from species to species, with about 4500 strains per mu. Third, field management. After planting, pre-heat insulation and anti-freezing work shall be done well, and light reduction and cooling work shall be done later. Before the pepper is set in the door, it is generally not easy to water, and in the future, watering in conjunction with top dressing is required, and a large amount is gradually added. Top dressing is organic manure, phosphorus and potash fertilizers. Fruits should be timely additional fertilizer. For each harvest twice, topdressing 1 time, applying 10-15 kilograms of urea per acre. Fourth, the harvest of the commodity fruit. The listing of fresh peppers is not strictly required for maturity, as long as the fruit is fully inflated, the fruit table has a certain degree of gloss can be harvested. When the peppers enter the full fruit period, they must be harvested and diligently harvested, usually harvesting every 2-3 days. Fifth, pest control. The main pests are viral diseases, anthrax, epidemics, damping-off, and locusts. The prevention and treatment of pests and diseases should be based on prevention, integrated field management and chemical control combined as a principle.
