First, seedbed selection. Pepper seedlings should be selected for high dryness, well-drained, well-ventilated and lightly-leaved soils with rich organic matter content. It requires 1-2 years without planting eggplant vegetables to prevent disease transmission. Seedlings are required to leave a seedbed at a ratio of 1:20. The seedbeds plowed the soil 1 week before sowing and applied 25 kg of high-efficiency compound fertilizer per acre. Seedlings are 1 meter wide and 40 cm wide. Seedbed finishing requirements under the rough loose, thin surface, flat, smooth.
Second, sowing. Sowing period is generally scheduled for mid-November. On the day of sowing, the seedbed was again quarried, finely ploughed and leveled, and the fertilizer was soaked and sowed. After sowing, it covers fine sand with a thickness of 3-4 times that of pepper seeds. Then it is covered with straw, and the straw is covered with a film. The membrane is firmly attached on four sides and can be moisturized, protected against rain, and protected against rodents.
Third, seedling management. When 1% of the buds are unearthed, the straw is removed and bamboo sheds are built. 70% of the buds have been unearthed, and a small amount of film is needed to remove the film. According to the weather conditions, the humidity will be lowered and the temperature will be reduced to prevent the formation of tall seedlings, while the spray root rot 300 times is used to prevent the knock-out of pepper seedlings. After the seedlings emerged, the seedlings were peeled off and the seedlings were planted. Four true leaves were planted as seedlings.
Fourth, points seedlings. After the seedlings are planted and survived, they gradually enter the cold season. The growth of pepper seedlings requires strict external environment. This requires the following four tasks:
1. The seedling sheds can use large, medium and small plastic sheds. The key is that the seedling sheds are required to have a strong skeleton and resist wind, snow pressure and rain. Shelf film is generally made of a new transparent plastic film of polyvinyl chloride or polyethylene.
2, bed soil should be loose and fertile, and requires no pathogens, pests and weed seeds. The soil with these excellent traits can be prepared as follows: vegetable garden soil 50%, compost 17%, bar or chicken manure 3%, pond mud 20%, plant ash 10%, pond mud to be used after drying and weathering. 40-50 days before seedling, the garden soil, fertilizer, pond mud and grass ash are prepared according to the proportion. Each 100 kg of culture soil is mixed with 1 kg of phosphate fertilizer and the amount of root rot is sterilized and sterilized, and the above materials are completely mixed. Stacking. During the stacking process, the proportion of 10 kg of livestock waste water poured per 100 kg of nutritious soil is poured while piling on one side. After the stacking is completed, it is closed with a plastic film, and it is stuffed with 20-30 days of boring.
3. When seedlings grow 4 true leaves, they are divided into seedlings, and the nutrients filled in the culture soil are discharged neatly. The width of the discharge is usually suitable for seedlings or management convenience. When transplanting seedlings, insert a small hard piece 1.5-2 cm deep in the middle of the nutrient bowl, separate the nutritious soil into a small hole, put the root of the seedling into the hole, and lightly press the soil. After the seedlings are well planted, watering will make the nutritious soil naturally tight. After a period of growing time, the weather is colder. It is better to cover the soil with insulation once again. The thickness is not suitable for nutrition.
Fifth, the whole seedling management technology points. (1) Ventilation and ventilation: Ventilation and ventilation: First, water droplets on the plastic film can be air-dried to increase the light transmittance of the plastic film. Second, the humidity in the greenhouse can be reduced to prevent the spread of diseases. (2) Disease prevention and seedling protection: Various pathogens are prone to breeding and spreading under high humidity conditions. In order to succeed in seedling raising in winter, under the premise of ventilation and dehumidification, regular spraying measures can effectively prevent dead seedlings. (3) Temperature control, water control and hormone regulation: The growth cycle of pepper seedlings is in winter, with early sowing and long seedling age. In case of winter high temperature, seedlings grow too fast, which may cause the connection between seedling time and field cultivation time, which can be taken as follows Measures: First, remove the film and reduce the shelf temperature; second, control watering; and third, spray 50% chlorpyrifos for 2000 times.
