1. Variety selection: Cultivation should use strong growth and disease resistance varieties. Zhongjiao No.2, Zhongjiao No.4 and Yunjiao No.2.
2, choose to do 畦, should choose fertile land, sunny leeward, the former 茬 did not plant pepper, eggplant, tomato plots do 畦. According to an acre seed amount of 150 grams for nursery.
3, scientific fertilization, Shizujifei: According to the demand in time to deepen the sun, soil disinfection, the commonly used disinfectants are Green Heng No. 1, No. 2, seedbed disinfection to prevent seedling disease. To raise the seedlings in the leeches, sifting 100-150 kg of rotten organic fertilizer and 1-1.5 kg of ternary compound fertilizer per 15 m2 of nursery bed, doubly mixing with the soil. Do not apply ammonium bicarbonate, sulfuric acid because the surface is sealed. Ammonium is used as a basal fertilizer to prevent ammonia from injuring the seedlings.
4, sowing, nursery: Shanghang general in February such as the use of greenhouses, plastic film covering seedlings can be sown. In order to raise the seedlings in the field, after the completion of the earthworms, fill the bottom water, fertilize and flatten the land, spread the seeds of sweet pepper evenly, cover 0.5 - 0.8 cm of fine soil, do not exceed 1 cm, increase the seedling emergence rate, and then cover the mulching film. Sealed with plastic film, control the temperature during the day about 25 °C, night 18 °C -20 °C. After 60% emergence, remove the plastic film, pay attention to moisturizing, and use a fine watering can to spray water evenly to increase the humidity, increase the intensity of photosynthesis, and protect the growth of seedlings.
Plastic seedlings are used. Preparation of nutritious soil: 50% of the fertile surface sandy loam soil not grown with eggplant vegetables, 50% of manure with decomposed sifting, 0.5-1 kg of NPK fertilizer per cubic meter, 50% carbendazim 80- 100 grams or green hen No. 5 grams. After mixing with good materials, the soil and fertilizer are fully mixed and then filled with nutrients, soaked in bottom water before sowing, and seeds that have been rushed through the seed are broadcast live.
5, seedling management: to avoid overcrowding seedlings, starting from the heart of 1 leaf, seedlings should be divided in time, between the seedlings, 3 leaves 1 heart Dingmiao, 5 cm from the hole to ensure that there is sufficient nutritional area. In 2-3 true leaves, 3-4 true leaves and 7-10 days before colonization, spray 0.2% potassium dihydrogen phosphate + 0.1% urea + 0.2% zinc sulfate mixed fertilizer solution to promote flower bud differentiation and Improve plant disease resistance.
