Pepper should be fattened. After transplanting and planting, apply 0.5 kg of diluted human excrement or urea per mu, combined with watering the seedlings for topdressing. During the growing period, top-dressing decomposed manure 1500 ~ 2000 kg or urea 7 ~ 10 kg per mu. After watering once, apply nitrogen fertilizer for the second time, and the amount of fertilizer applied is the same as the first time. After the full fruit period, combined with soil cultivation, apply organic fertilizer 1400 ~ 2000 kg or urea 15 ~ 20 kg per mu. Water the seedlings after cultivating the soil. In rainy season, in order to prevent fertilization after rain, urea 13 ~ 15 kg can be applied per mu.
Pepper should be well managed. After planting, water slowly to avoid excessive drop in ground temperature, which will affect slow seedling growth. Next, intertillage should be done in time to raise ground temperature and promote root growth. After seven days, water it for the second time. In order to prevent soil hardening, deep intertillage should be carried out with slightly shallow roots. Before entering the full fruit season, pay attention to watering, the soil moisture is good, and there is no need to water to avoid the growth of peppers. Keeping the soil moist during the full fruit period is beneficial to the continuous growth of plants and the flowering and fruit setting.
Secondly, talk about the problem of fertilizer. Usually we fertilize peppers three times. The first time is seedling fertilizer, which should be watered about a week after pepper is planted, preferably in a sunny afternoon. The second time is flower fertilizer, that is, it is poured in the period when pepper is about to bloom to meet the demand for nutrients for flowering and fruiting.
The third time is fruit fertilizer, which is usually applied after the first harvest of pepper. During this period, the plants entered the peak period of fruiting, and there was a great demand for water and fertilizer. If conditions permit, it is best to apply it once every harvest season, mainly potassium fertilizer and phosphorus fertilizer, and apply it in moderation.
The third is the word "defense". Prevention is to prevent pests and diseases. The prevention and control of pepper diseases and insect pests should adhere to the principle of prevention first and comprehensive control, and control pesticides with high efficiency, low toxicity and low residue. According to years of planting experience, pepper pests mainly include whitefly, red spider, aphid and so on. Therefore, it is necessary to prevent it early in prevention and control. Once found, it is necessary to apply drugs in time.
