Pepper should become pollution-free, safe and nutritious pollution-free vegetables. In the fertilization technology, it is necessary to apply organic fertilizer mainly, supplemented by multi-component compound fertilizer, and ban industrial waste, urban domestic waste and sludge and sludge discharged from sewage. The application of nitrogen fertilizers such as urea and ammonium nitrate is eliminated. ——Editor needs fertilizer regular peppers in different growth stages, the amount of nitrogen, phosphorus, potassium and other nutrients absorbed are also different, from emergence to bud, because the roots of the plant are small, the dry matter accumulation is slow, so The nutrients needed are also small, accounting for about 5% of the total amount of absorption; from the bud to the initial flower plant growth, the vegetative body is rapidly expanding, the dry matter accumulation is gradually increasing, and the absorption of nutrients is increased, accounting for the total amount of absorption. 11%; the result from the initial flower to the full bloom is the period of vegetative growth and reproductive growth of pepper, and also the period of absorption of nutrients and nitrogen, accounting for 34% of total absorption; from flowering to maturity, the vegetative growth of plants is weak. At this time, the demand for phosphorus and potassium is the most, accounting for about 50% of the total amount of absorption; after harvesting the mature fruit, in order to promote the growth and development of the branches and leaves in time, a larger amount of nitrogen fertilizer is needed.
According to the fertilization requirement of pepper and the fertility of soil, the fertilization technique first applies the base fertilizer. In each period of pepper growth and development, according to its requirements for nutrients, different types and quantities of fertilizers are applied to carry out scientific topdressing. Do "one control, two promotion, three insurance, four bogey". One control is to control fertilization during flowering period, so as to avoid falling flowers, deciduous leaves and fruit drop; the second promotion is that the young fruit period and the harvesting period should be topdressed in time to promote the rapid expansion of young fruit; the three guarantees are guaranteed not to be fattened, not long, not
Fertilized; four bogey is to avoid using high-concentration fertilizer, avoid wet soil topdressing, avoid high temperature when topdressing, avoid too concentrated after topdressing.
1. Nursery to prepare high quality culture soil. The preparation method: the soil is excavated from the ground where the vegetable and tobacco have not been planted in the past three years, dug out as soon as possible, dried and broken, and sieved with a 10 mm sieve; the fully decomposed manure is used and broken. Screen storage. The sieved soil was blended in a ratio of 1:3 before seedling. In addition, 1 kg of calcium phosphate, 20 kg of ash, and 0.5 kg of diammonium phosphate are applied per 1000 kg of culture soil.
2. Fertilization in Daejeon. (1) Applying the base fertilizer: This is one of the effective measures to promote the growth of the seedlings and accelerate the high yield of the peppers. It should be based on organic fertilizer, and should be fully decomposed to reduce the introduction of pathogenic bacteria and eggs. Before the ploughing, the per-mu application or ditch application is fully decomposed with high-quality farmyard manure 5000 kg, diammonium phosphate 30 kg, and grass ash 100 kg. (2) Scientific topdressing: the first topdressing can be carried out during the young fruit period, and 1,500 kilograms of manure and urine are applied per acre. If there is no rain after topdressing, watering can be done; if the growth is not good, the fruiting period should be carried out in the fruiting period. Secondary topdressing, applying tens of ternary compound fertilizer per mu to 10 kg to 15 kg, chasing after watering; harvesting period should be chased and rushed, and chasing a manure manure every 5 to 6 days in the sunny day, in the early morning or evening Watering and topdressing is good. (3) Foliar spray fertilizer: its advantages are small dosage, high absorption rate, fast effect, increased chlorophyll content and photosynthesis intensity, which is conducive to the accumulation of organic matter, preventing falling flowers and falling fruits.
The general yield increase is above 10%. Spraying 0.1%-0.2% borax aqueous solution during flowering period can increase the fruit setting rate, and spray 0.3%-0.4% potassium dihydrogen phosphate solution for several times in the whole growth period. About 50 kg is suitable, no more foliar fertilizer is applied 15 days before harvesting.
