This kind of vegetable should be a non-polluting, safe and nutritious green product. In the fertilization technology, it is necessary to apply organic fertilizer, supplemented by multi-component compound fertilizer, and disable industrial waste, urban domestic waste and sludge and sewage. Mud, to prevent the application of urea, ammonium nitrate and other nitrogen fertilizers. The fertilizer requirement and fertilization techniques of pollution-free peppers are described below.

The fertilizer requirement of pepper

The amount of nutrients such as nitrogen, phosphorus and potassium absorbed by pepper in different growth stages varies from seedling to bud. Because the roots of the plant are small and the dry matter accumulates slowly, the nutrients needed are less. It accounts for about 5% of the total amount of absorption; from the bud to the initial growth of the plant, the vegetative body expands rapidly, the dry matter accumulation also increases gradually, and the absorption of nutrients increases, accounting for about 11% of the total absorption; The result of flowering to full bloom is the period of vegetative growth and reproductive growth of pepper, and it is also the period of absorption of nutrients and nitrogen, accounting for 34% of total absorption. From full bloom to maturity, the vegetative growth of plants is weak, then phosphorus, Potassium is the most needed, accounting for about 50% of the total amount of absorption; after harvesting of mature fruit, in order to promote the growth and development of branches and leaves in time, a larger amount of nitrogen fertilizer is needed.

Capsicum fertilization technology

According to the fertilizer requirement of pepper and the soil fertility, the base fertilizer is first applied. In the various stages of pepper growth and development, according to the requirements of 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: excavating the soil from the ground where the solanaceous vegetables and tobacco have not been planted in the past three years, preferably using the topsoil of onion, celery or cereal crops, excavating as early as possible, drying and breaking, using 10 The millimeter sieve is sieved and stored; the fully cooked manure is used, and the sieved storage is broken. 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 10-15 kg of ternary compound fertilizer per mu, chasing and watering; harvesting period should be chased and rushed, and chasing a manure manure every 5 to 6 days in the sunny day, in the 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, and generally increasing yield by more than 10%. Spraying 0.1%-0.2% borax aqueous solution during flowering period can increase the fruit setting rate. It can spray 0.3%-0.4% potassium dihydrogen phosphate solution in the whole growth period, 50 kg per mu spray liquid fertilizer. It is advisable to apply the foliar fertilizer no more than 15 days before harvesting.
