"Three fats" deep principles
Fertilizer deep application technology includes deep application of base fertilizer, deep application of seed fertilizer and deep application of topdressing fertilizer. Basic fertilizer application Before sowing and planting, the fertilizer applied to the soil can be called base fertilizer (or base fertilizer). Its role is to fertilize, improve soil, and improve soil fertility; the second is to provide nutrients for the entire growth period of a crop. Fertilizers used as basal fertilizers mainly include organic fertilizers and chemical fertilizers. Fertilizers are mainly nitrogen, phosphorus and potash fertilizers. Dosage: Organic fertilizer (containing more than 8% organic matter) is better than 30 tons per hectare. Chemical fertilizers generally use 80% to 90% of the pure nutrient content of phosphorus and potassium fertilizer and 20% to 30% of the total amount of nitrogen. Base fertilizer applied. Deep application method: First, in combination with deep soil preparation, the above organic fertilizer is dispersed and thrown into the soil, and nitrogen, phosphorus, and potassium fertilizers can be mixed with a certain amount of organic fertilizer, and then applied in the ridging process. The method is applied deep into the ridges; the second is the use of Sanlichuan to apply basal basal fertilizer at a depth of 15-18 cm. Fertilizer application When sowing, the fertilizer applied near the seed (or seeded with a certain concentration of fertilizer solution) is called seed fertilizer (or mouth fat). The role of seed fertilizer is mainly to supply nutrients to the seedlings of the crops and promote the growth of seedlings; secondly, to improve the physiochemical traits and microbial activity of the seed beds. The main fertilizers used as seed fertilizers include refined organic fertilizers, 10%~20% nitrogen fertilizers, and phosphorus and potassium fertilizers equal to nitrogen. Fertilizer for seed fertilizer, it is appropriate to 3 to 6 cm from the seed, and the best with the application of refined organic fertilizer, so as not to affect the seed germination and emergence. Fertilizer deep application can be used monomer seeder, with the planting with fertilizer, planted on the top, fertilizer in the next, to achieve seed fertilizer isolation, fertilizer deep application purposes, its fertilization depth of up to 10 cm. Top dressing Top dressing is the application of fertilizer during the growth of the crop, mainly the base fertilizer and 60% of the remaining nitrogen fertilizer after the seed fertilizer, its purpose is to meet the nutrient requirements during the crop growth period. Fertilizers should catch the key period of top-dressing, such as combining wheat with trifoliate water, corn, sorghum and millet in the jointing period, soybeans in the early flowering period, and early recovery and deep application. Can use mechanical dressing device machine to promote deep furrow fertilizer technology, to achieve the purpose of deep fertilization.
