Dedicated wheat fertilizer with characteristic of disposable fertilization

Abstract

The invention relates to dedicated wheat fertilizer with the characteristic of disposable fertilization, the problems of fertilizer for wheat planting that second pollution cannot be prevented, and the cost is expensive can be effectively solved. The dedicated wheat fertilizer is characterized by being prepared from the following raw materials in percentage by weight: 13 to 25 percent of urea, 16to 39 percent of ammonium chloride, 18 to 22 percent of monoammonium phosphate, 8 to 10 percent of potassium chloride and 18 to 30 percent of clay mineral granule controlled release agent. The dedicated wheat fertilizer is prepared through the following steps: mixing the urea, ammonium chloride and the clay mineral controlled release agent together, thus preparing a material A; mixing potassium chloride with the material A, thus preparing a material B; uniformly mixing monoammonium phosphate with the material B, thus preparing granules; drying and sieving the granules, and enabling the granules of which the granularity is 3.35 to 5.6 mm to be up to 90 percent or above, thus obtaining a finished product. The dedicated wheat fertilizer disclosed by the invention has the characteristic of realizing one-season fertilizer supplying through single fertilization, not only can good nutrient elements be provided for wheat, but also the demands on nitrogen fertilizer during a whole growth periodof the wheat can be met, raw materials are rich, the preparation method is simple, the cost is low, a using effect is good, the dedicated wheat fertilizer can be effectively used for planting the wheat, and high yield and good harvest are ensured.

Description

technical field [0001] The invention relates to agriculture, in particular to a special fertilizer for wheat with the characteristics of one-time fertilization for agriculture. Background technique [0002] It takes up to 200-240 days for wheat to mature from emergence, tillering, jointing, booting, heading, flowering, filling to maturity. It has a large and long-lasting demand for nutrients. If high-quality and high-yield is to be obtained, conventional fertilization methods must be fertilized multiple times. High cost and low efficiency, extremely difficult to operate; [0003] The use of chemical fertilizers is high and the pollution is serious. Although a large number of coated slow-release fertilizers developed at home and abroad can control the release of nutrients to a certain extent, most of the coating materials such as resin are generally difficult to degrade by themselves, causing soil secondary pollution. Pollution and the high price of coated fertilizers limit ...
