Abstract

The invention discloses special slow-release bulk blending fertilizer for wheat and a preparation method of the fertilizer. The special slow-release bulk blending fertilizer for wheat is mainly prepared from components in percentage by weight as follows: 16%-18% of resin coated urea granules, 4%-6% of urea particles, 39%-41% of diammonium phosphate granules, 14%-16% of resin coated potassium nitrate granules, 4%-6% of potassium chloride granules, 10%-13% of anhydrous calcium chloride granules, 7%-10% of magnesium sulfate monohydrate granules, 0.4%-0.5% of zinc sulfate monohydrate granules, 0.2%-0.3% of boric fertilizer granules and 0.2%-0.3% of additive granules, wherein the mass ratio of available nitrogen to slow-release nitrogen is (1-1.1): 1, and the mass ratio of available potassium to slow-release potassium is 1: (3-1.4). The special slow-release bulk blending fertilizer for the wheat is prepared on the basis of soil nutrient characteristics in Shanghai area, adopts the reasonable and comprehensive nutrient proportion, facilitates absorption and utilization by the wheat, can improve the soil granular structure, improve root system activity and soil fertility, promote the wheat to grow robustly and increase the fertilizer utilization rate and is convenient to use, the preparation process is simple, the fertilizer is efficient, low in consumption, low in cost, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of novel slow-release fertilizers, in particular to a special slow-release blended fertilizer for wheat and a preparation method thereof. Background technique [0002] At present, the traditional fertilizer industry is in a downturn, and new fertilizers are getting more and more attention, and have become a "sharp weapon" for many fertilizer companies to deal with market difficulties. my country's new fertilizers are roughly divided into four categories: slow / controlled release fertilizers, biological fertilizers, multifunctional fertilizers, and synergistic fertilizers. Slow / controlled release fertilizers can be divided into two categories according to the principle of nutrient release: one is to control the dissolution process of nutrients, so as to control the dissolution rate of nutrients into the soil, which is beneficial to the absorption and utilization of nutrients by crops, such as chemically synthe...
