Problems solved by technology

Because the raw materials are easy to produce insoluble substances such as calcium salts and magnesium salts after being melted at high temperature on the tower, it brings certain difficulties to the preparation of high-tower water-soluble fertilizers. The prepared fertilizer has more than 6% water-insoluble substances and a lot of residue

Abstract

The invention discloses a wheat special fertilizer and a preparation method thereof. The fertilizer comprises, by weight, 40-70 parts of nitrogen containing fertilizer and 35-60 parts of solid fertilizer, wherein the solid fertilizer comprises macroelement fertilizer, secondary element fertilizer and microelement fertilizer with the weight ratio of being 32-50:1-5:0.2-1, and the macroelement fertilizer comprises nitrogen fertilizer, phosphate fertilizer and potassic fertilizer with the weight ratio of being 13-24:17-26:0-16. The wheat special fertilizer has the advantages that through a scientific formula and reasonable proportioning, the absorbing and converting of nutritious substances of plants can be accelerated, the stress resistance, drought resistance and cold resistance of crops can be significantly improved, and the yield is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and in particular to a special fertilizer for wheat and a preparation method thereof. Background technique [0002] The growth of crops is increasingly dependent on chemical fertilizers, and its role is becoming increasingly prominent. At the same time, there are currently too many or too few applications of nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer, which not only cannot effectively utilize the fertilizer efficiency of crops, but also has a certain impact on the ecological environment. [0003] Wheat base fertilizer is an important measure to improve soil fertility in wheat fields. The amount of wheat base fertilizer should account for about 60-70% of the total fertilizer amount. The base fertilizer is mainly nitrogen and phosphorus. The base fertilizer can ensure the nutrient needs of wheat seedling growth, promote early growth and rapid growth, so that the whe...
