Abstract

The invention provides a special inorganic compound fertilizer for wheat, which is composed of the following raw materials in parts by weight: 30-40 parts of urea, 15-25 parts of monoammonium phosphate, 14-18 parts of potassium chloride, 5-10 parts of ammonium chloride, 4-5 parts of sodium selenite, 2-3 parts of compound sodium nitrate, 3-4 parts of polyacrylamide, 4-5 parts of alumen powder, 3-4 parts of zinc sulfate, 2-3 parts of sodium borate, 2-9 parts of adhesive and 3-7 parts of acidity regulator. The beneficial effects are as follows: the special inorganic compound fertilizer for wheat is rational in component matching, simple in preparation process, high in practicability and capable of satisfying requirements of wheat growth on various nutritional elements such as nitrogen, phosphorus and potassium; and the increasing of wheat yield is facilitated.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special inorganic compound fertilizer for wheat and a preparation method thereof. Background technique [0002] Wheat is one of the most important crops. It contains starch, fat, protein, vitamins, calcium, iron and other nutrients needed by the human body. The level of wheat production directly affects the income of farmers and the supply of flour throughout the country. In recent years, the yield per mu of wheat has continued to increase, but the common problems are high input costs, low output benefits, and failure to increase farmers' income. [0003] Fertilizer is a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility. There are many types of fertilizers, and different crops have different requirements for fertilizers due to their different growth habits and growth stages...
