Long-acting total-nutrient wheat special-purpose fertilizer suitable for straw turnover, and processing method thereof

Abstract

The invention discloses a long-acting total-nutrient wheat special-purpose fertilizer suitable for straw turnover. The long-acting total-nutrient wheat special-purpose fertilizer suitable for straw turnover is composed of, by weight, 400 to 550 parts of urea, 150 to 300 parts of potassium chloride, 200 to 300 parts of monoammonium phosphate, 1 to 10 parts of inhibitor NAM, 1 to 10 parts of boric acid, 1 to 10 parts of EDTA chelated zinc, 1 to 10 parts of EDTA chelated copper, 1 to 10 parts of EDTA chelated manganese, 1 to 10 parts of EDTA chelated iron, 0.1 to 0.4 part of ammonium heptamolybdate, and 0.1 to 0.4 part of a bacterial preparation. The long-acting total-nutrient wheat special-purpose fertilizer possesses following advantages: 1, the appearance is smooth, caking is not easily caused; 2, nutrient combination is balance, and stable; 3, fertilizer effect lasts long, utilization rate is high, labor intensity is reduced, and environment pollution is reduced; 4, nutrients are comprehensive; and 5, the bacterial preparation is contained.

Description

technical field [0001] The invention belongs to the technical field of fertilizer specially formulated for crops, and in particular relates to a special fertilizer for long-acting full-nutrition wheat suitable for straw returning to the field and a preparation method thereof. Background technique [0002] Wheat is the general designation of wheat plants, is a monocotyledonous plant, is a kind of gramineous plant widely planted all over the world, and the caryopsis of wheat is one of the staple foods of human beings. [0003] Wheat is one of the three major grain crops in China. The planting area accounts for about 22% of the total area of ​​grain crops, and the output accounts for more than 20% of the total output of grain crops. It is the main commodity grain and strategic reserve grain variety in my country. It plays an important role in consumption, and the development of wheat production and improvement of wheat quality are of great significance to the development of my c...

AI Technical Summary

Problems solved by technology

[0008] 1. Most of them are ordinary inorganic fertilizers, which generally do not contain biological bacteria that can improve the soil microbial environment and promote straw maturity; if used alone, it will take time and effort;

[0009] 2. The fertilizer has high moisture content, is easy to harden and pulverize, and has poor nutrient uniformity;

[0010] 3. The fertilizer effect is short and the utilization rate is low, which is easy to cause nutrient loss and later defertilization;

[0011] 4. Insufficient nutrition, generally does not contain trace elements such as boron, zinc, iron, copper, manganese, molybdenum required for wheat growth, resulting in low yield and quality decline of wheat
