Special cotton fertilizer produced by using biochemical fulvic acid through melt granulation and production method of special fertilizer

Abstract

The invention discloses special cotton fertilizer produced by using biochemical fulvic acid through melt granulation, relating to the technical field of special fertilizer of crop formula. The special fertilizer is obtained by taking 450-650 parts of nitramine phosphorus, 50-160 parts of potassium chloride, 80-300 parts of potassium sulfate, 50-150 parts of monoammonium phosphate, 1-100 parts of biochemical fulvic acid, 1-15 parts of EDTA (Ethylene Diamine Tetraacetic Acid) chelating zinc, 1-15 parts of EDTA chelating manganese, 1-20 parts of EDTA chelating iron, 1-20 parts of borax and 0.1-0.5 part of ammonium heptamolybdate as raw materials, mixing, stirring, heating, granulating, cooling and screening. The special fertilizer disclosed by the invention has the advantages of comprehensive nutrients, favorable water solubility, greenness, no pollution, high utilization rate, improvement on soil, increase of crop yield and improvement on quality.

Description

technical field [0001] The invention relates to the technical field of special fertilizer for crop formula, in particular to a special fertilizer for melt granulation biochemical fulvic acid cotton. Background technique [0002] Cotton is native to tropical and subtropical regions and is a perennial short-day crop. After long-term artificial selection and cultivation, it gradually moved north to the temperate zone and evolved into an annual crop, which can be divided into five stages: sowing stage, seedling stage, bud stage, flowering stage and boll opening stage. Cotton is not only a necessity for people's life, but also an important industrial raw material and military material. It plays an important role in the development of the national economy and has a large market demand. [0003] Studies have shown that for every 100 kilograms of lint produced, 10-18.5 kilograms of nitrogen and phosphorus (P 2 o 5 ) 3.5-6 kg, potassium (K 2 O) 13-16.5 kg, absorbing nitrogen, p...

AI Technical Summary

Problems solved by technology

[0005]1. Most of them are ordinary inorganic fertilizers. Long-term use will make the soil harden, weaken the soil fertility, and seriously damage the aggregate structure of the soil;

[0006]2. Uneven fertilizer nutrients;

[0007]3. The utilization rate of fertilizer is low, which easily causes the fixation and loss of nutrients, which not only wastes resources, but also easily pollutes the environment;

[0008] 4. Insufficient nutrition, generally does not contain boron, iron, zinc, manganese, molybdenum and other trace elements that can significantly improve cotton yield and quality, resulting in poor cotton yield high and reduced quality;

[0009]5. Fertilizers have poor water solubility and are not suitable for the integrated fertilization method of water and fertilizer which saves time and labor and greatly improves the utilization rate of fertilizers
