L-shaped multifunctional liquid micro-fertilizer with organic active substances and preparation method of micro-fertilizer

Abstract

The invention discloses an L-shaped multifunctional liquid micro-fertilizer with organic active substances and a preparation method of the liquid micro-fertilizer. The liquid micro-fertilizer comprises, by weight, 40-60 parts of urea, 180-220 parts of potassium humate, 15-25 parts of potassium dihydrogen phosphate, 40-60 parts of potassium nitrate, 4-6 parts of boric acid, 90-130 parts of ammonium polyphosphate, 310-350 parts of urea ammonium nitrate, 20-30 parts of wetting agents and 700-900 parts of water. The preparation method includes the steps: firstly, adding 50-70% of water into a reaction kettle; secondly, adding, stirring and dissolving the potassium humate, and adding the urea ammonium nitrate and the ammonium polyphosphate until complete dissolution; continuing to add and stir the potassium dihydrogen phosphate, the potassium nitrate and the boric acid until solution is clear; adding the wetting agents; finally, adding the rest water to meter volume, and uniformly stirring mixture to obtain the L-shaped multifunctional liquid micro-fertilizer. The liquid micro-fertilizer is simple in production process, high in nutrient content and utilization rate and reasonable in nutrient formula, high yield and high quality of crops are remarkably facilitated, economic benefits are improved, and the negative of improper application of nitrogen fertilizers on environments is decreased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an L-shaped multifunctional liquid micro-fertilizer containing organic active substances and a preparation method thereof. Background technique [0002] As a large agricultural country, agricultural production plays a vital role in my country's national economy and social stability. Fertilizer is an important means of production in agricultural production, and its contribution rate in the process of increasing crop production exceeds 40%, which is the key factor affecting agricultural crop production. and quality factors. At present, solid fertilizers are widely used. Due to the poor water capacity of solid fertilizers, more than half of the fertilizer residues are easy to cause environmental pollution, resulting in soil compaction and soil fertility decline; at the same time, the quality of agricultural products is reduced, and the ability to resist diseases and insect pests ...

Problems solved by technology

At present, solid fertilizers are widely used. Due to the poor water capacity of solid fertilizers, more than half of the fertilizer residues are easy to cause environmental pollution, resulting in soil compaction and soil fertility decline; at the same time, the quality of agricultural products is reduced, and the ability to resist diseases and insect pests is reduced. , it is difficult to produce high-quality and high-yield

[0003] In order to solve many problems existing in solid fertilizers, liquid multi-functional organic fertilizers have become the main trend in the development of fertilizers. However, most liquid fertilizers currently on the market have their own defects, such as low nutrient content and prone to crystallization and precipitation.
