Problems solved by technology

Due to the large amount of organic fertilizer used per unit area, coupled with insufficient supply, the deterioration of soil quality caused by chemical fertilizers is difficult to overcome in my country in the short term
In addition, many patents or technologies in the production of compound fertilizers did not take into account the conversion and solidification of soil to various fertilizers, especially phosphate fertilizers and micro-fertilizers. They simply mixed various nutrients together, making it difficult to maximize exert their nutritional function

Abstract

The invention relates to a fertilizer, and concretely relates to a multielement nutritious fertilizer. The multielement nutritious fertilizer is characterized by being composed of the following elements: nitrogen, phosphorus, potassium, and trace nutritious elements iron, zinc, copper, manganese, magnesium, boron, molybdenum, bromine, iodine, cobalt and strontium, a cosolvent citric acid, an anti-caking agent dehydrated alum, a functional additive chitosan, fly ash, pyrite slime and kaolin. The advantages comprise that the formula has extremely strong pertinency on soil and plant growth, and thus the fertilizer relatively fully gives play to fertilizer efficiency, furthest satisfies demands of crops on fertilizers and trace nutrition, increases output of crops, and helps to improve soil granular structure, improve soil water-retention performance, inhibit and kill underground insect diseases and the like.

Description

[0001] technical field [0002] The invention relates to a chemical fertilizer, in particular to a multi-element nutrient chemical fertilizer. Background technique [0003] Fertilizer is an indispensable nutrient for plant growth. The absorption of fertilizer by plants is not only related to the structure of the fertilizer itself, but also closely related to the aggregate structure of the soil. Long-term use of chemical fertilizers alone will cause soil compaction, decreased aeration, poor water retention and drainage, and the fertilizer effect will disappear too quickly and the effect will not be prolonged. Chemical fertilizers can also cause soil biological populations to change in ways that are unfavorable to crop growth, sometimes when some crops are susceptible to virus damage and die during continuous cropping. Due to the large amount of organic fertilizer used per unit area, coupled with insufficient supply, the deterioration of soil quality caused by chemical fert...
