Water-soluble fertilizer using amino acid-microelements chelate

Abstract

The invention discloses a water-soluble fertilizer using amino acid-microelements chelate. The fertilizer comprises an absorption enhancer, a fertilizer substrate and a microelement fertilizer. The fertilizer substrate is composed of urea and plant ashes. The mass ratio of the urea and the plant ashes is 20:80, the absorption enhancer is gibberellin, and the mass ratio of the fertilizer substrateand the absorption enhancer is 1000:1. The preparation method of the microelement comprises the steps of placing a protein raw material in a reaction pot, adding 5mol / L of hydrochloric acid, wherein the proportion of the protein raw material and the hydrochloric acid is 1kg:10L, hydrolyzing at 60-70 DEG C temperature for 6-10 hours, and after the hydrolyzing is completed, neutralizing sodium hydroxide and the remnant hydrochloric acid to obtain a compound amino acid water solution. The water-soluble fertilizer using amino acid-microelements chelate is low in cost, easy in operation and production, can enables accurate control of the mass ratio of the microelements, has high use ratio of the microelements, is easily absorbed by plants, does not harm human body and plants, and does not pollute lands.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a water-soluble fertilizer using amino acids to chelate trace elements. Background technique [0002] After entering the 21st century, with the development of modern agricultural production, people are looking forward to the emergence of multi-functional fertilizers in the field of fertilizers, which can improve the soil, improve the quality of crop yields, increase production efficiency, reduce production or improve labor conditions, protect The natural environment enables people to eat agricultural products that are beneficial to health and have no pollution. [0003] At present, the trace element fertilizers used in my country are mostly inorganic sulfates and chlorides. After these fertilizers are applied to the soil alone or mixed with other fertilizers, the nutrients will often be fixed or degraded into insoluble salts, resulting in low or even complete utilization of micro-ferti...

Problems solved by technology

[0003] At present, most of the trace element fertilizers used in my country are inorganic sulfates and chlorides. After these fertilizers are applied to the soil alone or mixed with other fertilizers, nutrients will often be fixed or degraded into insoluble salts, resulting in low or even complete utilization of micro-fertilizers. fail

Even if some trace elements such as ferrous iron are sprayed on the leaves, they will be quickly oxidized to high-valent iron, which is difficult to meet the needs of crop growth. In recent years, EDTA has been used as a chelating agent to produce chelated micro-fertilizers abroad, although the fertilizer efficiency has improved significantly. , but EDTA, which irritates the skin, mucous membranes, causes asthma, and the negative effects of skin rashes are emerging, it is a substance that may cause allergies, and EDTA is not easy to store after chelation, and the price is high
