Preparation method of multifunctional liquid fertilizer capable of improving crop immunity

Abstract

The invention provides a preparation method of a multifunctional liquid fertilizer capable of improving crop immunity, and relates to the technical field of medical fertilizers. According to the preparation method of the multifunctional liquid fertilizer capable of improving the crop immunity, the multifunctional liquid fertilizer is prepared from the following components in parts by mass: 30-50 parts of fish residues, 20-25 parts of oil cakes, 10-15 parts of urea, 10-15 parts of monopotassium phosphate, 5-8 parts of ethylenediamine tetraacetic acid, 3-5 parts of papain, 3-5 parts of sodium molybdate, 2-4 parts of boric acid, 0.9-1.3 parts of indoleacetic acid, 3-5 parts of pepsase, 3-5 parts of hydrochloric acid and 1.5-2.5 parts of calcium carbonate. By using the fish residues and the oil cakes, the cost of the liquid fertilizer is very low, proteins in the fish residues and the oil cakes are hydrolyzed into polypeptides through pepsase and papain, the polypeptides are easily absorbed by crops to enhance the immunity of the crops, and fishbone in the fish residues can be dissolved and softened through hydrochloric acid. Calcium ions, iron ions and magnesium ions can be chelated through ethylenediamine tetraacetic acid, plants can absorb the liquid fertilizer more easily, the effect of the liquid fertilizer is improved, and the liquid fertilizer is worthy of being widely popularized.

Description

technical field [0001] The invention relates to the technical field of medicinal fertilizers, in particular to a preparation method for improving crop immunity and multifunctional liquid fertilizers. Background technique [0002] my country is the world's largest producer and consumer of chemical fertilizers. Although the arable land accounts for 7% of the world's total, the total population of our country accounts for 20% of the world's total. Therefore, my country must Rely on chemical fertilizers, but the large amount of chemical fertilizers used and the low utilization rate have caused serious pollution to the soil environment in our country. The unreasonable use of fertilizers has caused groundwater nitrate to exceed the standard. Therefore, the environmental protection concept of green water and green mountains is golden mountains and silver mountains. It is a great challenge. The current promotion of liquid fertilizer in the market has achieved the purpose of less ferti...
