Microbial foliar fertilizer for improving plant adverse resistance and preparation method thereof

Abstract

The invention discloses a microbial foliar fertilizer for improving the plant adverse resistance. The microbial foliar fertilizer is prepared from 50-70 parts of molasses, 3-5 parts of bacillus subtilis, 10-20 parts of amino acid, 1-5 parts of citric acid, 5-8 parts of Na-EDTA, 2.1-3 parts of sodium tetraborate, 3.2-4 parts of zinc sulfate monohydrate;, 3.2-4 parts of manganese sulfate monohydrate, 0.5-1 part of ammonium molybdate and 40-50 parts of water. The invention further discloses a preparation method for the microbial foliar fertilizer for improving the plant adverse resistance. The preparation method comprises the following steps that (1) the molasses and the bacillus subtilis are coupled so as to obtain a base material I; (2) the water is added into a second reaction kettle, heating is carried out to reach 30-40 DEG c, then the amino acid and the citric acid are added so as to obtain a mixed solution; and (3) then the Na-EDTA, the sodium tetraborate, the zinc sulfate monohydrate, the manganese sulfate monohydrate and the ammonium molybdate are sequentially added into the second reaction kettle and are subjected to mixed reaction, after the reaction is completed, the basematerial I is added, and filtering is carried out so as to obtain the microbial foliar fertilizer.

Description

technical field [0001] The invention belongs to the field of agricultural science and technology, and relates to agricultural fertilizers, in particular to a microbial foliar fertilizer for improving stress resistance of plants and a preparation method thereof. Background technique [0002] Foliar fertilizer refers to the fertilizer that directly applies the nutrients needed by crops to the leaves of plants for the purpose of plant absorption. Foliar fertilization can make nutrients directly enter the plant body from the leaves, participate in the metabolism of plants and the synthesis of organic matter, and is more effective than soil fertilization, so it is deeply loved by farmers. [0003] The foliar fertilizers currently on the market generally focus on providing nutrients to plants with chemical additives. The nutrients provided are directly used on the aboveground parts of plants, and the effect on plant roots is only indirect and small. [0004] Most of the foliar fe...

Problems solved by technology

[0005] At present, only a small number of foliar fertilizers add stress-resistant ingredients, such as abscisic acid, proline, etc., but these biologically active substances are generally seldom used in foliar fertilizers due to their high prices. In the face fertilizer, because of its high cost, the production cost of farmers will be increased correspondingly, which is not conducive to popularization and application
