Slow-release fertilizer for preventing soil salinization and preparation method thereof

Abstract

The invention relates to a slow-release fertilizer for preventing soil salinization, which is prepared from 25%-35% by weight of vegetable garden soil, 5%-10% by weight of active solid bacterial strains, 5%-15% by weight of mineral powder material, 25%-30% by weight of organic fertilizer and water, and the sum of the components is 100%, wherein the active solid bacterial strains includes lactic acid bacteria, bacillus subtilis, bacillus megaterium, trichoderma, aspergillus niger, monascus, trichoderma harzianum, aspergillus aculeatus and yeast, the mineral powder material is one or a mixture of more than one of peat, zeolite, vermiculite, montmorillonite, calcium carbonate and expanded perlite, the fineness of the mineral powder material is not more than 200 mesh, the organic fertilizer contains decomposed manure, rapeseed cake fertilizer and straw, and the weight ratio of the manure to the rapeseed cake fertilizer to the straw is 5.5-7.5:2.5-3.5:0.5-1.5.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a slow-release fertilizer for preventing soil salinization and a preparation method thereof. Background technique [0002] The slow-release fertilizer that prevents soil salinization has comprehensive nutrients, can improve the soil, and improve the soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities. The beneficial microorganisms in the slow-release fertilizer to prevent soil salinization enter the soil and form a mutual symbiotic multiplication relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic role in the group , Beneficial bacteria produce a large number of metabolites during the growth and reproduction pr...

AI Technical Summary

Problems solved by technology

Since the slow-release fertilizer to prevent soil salinization contains live bacteria, drying during the granulation process has a great impact on the number of live bacteria, and because peat and humic acid are mineral organic raw materials, it is more difficult to dissolve after granulation , grains affect the quality and effect of the product

However, arable land in many places in the north belongs to machine sowing, and powder products cannot be used, so they are not granulated, which directly affects the mass use and promotion of products
