Problems solved by technology

Since the microbial organic fertilizer for improving saline-alkali land contains live bacteria, the drying during the granulation process has a great impact on the number of live bacteria, and because peat and humic acid are mineral organic materials, it is more difficult to dissolve after granulation, and the impact of granulation Product quality and effectiveness
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

Abstract

A microbial organic fertilizer for improving a saline and alkaline land is characterized by being prepared from phosphorylated hydroxyethyl cellulose, grafted polyvinyl alcohol butene diacid monoesterammonium salt, a granular saline and alkaline land water-retention slow release fertilizer semi-finished product, high water-absorption resin and a solid culture, wherein the weight of the phosphorylated hydroxyethyl cellulose is 5-10% of the total weight of the water-retention and fertilizer-retention slow release fertilizer, the weight of the grafted polyvinyl alcohol butene diacid monoester ammonium salt is 5-10% of the total weight of the water-retention and fertilizer-retention slow release fertilizer; the weight of a base fertilizer is 80-90% of the total weight of the water-retention and fertilizer-retention slow release fertilizer; and the weight of the solid culture is 1-5% of the total weight of the water-retention and fertilizer-retention slow release fertilizer.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a microbial organic fertilizer for improving saline-alkali land and a preparation method thereof. Background technique [0002] The microbial organic fertilizer for improving saline-alkali land has comprehensive nutrients, which 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 microbial organic fertilizer for improving saline-alkali land 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 effect on the group. In the process of growth and reproduction, a large number of metaboli...
