Saline alkali soil improvement agent, and preparation method thereof

Abstract

The invention discloses a bio-organic fertilizer specially used in saline-alkali soil. The bio-organic fertilizer comprises, by weight, 100 parts of crop straw powder, 3 to 5 parts of humic acid, 20 to 22 parts of chitosan, 1 to 10 parts of diatomite, 4.6 to 4.8 parts of a ferment bacterial fertilizer, 5 to 6 parts of shell powder, 5 to 6 parts of a solid inoculum, 0.5 to 1 part of borax, 2 to 4 parts of zinc sulfate, 3 to 3.2 parts of rice husk carbon micro powder, 2.5 to 2.6 parts of gypsum powder, 2 to 3 parts of sodium dodecyl benzene sulfonate, 34 to 36 parts of pine needle rotted leaf soil, 1 to 1.2 parts of para molybdic acid, 0.9 to 1.1 parts of pyruvic acid, 1 to 1.2 parts of ulmic acid, 6 to 7 parts of nitro humic acid, 1.2 to 1.4 parts of a metal complex ion, and an appropriate amount of water.

Description

Technical field [0001] The invention relates to the field of fertilizers, in particular to a saline soil conditioner and a preparation method thereof. Background technique [0002] The saline soil amendment has comprehensive nutrients, which can improve the soil and improve soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, and enhance the ability of soil to retain water, fertilizer, and supply. The beneficial microorganisms in the saline soil conditioner enter the soil and form a symbiotic multiplication relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform into beneficial bacteria, interact and promote each other, and play a synergistic effect in the colony. A large number of metabolites are produced during the growth and reproduction process, which promotes the decomposition and transformation of organic matter, can directly or indirectly provide a variety of nutrients and ...

AI Technical Summary

Problems solved by technology

Since the saline-alkali soil improver 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 granulation will affect the product. quality and effect

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
