Complex microorganism rhzomorph modifier for saline-alkali soil and prepration method thereof

Abstract

A complex microorganism rhzomorph modifier for saline-alkali soil is characterized by comprising, by weight, 25%-35% of farmland soil, 5%-10% of active functional bacteria, 5%-15% of mineral powder, 25%-30% of organic fertilizer, 15%-20% of inorganic fertilizer and the balance of water. All the components constitute 100% in percentage. The active functional bacteria comprises bacillus megatherium, Paenibacillus kribbensis, Bacillus laterosporus, rhizobium astragali and paecilomyces lilacinus. The mineral powder is the mixture comprising one or more of peat, vermiculite, montmorillonite, zeolite, calcium carbonate, expanded perlite. The fineness of the mineral powder is equal or lower than 200 meshes. The organic fertilizer comprises thoroughly decomposed manure fertilizer, rapeseed cake fertilizer and straw fertilizer. The weight ratio among manure fertilizer, rapeseed cake fertilizer and straw fertilizer 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 compound microbial bacteriocin saline-alkali soil improver and a preparation method thereof. Background technique [0002] The compound microbial element saline-alkali soil improver 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 compound microbial element saline-alkali soil improver enter the soil and form a 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, which is beneficial Bacteria produce a large number of metabolites during the growth and repr...

AI Technical Summary

Problems solved by technology

Since the compound microbial element 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 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
