Abstract

The intention discloses a biological organic fertilizer with a saline-alkali soil improvement effect and a preparation process thereof, and belongs to the technical field of biological fertilizers. According to the present invention, the comprehensive utilization of modern antibacterial active substances and the mixed microbial fermentation technology are integrated, livestock manure, straw, Chinese herb raw materials and seaweed oligosaccharide are fermented through the synergistic effect of microorganisms, the synergistic effect among the raw materials is completely provided, and the efficient and green fermentation biological organic fertilizer is developed. The product has remarkable saline-alkali soil improvement and saline-alkali soil grain yield increase effects, and can promote release of organic matters in soil, improve the physicochemical structure of salinized soil, increase soil aggregate and permeability, improve soil fertility and improve the grain yield increase capacityof saline-alkali soil.

Description

technical field [0001] The invention relates to a bio-organic fertilizer with the effect of improving saline-alkali land and its preparation process, in particular to a bio-organic fertilizer which can significantly improve saline-alkali land and increase grain production by using a variety of probiotics to synergistically ferment livestock and poultry manure, straw, Chinese herbal medicine and other raw materials. The technology of organic fertilizer belongs to the technical field of biological fertilizer. Background technique [0002] Soil salinization is considered a major threat to environmental resources and human health in many countries, with nearly 1 billion hectares (hm 2 ), accounting for about 7% of the Earth's continental area. According to statistics, the total area of ​​saline-alkali land in my country has reached 99.1 million hectares (hm 2 ), ranking third in the world, only containing less saline-alkali soil than Russia and Australia, accounting for about ...
