Special bio-organic fertilizer for rice planted in saline-alkali soil and preparation method of special bio-organic fertilizer

Abstract

The invention discloses a special bio-organic fertilizer for rice planted saline-alkali soil. The special bio-organic fertilizer is prepared from halomonas, bacillus subtilis, paenibacillus polymyxa, bacillus thuringiensis, lactobacillus plantarum, Rubrivivax gelatinosus and an organic fertilizer. In actual preparation, microorganisms are propagated to obtain a microbial agent, then decomposed cow dung and auxiliary materials are uniformly mixed, granulation and drying are performed, cooling treatment is performed, a mixed solution of the microbial agent and a coating agent is added through a coating barrel for coating treatment, packaging is performed, and the finished product can be used after being packaged and stacked in a warehouse for a period of time. The bio-organic fertilizer has a high organic matter content and a high viable count, and can improve the soil structure of saline-alkali soil, reduce soil salinity and a pH value, enhance crop stress resistance, promote rice growth, increase yield and achieve the effects of soil improvement, fertility improvement, stress resistance and growth promotion when used in cooperation with conventional irrigation and fertilization measures.

Description

technical field [0001] The present application relates to the field of biology, in particular to a rice bio-organic fertilizer specially used for saline-alkali land and a preparation method thereof. Background technique [0002] The fundamental reason for the formation of saline-alkali soil is large evaporation and poor drainage. Therefore, in the early stage of improvement, the focus should be on improving the water status of the soil. Generally, it is carried out in several steps. First, drain and wash salt to reduce the salinity content of the soil; then plant salt-resistant plants to fertilize the soil; finally plant crops. The specific improvement measures are: drainage, irrigation and salt washing, agronomic measures to improve fertilizer. [0003] In many countries, soil salinization is considered to be a major threat to environmental resources and human health, with nearly 1 billion hectares (hm 2 ), accounting for about 7% of the Earth's continental area.
