Problems solved by technology

Soil salinization prevents large areas of land from being effectively used, seriously affecting agricultural production and improving farmers' living standards
[0003] At present, in many saline-alkaline soil improvement measures, water conservancy engineering measures, agricultural cultivation measures, halophytes, chemical modifiers and other methods have been widely used, but the effect is not satisfactory
Although chemical improvement measures can quickly change the soil structure, it may also cause secondary pollution; agricultural measures need to consume a lot of manpower, material and financial resources; biological improvement measures are slow to take effect and have a long cycle

Abstract

The invention belongs to the technical field of fertilizer preparation and particularly relates to organic microbial compound fertilizer for improving saline-alkali soil and a preparation method of the organic microbial compound fertilizer. The organic microbial compound fertilizer is prepared from components in parts by weight as follows: 40-80 parts of municipal sludge, 20-40 parts of crop residues, 10-30 parts of duckweeds, 5-15 parts of algae, 10-30 parts of a microbial agent, 5-15 parts of citrate-soluble potassium fertilizer and 5-15 parts of phosphorus humate, and the organic microbialcompound fertilizer is prepared with processes including composting and the like. The organic microbial compound fertilizer has the economical and environment-friendly advantages, after the organic microbial compound fertilizer is applied to treatment of the saline-alkali soil, alkalinity of the saline-alkali soil can be neutralized, pH value of soil is reduced, content of organic matter in soil is greatly increased, aggregate stability, water binding capacity and water-retaining property of the soil are enhanced, soil hardening is reduced, and soil salinity is reduced year after year.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to an organic microbial compound fertilizer for improving saline-alkali land and a preparation method thereof. Background technique [0002] Saline-alkali land is the general term for all kinds of saline soil, alkaline soil and salinized and alkalized soil. According to the amount of saline-alkali content in the soil, it can generally be divided into three types: mild, moderate and severe saline-alkali land. As an important land resource, soil Salinization has seriously affected the regional ecological environment and food production. According to incomplete statistics from UNESCO and FAO, the global saline-alkali land area reaches 955 million hm 2 , while the total area of ​​saline-alkali land in my country is about 99.14 million hm 2 , ranking third in the world. Saline-alkali soil is mainly characterized by stickiness when wet and poor air permeabili...
