Abstract

The invention relates to a compound microbial fermented soil conditioner including the following raw materials in parts by weight: 290-315 parts of urea, 290-315 parts of a nitrogen and potassium compound fertilizer, 235-260 parts of ammonium dihydrogen phosphate, 40-60 parts of potassium pyrophosphate, 1-3 parts of chelated iron, 3-5 parts of chelated zinc, 80-100 parts of a fermented product oflignite or weathered coal and a microbial agent, and 900-1100 parts of an anticaking agent. The compound microbial fermented soil conditioner provided by the invention comprises humic acid rich in mineral sources, solves the problems of soil hardening, acidification, salinization and the like, also has a good role in promoting plant root systems, and greatly improves other corresponding agronomictraits. The microbial agent has the abilities of nitrogen fixation, phosphorus removal, potassium removal, plant hormone production or antibiotic secretion, promotes the material circulation and nutrient supply in soil, and improves the soil fertility and the fertilizer utilization rate.

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a compound microbial fermentation soil conditioner and a preparation method thereof. Background technique [0002] Humic acid (Humic Acids) is a class of macromolecular substances that widely exist in the natural environment. It has a complex structure and a variety of active functional groups. It can interact with many organic and inorganic substances. One of the important factors of behavior and fate. Natural humic acid widely exists in soil, river mud, marine sediment, lignite and weathered coal, and its types can be divided into three categories: soil humic acid, water humic acid and coal humic acid. Among them, the total amount of humic acid in soil is the largest, but the average content is less than 1%; the total amount of humic acid in water body is also a lot, but the concentration is lower, so it is almost impossible to develop it as a resource. The mos...
