Microbial fertilizer capable of improving soil structure

Abstract

The invention discloses a microbial fertilizer capable of improving soil structure, which is characterized by comprising the following components in parts by weight: 50-90 parts of livestock and poultry manure, 4-9 parts of sodium dihydrogen phosphate, 5-6 parts of disodium hydrogen phosphate, 6-15 parts of sodium polyphosphate, 4-9 parts of earthworm manure, 8-13 parts of rape cake, 40-55 parts of chicken manure, 15-35 parts of rice bran, 10-15 parts of wheat bran, 14-24 parts of bean straw, 5-9 parts of potato straw, 0.1-0.3 part of lactobacillus powder, 0.1-0.4 part of nitrobacteria powder and 0.1-0.2 part of rhizobia powder. The microbial fertilizer contains rich beneficial microbes, has the advantages of comprehensive and balanced nutrients and persistent effect, and can enhance the organic matter content in soil.

Description

technical field [0001] The invention relates to a microbial fertilizer for improving soil structure. Background technique [0002] Fertilizer is the food of plants, and fertilization is an essential means to ensure high and stable crop yields in the agricultural production process. The fertilizers currently used mainly include single inorganic fertilizers, compound fertilizers and organic-inorganic compound fertilizers. According to statistics, the contribution rate of inorganic fertilizers to grain is about 35%. Although inorganic fertilizers have a relatively obvious effect on increasing grain production, in recent years, with the increase in the application of inorganic fertilizers, there have been adverse phenomena such as damage and decline in organic matter content. . Organic fertilizers are usually obtained by heaping waste rich in organic matter, but there are disadvantages of time-consuming, labor-intensive, pollution and nutrient loss, and it also causes the spre...

According to statistics, the contribution rate of inorganic fertilizers to grain is about 35%. Although inorganic fertilizers have a relatively obvious effect on increasing grain production, in recent years, with the increase in the application of inorganic fertilizers, there have been adverse phenomena such as damage and decline in organic matter content.

Organic fertilizers are usually obtained by heaping wastes rich in organic matter, but they have the disadvantages of time-consuming, labor-intensive, pollution and nutrient loss, and also cause the spread of pathogenic bacteria, causing certain damage to crops, soil and the environment.
