Problems solved by technology

In order to increase production in agricultural production, a large amount of chemical fertilizers are used, not only the utilization rate of chemical fertilizers is low, but also the acidification and compaction of the soil, the imbalance of nutrient ratio, and the destruction of soil structure and microbial community
Traditional organic fertilizers are rich in nitrogen, phosphorus, potassium and organic matter, which can partially replace chemical fertilizers to improve soil fertility, but the fertilizer effect is slow, and it may also bring dangers such as heavy metal poisoning

Embodiment 1

[0016] A compound biological bacterial fertilizer suitable for soil improvement of collapsing eroded land, the components of which are calculated in parts by weight: 1 part of compound fertilizer, 4 parts of Bacillus subtilis, 4 parts of Bacillus jelly-like, composted and fermented livestock 34 parts of poultry manure, 40 parts of biochar.

[0017] The mass ratio of nutrient in the compound fertilizer is N:P 2 o 5 :K 2 O=15:15:15;

[0018] The number of effective viable bacteria in the Bacillus subtilis bacterial agent is not less than 10 9 Spores / gram;

[0019] The number of effective viable bacteria in the jelly-like bacillus inoculum is not less than 10 9 Spores / gram;

[0020] The composting fermentation process of the livestock and poultry manure includes: adjusting the water content of the livestock and poultry manure to 55-65wt%, adding 0.1-0.2% of high-temperature fermentation bacteria according to the mass ratio and mixing evenly, and composting to a height of 1....

Abstract

The invention relates to compound biological bacterial fertilizer suitable for soil improvement of collapsing erosion land. The compound biological bacterial fertilizer is prepared from the followingcomponents in parts by weight: 1 part of a compound fertilizer body with the ratio of N:P2O5:K2O to be 15:15:15, 34 parts of livestock excrements subjected to composting fermentation, 40 parts of charcoal, 4-12 parts of bacillus subtilis inoculant and 4-12 parts of bacillus mucilaginosus inoculant. The compound biological bacterial fertilizer has the advantages that the nutrient elements of soil are increased, and the water retention capacity of the soil is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound biological bacterial fertilizer suitable for soil improvement of collapsing hills and eroded land. Background technique [0002] Benggang erosion land is one of the most widely distributed and most vigorously developed soil erosion types in the red soil area of ​​southern my country; the soil structure in the Benggang erosion land area is loose and low in fertility, which is not conducive to plant growth. In order to increase production, a large amount of chemical fertilizers are used in agricultural production. Not only the utilization rate of chemical fertilizers is low, but also the acidification and compaction of soil, the imbalance of nutrient ratio, and the destruction of soil structure and microbial community. Traditional organic fertilizers are rich in nitrogen, phosphorus, potassium and organic matter, which can partially replace chemical fertilizers to im...
