Microbial organic manure and preparation method thereof

Abstract

The invention relates to an agricultural organic fertilizer, and specifically relates to a microbial organic manure and preparation method thereof. The microbial organic manure comprises a microbial organic fertilizer and an absorption microbial fertilizer. Wherein, the proportion of the absorption microbial fertilizer to the microbial organic fertilizer is 5%-10% by mass. According to the invention, microbes are utilized to accelerate the decomposition of raw materials and kill harmful pathogenic bacteria in livestock and poultry dungs. When the manure of the invention is spread into soil, the bacterial strains in the manure reproduce rapidly so that the nutrient potential of the environment can be brought into full play. In addition, lots of fresh humus generated in fermentation can improve the soil, improve fertilizer conservation and supply capability as well as ventilation and water permeability of the soil, stimulate plant growth, and strengthen plant nutrient supply and diseaseresistance of crops.

Description

[0001] technical field

[0002] The invention relates to an agricultural organic fertilizer, in particular to a microbial organic fertilizer and a preparation method thereof. Background technique

[0003] At present, due to the long-term use of inorganic fertilizers in agricultural production, the utilization rate of chemical fertilizers is reduced, 65%-75% of nitrogen fertilizers are wasted, and the groundwater enters rivers, causing environmental pollution, soil compaction, water retention and fertilizer retention, and soil microorganisms. The ecological balance is destroyed, the yield of crops decreases, the enrichment of toxic elements in plants, and the quality decline, while the pesticides used cause residues and pollute the environment. If the manure of poultry and livestock is not handled properly, it will become another factor of environmental pollution. With the improvement of people's requirements for the safety and quality of agricultural products, the enhancemen...

Embodiment 3

[0046] Taking greenhouse tomato as the test material, two treatment groups were designed, the control group using common compost and the test group using microbial organic fertilizer. Both fertilizers were used as base fertilizer, and the usage rate was 3000kg / mu. Each experimental treatment group set 4 repetitions, each repetition 100m 2 , routine management. Observe the influence of microbial organic fertilizer on tomato yield, see Table 1 for details.
