High-efficiency biological liquid fertilizer taking livestock liquid dung as raw material and preparation method of fertilizer

Abstract

The invention provides a high-efficiency biological liquid fertilizer taking livestock liquid dung as a raw material and a preparation method of the fertilizer, and belongs to the technical field of agricultural production. The high-efficiency biological liquid fertilizer comprises the following components in parts by weight: 1 part of diluted liquid dung, 0.06-0.2 part of bran and 0.1-0.15 part of a composite microbial agent, wherein the diluted liquid dung is prepared by diluting the livestock liquid dung by water according to the weight ratio of 1:4 to 1:6; the composite microbial agent is prepared by mixing strains and EM stoste according to the weight ratio of 5:6 to 7:3; and the strains comprise two or three of trichoderma viride, saccharomyces cerevisiae and bacillus subtilis. The preparation method for the high-efficiency biological liquid fertilizer comprises the following steps of: adding the diluted livestock dung into the bran and the composite microbial agent, and performing anaerobic fermentation, filtration and nitrogen, phosphorus and potassium nutritious component mixing on the mixture, thus preparing the biological liquid fertilizer. The liquid fertilizer preparation method is high in fermentation speed, short in preparation period and high in fermentation degree; the high-efficiency biological liquid fertilizer can be obtained; the effect of increasing the yield of crops is obvious; the livestock liquid dung is effectively used in a recycled manner; and the pollution to the environment is reduced.

Description

technical field [0001] The invention provides a biological liquid fertilizer and a preparation method thereof, in particular to a biological liquid fertilizer using livestock and poultry manure as a raw material, which belongs to the technical field of agricultural production. Background technique [0002] With the continuous improvement of the intensification of animal husbandry in my country, the scale of animal husbandry is increasing day by day, and due to the needs of transportation, sales and processing, most of the intensive livestock and poultry farms are built in densely populated, convenient transportation and abundant water sources. However, more than 80% of the intensive livestock and poultry farms do not have corresponding supporting facilities to absorb the livestock and poultry manure produced by them, and the ensuing negative impact is that the discharge of livestock and poultry manure continues to increase. At present, there are three main methods for the tre...

AI Technical Summary

Problems solved by technology

For large-scale intensive farms, flushing cleaning methods are generally used, and the amount of livestock and poultry manure produced is much higher than that of livestock and poultry manure. Therefore, these two methods cannot quickly and effectively solve the problem of farm manure.

At the same time, the study believes that although adding exogenous microorganisms to the aquaculture water can achieve certain results, these strains may not be able to reproduce successfully in the water and become the dominant flora to regulate the water environment, and they are easy to die over time
