Method for preparing microbial liquid fertilizer fermented animal dung transformed organic fertilizer

Abstract

The invention discloses a method for preparing microbial liquid fertilizer fermented animal dung transformed organic fertilizer. The method comprises the steps of adding actinomycetes and rhizobia into EM original dew, mixing uniformly, and standing to obtain a microbial liquid fertilizer; mixing crop straw powder or weed powder, animal dung powder and water uniformly, adding the microbial liquid fertilizer, and performing primary anaerobic fermentation to obtain a primary fermented material; adding saccharomycetes and photosynthetic bacteria, and performing secondary anaerobic fermentation to obtain an animal dung fermented organic fertilizer; and drying and granulating to obtain the microbial liquid organic fertilizer fermented animal dung transformed organic granular fertilizer. The preparation method is simple; the crop straw powder, the weed powder and the animal dung powder serving as raw materials are subjected to probiotics-orientated fermentation under the coaction of other beneficial microbes through two steps of fermentation, so that soil nutrients can be effectively utilized, phosphorus and potassium can be decomposed, nitrogen can be fixed, the consumption of the fertilizer can be reduced, the fertilizer has a good use effect, nutrients which are unlikely to decompose in plants are effectively utilized, soil hardening is effectively eliminated, and the purpose of increasing the yield is achieved.

Description

technical field

[0001] The invention relates to a method for transforming organic fertilizer by fermenting animal dung with microbial liquid fertilizer. Background technique

[0002] In order to increase the yield of crops, the amount of chemical fertilizers has increased sharply when planting farmland. The average amount of chemical fertilizers used in some areas of my country has reached more than 300kg / hm in terms of pure nutrient content, which is far beyond the developed countries. To prevent water pollution caused by chemical fertilizers The set safety upper limit is 225kg / hm.

[0003] With the rapid development of the large-scale livestock and poultry industry, most of the huge amount of livestock and poultry manure produced is not properly treated, piled up and placed randomly, and the N, P, K and harmful pollutants contained in the livestock and poultry manure Bacteria, etc. enter surface water and groundwater, leading to water pollution and excessive nitrate nitrog...
