Stalk microbe soil conditioner and its prepn

Abstract

The present invention relates to one kind of stalk microbe soil conditioner and its preparation process. The stalk microbe soil conditioner is prepared through crushing stalk into powder; steam blasting, adding water, high temperature steam sterilizing and microwave treating; cooling, spraying bacteria seed and mixing with culture liquid; anaerobic and aerobic solid fermentation to obtain cultured matter, and classified culturing fermentation to prepare the stalk microbe soil conditioner. The stalk microbe soil conditioner is used in improving soil, promoting root system growth, decomposing potash and phosphate, raising fertilizer effect, inhibiting harmful bacteria in soil, preventing diseases of crop, increasing crop yield and improving agricultural product quality.

Description

technical field [0001] The invention relates to a straw microbial soil improver and a preparation method thereof. Background technique [0002] The soil is compacted, pesticide residues are serious, soil-borne diseases are rampant, soil water retention capacity is reduced, air permeability is poor, and decomposition and reduction capabilities are reduced; farmers' awareness of environmental protection is weak, and they are highly dependent on petrochemicals. Few people use hoes to weed and loosen field crops Soil, ventilation, and business protection, but just spraying the herbicide, which causes the soil to be extremely deteriorated; the water quality is seriously polluted, which leads to an increase in the incidence of disease. Now the groundwater above 10 meters in the vast rural areas has become astringent and bitter, and the water quality contains a lot of pesticides and pesticide residues. In some rural areas, if you want to drink clean water, you must hit 20 meters b...

Problems solved by technology

Moreover, groundwater depletion has already occurred in many areas, and this phenomenon is becoming more and more serious; in order to pursue production, farmers are applying more and more chemical fertilizers to the land and spraying pesticides on crops, resulting in serious soil pollution. The pesticide residues in the produced agricultural products exceed the standard by several times or even dozens of times

[0003] Moreover, there is no more effective way to use crop straw. Although returning straw to the field can avoid the harm of burning, it takes a long time to decompose, which brings inconvenience to farming; at the same time, it brings problems such as diseases and insect pests.

Cannot fundamentally solve the problem of straw utilization
