Problems solved by technology

Many studies on the resource utilization of agricultural waste have shown that agricultural waste has great potential in fertilizer, feed, energy and carbon emission reduction. However, the phenomenon of random dumping and direct combustion of agricultural waste is very common, and processing The method is relatively extensive, not only failing to realize the potential resource value of agricultural waste, but also causing serious agricultural "three-dimensional environmental pollution", including agricultural surface water pollution, agricultural non-point source pollution and rural air pollution.

Embodiment 1

[0028] Preparation of organic fertilizer: Mix the pulverized raw materials in parts by weight of 300 parts of cow dung, 200 parts of sheep manure, 100 parts of chicken manure, 350 parts of corn stalks, and 50 parts of crab shell powder, and stack the mixed materials in a 60.0 m, a width of 5.0m, and a height of 1.8m in a trough-type fermentation tank, the height of stockpiling in the trough is 1.5m, and water is added to adjust the water content to 53%. After 48 hours of stacking, the temperature in the stack was detected to be 62°C. Turn the pile once a day. After 8 days, the material is completely fermented and decomposed. The temperature of the pile will drop to 31°C, and the moisture content will be 30%. The material is taken out and pulverized for the second time, and passed through a 12-mesh sieve to obtain a powder organic fertilizer.

Abstract

The invention provides a method for preparing a biological fertilizer capable of effectively overcoming continuous cropping obstacles by using agricultural organic wastes and a composite microbial inoculant, belonging to the fields of agricultural organic waste harmless treatment and utilization technique and biological control. The biological organic fertilizer is prepared by mixing the following components in parts by weight: 600-800 parts of livestock / poultry manure, 200-400 parts of crop straw, 10-50 parts of crab shell powder and 5-10 parts of composite microbial inoculant. By fully utilizing the livestock / poultry manure and crop straws in crop farming, the biological organic fertilizer reduces the environmental pollution, recycles two types of agricultural organic wastes, and changes wastes into valuable substances. The biological organic fertilizer has favorable control effects on root knot nematode disease, epidemic disease, blight and the like of vegetables, and is capable of improving the soil, enhancing the soil fertility and increasing the crop yield.

Description

technical field [0001] The invention discloses a method for preparing bio-organic fertilizer capable of effectively overcoming continuous cropping obstacles by utilizing agricultural organic waste and a compound microbial agent, and belongs to the fields of harmless treatment of agricultural organic waste and its utilization technology and biological control. Background technique [0002] Due to the structural adjustment of my country's modern agricultural industry, the improvement of intensification, and the increase in people's demand for specific crop products, the phenomenon of large-scale continuous planting of a single crop or the same family of crops is becoming more and more common. After crop continuous cropping, it will lead to aggravation of pests and diseases, poor plant growth, yield and quality decline, that is, continuous cropping obstacles. At present, continuous cropping obstacles have become an important factor that seriously restricts the development of my...
