High-quality organic fertilizer prepared by straw and livestock and poultry night soil and method thereof

Abstract

The invention provides a method for preparing a high-quality organic fertilizer by straw and livestock and poultry night soil, which belongs to the biology fertilizer field. The organic fertilizer is prepared by the following components by weight ratio,25-35% of straw, 50-60% of livestock and poultry night soil, 10-20% of plant ash, 0.5-1% of inorganic fertilizer, and 0.1-0.2% of microbial inoculum. The preparation method of the organic fertilizer comprises the following steps: preparing a microbial inoculum, drying straw, crushing, mixing with livestock and poultry night soil, plant ash, an inorganic fertilizer and the microbial inoculums according to a certain proportion, uniformly stirring, piling the mixed raw materials into a stripe, regularly measuring the temperature of piles, timely turning and stirring, and completing decomposing after 2-3 weeks to obtain the organic fertilizer. The preparation method is simple, the prepared organic fertilizer has comprehensive nutrient composition, and can reach a national standard for the organic fertilizer, processing for waste can be completed, and waste resource reutilization and environment protection can be realized.

Description

Technical field: [0001] The invention relates to the field of organic fertilizers, and relates to the production of organic fertilizers by using breeding and planting waste. Background technique: [0002] With the improvement of farmers' living standards and the improvement of agricultural mechanization, the amount of planting waste is increasing, and the utilization rate is decreasing. The main straws include straw, rice husk, wheat stalks, corn stalks, etc. Incineration or discarding, incineration will produce harmful gases, cause serious environmental pollution, aggravate the greenhouse effect, and have a negative impact on road traffic safety, and discarding will cause environmental pollution and waste of resources. With the decrease of one family of farmers, the increase of large-scale and specialized farms, and the inconvenient transportation of fresh manure, there is currently a huge amount of breeding waste, mainly livestock and poultry manure. The traditional treatm...

Problems solved by technology

Direct utilization is the most direct and trouble-free method. Straw and manure are put directly into the farmland without treatment, and are slowly decomposed by microorganisms in the soil, releasing the mineral nutrients in them for absorption and utilization by crops. Organic matter and humus provide food for microorganisms and other organisms in the soil, which can improve soil structure, soil fertility, and crop yields to a certain extent, but the natural decomposition rate is slow, especially straw wastes are slow to decompose. damage crop roots
