Problems solved by technology

[0003] However, the existing organic fertilizers have low nutrient content, are not easy to decompose, and the absorption process is slow, which cannot meet the requirements of high crop yield in time
The accumulation and use of traditional organic fertilizers are also very inconvenient, and the production process is complicated
Publication No. CN101468923A patent titled "Organic Fertilizer and Its Preparation Method" needs to be processed under heating and pressure during the preparation of organic fertilizers, and then lowered to normal pressure, and the liquid-solid mixture obtained is subjected to liquid-solid separation to produce The process is more complicated

specific Embodiment 1

[0017] Specific embodiment one: put 6.5 tons of cow dung into the fermentation tank, the stacking height is 1 meter, and the width is 5 meters; 1 ton of discarded mushroom sticks or peanut shells are dried and crushed, put into the fermentation tank and mixed with cow dung Evenly, when the moisture in the cow dung drops to 50% and the temperature rises to 40°C, mix the RW rot-promoting bacteria and crushed mushrooms evenly and put them in the fermentation tank; The temperature reached 65°C in the second day, and it was turned over and thrown once a day thereafter, and the temperature was controlled at 70°C. After 15 days, it was lowered to normal temperature, and the fermentation was completed, and the finished product of organic fertilizer was obtained.

specific Embodiment 2

[0018] Specific embodiment two: put 4 tons of cow dung into the fermentation tank, the stacking height is 1 meter, and the width is 4 meters; 0.5 tons of discarded mushroom sticks or peanut shells are dried and crushed, put into the fermentation tank and mixed with cow dung Evenly, when the moisture in the cow dung drops to 60% and the temperature rises to 40°C, mix the RW rot-promoting bacteria and crushed mushrooms evenly and put them in the fermentation tank; The temperature reached 55°C in the second day, and then turned over and thrown once a day, and the temperature was controlled at 60°C. After 12 days, the temperature was lowered to normal temperature, and the fermentation was completed, and the finished organic fertilizer was obtained.

specific Embodiment 3

[0019] Specific embodiment three: put 1.5 tons of cow dung into the fermentation tank, the stacking height is 0.5 meters, and the width is 2.2 meters; 0.2 tons of discarded mushroom sticks or peanut shells are dried and crushed, put into the fermentation tank and mixed with cow dung Evenly, when the moisture in the cow dung drops to 55% and the temperature rises to 40°C, mix the RW rot-promoting bacteria and crushed mushrooms evenly and apply them to the fermentation tank; The temperature reached 60°C in the second day, and then turned over and thrown once a day, and the temperature was controlled at 80°C. By the 13th day, the temperature was lowered to normal temperature, and the fermentation was completed, and the finished organic fertilizer was obtained.

Abstract

The invention relates to an organic fertilizer and a preparation method thereof. The organic fertilizer consists of dairy manure and crop waste. The organic fertilizer is prepared by the following method comprising the steps of: mixing the dairy manure and the crop waste uniformly in a fermentation tank; and when the moisture in the dairy manure is reduced to 50 to 60 percent and the temperature is raised to 40 DEG C, mixing RW rot promoting agent and crushed mushroom uniformly, applying the mixture to the fermentation tank, turning over the mixture by using a turnover machine, controlling the temperature within 80 DEG C, and completing fermentation in 12 to 15 days. The dairy manure and the waste mushroom bars or peanut shells are used as raw materials and selected from wastes in the agricultural production process, so that the agricultural wastes are secondarily utilized, the problems that the agricultural wastes are difficultly treated and environmental pollution is produced when the wastes are randomly stacked are solved, and the agricultural wastes can be transformed into the organic fertilizer with high effect by a biochemical process. The prepared organic fertilizer has rich organic nutrient content and relatively high nitrogen, phosphorus and potassium content, and is quick in the crop absorption and utilization process and low in application. In addition, compared with other similar processes for preparing the organic fertilizer, the method has the advantages that the method is simpler and easy in operation, does not occupy much manpower resource and saves the cost.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof. Background technique [0002] In today's society, people's awareness of environmental protection is getting stronger and stronger. Fertilizers used in agriculture mainly include chemical fertilizers and organic fertilizers. After chemical fertilizers are applied to farmland, although they provide nutrients for crops, they also cause irreversible pollution to soil and even groundwater, which aggravates the deterioration of the environment. Organic fertilizers not only contain a large amount of nutrients needed by plants, but also have a relatively gentle and long-lasting supply of nutrients to plants, and have a long aftereffect. After application, they can improve soil structure, promote the formation of soil aggregate structure, improve soil water retention, fertilizer retention and Air permeability, maintain the balance of microorganisms in the soil, and improve the ab...
