Embodiment Construction

[0006] Crush the crop straw (which can be rice straw, wheat straw, cotton straw, soybean straw, etc.) The water content is about 50%, and 2 kg of high-temperature fermentation microorganisms are added to each ton of raw materials, and the raw materials are piled up into stacks with a width of 2 meters and a height of 1.2 meters for the static stacking and heating stage.

[0007] After two days of static stacking, the temperature rises to about 50 degrees, and the pile starts to be turned over once every two days, using a turning machine or manual turning. After turning, the temperature can reach about 70 degrees, and then stop turning and enter the static fertilization stage, and the temperature in this stage is maintained at about 65 degrees. After covering the fertilizer for 5 days, the temperature began to decline. After two days, the temperature dropped to about 55 degrees, and the fertilizer fermentation ended, and the water content was 25-35%. Next, use a semi-wet mate...

Abstract

The invention belongs to the field of fertilizers for agricultural planting and relates to a high-efficiency continuous cropping-resistant organic fertilizer and a preparation method thereof. The preparation method comprises the following steps that crop straws, livestock and poultry excrement, tobacco leaf waste and mushroom sticks as main raw materials are added with thermophilic microorganisms; the mixture is subjected to high-temperature fermentation; and fermentation products are added with high-efficiency continuous cropping-resistant microorganisms to form the high-efficiency continuous cropping-resistant organic fertilizer. The high-efficiency continuous cropping-resistant organic fertilizer can solves the problem of garlic and cucumber symptoms of root rotting, leaf yellowing and seedling death caused by the continuous cropping obstacle, and overcomes the defect that the same type of the existing product on the market sterilizes unthoroughly and causes soil hardening. The content of the invention relates to a high-temperature fermentation decomposition technology in raw material production, types and a use amount ratio of microorganisms for high temperature fermentation, and types and a use amount ratio of high-efficiency continuous cropping-resistant microorganisms added into a later-stage fertilizer.

Description

technical field [0001] The invention belongs to the field of fertilizers for agricultural planting, and relates to the microbial fermentation process of bio-organic fertilizers and the principle of anti-heavy cropping. Background technique [0002] In the process of modern high-efficiency facility agriculture, crops with high economic value are planted repeatedly for many years. This agricultural model has caused serious obstacles to repeated cropping in many vegetable production areas, such as rotten roots and yellow leaves of garlic, withered and dead seedlings of melons, etc. Double cropping obstacle is a soil-borne disease, which usually starts from the root system. The root cause is the monotonous cultivation of one crop for many years, which leads to the imbalance of soil nutrition and the accumulation of pathogenic bacteria of this crop. At present, the main method of anti-stubble on the market is soil chemical disinfection to kill soil microorganisms. This method lea...
