Fermentation method of organic fertilizer

Abstract

The invention relates to a fermentation method of organic fertilizer. The fermentation method comprises the following steps: weighing straw powder, grass ash, farm manure, rice husk powder, a biological bacterium agent and calcium superphosphate in parts by weight; paving the grass ash in a fermentation tank; then flatly paving the straw powder on a first layer in the fermentation tank, flatly paving the farm manure on a second layer, flatly paving the rice husk powder on a third layer and flatly paving the farm manure on a fourth layer; adding warm water into the fermentation tank; carrying out first-time fermentation; stirring fertilizer and flatly paving one layer of the grass ash on the fertilizer; carrying out second-time fermentation; opening a sealing cover and stirring the fertilizer; then applying the calcium superphosphate and the biological bacterium agent to the fermentation tank; overturning the fertilizer in the fermentation tank for a plurality of times from top to bottom; then closing the fermentation tank and carrying out third-time fermentation; conveying the fertilizer subjected to the third-time fermentation into an extruding separation device; adding prepared mixed powder into granulation equipment. According to the fermentation method of the organic fertilizer, the quality of soil can be improved, the fertility of the soil is increasedimproved, and a condition that the fertilizer is used for a long period so that the fertility of the soil is damaged can be prevented.

Description

technical field

[0001] The invention relates to the field of fertilizers, in particular to a method for fermenting organic fertilizers. Background technique

[0002] In recent years, the input of chemical fertilizers has increased significantly. Due to the single type of nutrients contained in chemical fertilizers, long-term application will easily cause nutrient imbalance in soil and food, cause nutrient loss, pollute the environment, and improper application will reduce the quality of agricultural products. Long-term large-scale application of chemical fertilizers will inhibit the activities of soil microorganisms, resulting in a decline in the self-regulating ability of the soil. Therefore, although the single nutrient contained in chemical fertilizers is high and the amount of application is small, it is not possible to apply chemical fertilizers for a long time in today's increasingly demanding living environment. Therefore, the development of organic fertilizers is of ...
