Problems solved by technology

There are many ways to ferment solid organic fertilizers. Solid residues from the biogas industry and industry and agriculture can be used to produce solid organic fertilizers. However, due to various influences, the fermentation cycle for making finished organic fertilizers is relatively long. If composting is used, it will take 30-40 days. days, and the fertilizer maturity is low, seriously affecting the quality of organic fertilizer and relatively narrowing the scope of application

Abstract

The invention discloses a solid organic fertilizer decomposing speed increasing method. The solid organic fertilizer decomposing speed increasing method comprises fermenting solid organic materials bycombining aerobic fermentation and anaerobic fermentation and adding in 3 different mixed microbial agents during fermentation to control moisture, temperature and time of fermentation and further toachieve the effect of increasing the decomposing speed. The solid organic fertilizer decomposing speed increasing method can complete decomposition within 24 h; obtained solid organic fertilizer hasa pH of 7.2-7.5, an organic content of 55-58%, a total nitrogen content of 2.4-2.7% and a moisture content of 26-30% and is rich in nutritional components of carbon, phosphorous, nitrogen and other microelements, low in cost and capable of significantly increasing the production speed.

Description

technical field [0001] The invention relates to the technical field of solid organic fertilizer fermentation, in particular to a method capable of increasing the rate of decomposition of solid organic fertilizer. Background technique [0002] During the growth of crops, the main nutrients needed are nitrogen, phosphorus, potassium and other elements, and the soil will lose nutrients during the long-term planting process. Therefore, fertilizing the land is to supplement the nitrogen, phosphorus, and potassium elements to the land, thereby increasing crops. output. In the process of planting, chemical fertilizers play a very important role, but with the frequent and single use of chemical fertilizers, it also brings adverse effects on the soil environment. In the absence of sufficient organic matter in the soil, the granular structure of the soil is difficult to form, and the adhesion between the soils is difficult to form, and then the water retention capacity of the soil gr...
