Preparation process for producing organic fertilizer from plant straws and traditional Chinese medicine residues

Abstract

The invention discloses a preparation process for producing an organic fertilizer from plant straws and traditional Chinese medicine residues. The method comprises the following steps: directly mixingthe plant straws with the traditional Chinese medicine residues without crushing, regulating the humidity and carbon-nitrogen ratio, inoculating an organic material decomposition agent, carrying outwindrow fermentation in a sunshine tile fermentation workshop for 14-20 days, completely killing pathogenic bacteria, worm eggs, grass seeds and the like at high temperature, then transferring the mixture into a biological fermentation greenhouse to carry out secondary bin type fermentation, and controlling the temperature and humidity in the greenhouse to quickly decompose and degrade hemicellulose, cellulose, lignin and the like in the plant straws and the traditional Chinese medicine residues; removing a large amount of water in the plant straws and the traditional Chinese medicine residuesin the processes of composting and turning for 3-5 times by heat-producing microorganisms by applying the principle of biological drying, deodorizing and killing poisonous and harmful substances, transferring the mixture to a fermentation workshop to be fermented for 5-7 days in the after-ripening period 25-30 days later, and finally producing brown powdery high-quality organic fertilizer whose quality meets the standardNY525-2012 . The process is simple, the fertilizer is safe, the application range is wide, and the fertilizer can be safely applied to any plant.

Description

technical field [0001] The invention belongs to the production field of organic fertilizers, and in particular relates to a preparation process of organic fertilizers produced from plant straws and traditional Chinese medicine dregs. Background technique [0002] my country is a large grain-producing country, with an annual output of more than 800 million tons of crop straw. For a long time, straw has been generally incinerated in rural areas. According to rough statistics, straw incineration in the country accounts for about 30% of the total reserves, and the exhaust gas brought by the burning of straw has brought serious air pollution; especially, in recent years, my country has frequently experienced large-scale deep smog, and it is necessary to solve this problem The problem is already an urgent one. [0003] On the other hand, in order to increase soil organic matter, the state has adjusted the structure of chemical fertilizer application, improved fertilization methods...

Problems solved by technology

Since chickens, pigeons, and pigs are now farmed on a large scale in factories, many antibiotics are added to their feed, so the feces produced by them contain a lot of heavy metals and antibiotics. It is impossible to remove heavy metals and antibiotics in the medium, so the fertilizer produced can only be applied on landscaping, flowers and lawns. If it is applied on other field crops and economic crops, it may cause harm to the human body

The main raw materials of plant-derived organic fertilizers are various crop straws, but the process of making organic fertilizers is complicated. If the crop straws are not crushed to a certain extent, they cannot be fermented, and the compatibility of different types of straws is not in place, resulting in the quality of the produced organic fertilizers. Less than the requirements of the organic fertilizer industry standard NY525-2012

Moreover, organic fertilizers will have odor and toxic and harmful substances, which need further improvement
