Abstract

The invention relates to the technical field of agriculture, in particular to a high-efficiency organic compound fertilizer preparation method. The method comprises the following steps of sterilization and disinfection, aerobic fermentation, vacuum dehydration and granulation coating. Accordingly, a new organic fertilizer composting technology is adopted, an intermittent cycle aerobic fermentation method is adopted, and the composting time is shortened by 3-5 days compared with an original composting technology. In addition, the invention discloses a new fertilizer coating agent. The coating agent is low in manufacturing cost, easy to manufacture, free of toxic gas in the production process, green and environmentally friendly, and a very good popularization prospect is achieved.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of agricultural technology, in particular to a preparation method of high-efficiency organic compound fertilizer. [0003] 【Background technique】 [0004] With the development of agricultural production, the amount of fertilizer application will increase day by day. At present, my country has become the world's largest producer, user and importer of fertilizers. The annual consumption of chemical fertilizers in my country has exceeded 30 million tons. , Lack of carbon sources, with the continuous use of inorganic fertilizers, the carbon and nitrogen balance of the soil is destroyed, resulting in serious problems such as compaction and desertification of the soil, decline in fertility, and crop yield reduction. [0005] Organic fertilizers are rich in organic matter, which can improve soil problems caused by long-term use of inorganic fertilizers. However, organic fertilizers must be retting and decomposed, and...
