Composting is an ancient and simple method of disposing of organic waste and making fertilizers. With the deepening of research and the improvement of methods, its application is highly valued by various countries, because it has good ecological significance and is also important for agricultural production. Come benefit. There are many reports that the preparation of seedbeds with decomposed compost can inhibit soil-borne diseases. And the antagonistic bacteria that come after the high temperature stage of the composting process can make the number of bacteria reach a high level; the organic matter in the composting process is difficult to decompose, stable, and easily absorbed by crops under the action of microorganisms; at the same time, microorganisms act on Reduce the toxic effects of heavy metals within a certain range. It can be seen that composting is a simple and effective method to make bio-organic fertilizer, which is beneficial to the development of ecological agriculture. In the process of composting, a compost windrow turner is generally used.
Most domestic organic fertilizer products are only composted and fermented for 15-20 days. Such products can only reach harmless standards. The high-quality organic fertilizer compost fermentation process generally takes 45-60 days.
This is because in the warming stage and high temperature stage of the composting stage, harmful microorganisms such as plant pathogenic bacteria, insect eggs, weed seeds, etc. will be killed. However, the main role of microorganisms in this process is metabolism and reproduction, and only a small amount is produced. Metabolites, and these metabolites are unstable and not easily absorbed by plants. In the later cooling period, the microorganisms will humify organic matter and produce a large amount of metabolites that are beneficial to plant growth and absorption. This process takes 45-60 days.
After this process, composting can achieve three goals, one is harmlessness; the other is humusification; and the third is a large number of microbial metabolites such as various antibiotics and protein substances. Only the materials that are decomposed by fermentation can be granulated with organic fertilizer by the organic fertilizer granulator.
