Organic fertilizer harmless treatment technology
In organic fertilizers, some organic fertilizers, such as livestock and poultry excrement, are often accompanied by various viruses, parasite eggs, odors, etc. Some organic fertilizers such as weeds often carry various infectious diseases and seeds and seeds. And so on, so the organic fertilizers generally used for production are generally processed and become harmful without harm. At present, there are three methods for harmless treatment of organic fertilizers: physical methods, chemical methods, and biological methods. Physical methods such as exposure to sunlight, high temperature treatment, etc. have large loss of nutrients and high cost; chemical methods, such as the use of chemical substances, in the production of organic foods Can not be used; biological methods such as sterilizing and tanning after contaminating are the only methods that can be used in the production of organic foods. There are also many methods for stacking and degrading organic fertilizers in a harmless manner. We now introduce an “EM heap-up methodâ€. Organic fertilizer EM harmless heap method: Various organic fertilizers + rice bran, rice hulls + wheat straw (pulverized products) -> fully mixed evenly -> adjust the moisture content of about 30-40% -> the material tile height 20-30cm -> evenly spray EM more Functional Fermenter -> Cover transparent polyethylene film -> Temperature reaches 45-60. Turns 3-4 times at C—> produces white floc-like hair, no odor, which is the completion of the fermentation. (It can be completed in 3-5 days in summer, 10-15 days in spring, and 50 °C in winter to speed up the completion). After the fermentation is completed, it must be piled up for several weeks before it is applied. This will remove pathogens, eggs, grass seeds and odors, and at the same time it will allow the fertilizer to mature and improve the fertilizer efficiency.
