Fertilizer equipment to explain the biological treatment of organic fertilizer

At present, organic fertilizer harmless treatment mainly physical methods, chemical methods and biological methods of three. Physical methods such as exposure, high temperature treatment, chemical method is to use chemical substances (in organic food production can not be used), biological methods such as inoculation after the fry and retting.
    Biological method
    The use of biological methods of organic fertilizer for harmless treatment, the new concept of fertilizer is what fertilizer in the organic food production process is most commonly used. Due to the use of different microorganisms, organic fertilizer harmless treatment of the heap, retting method there are many.
    Decoction
    Heaping technical essentials is "water foot, medicine uniform, sealed". Water foot: according to the ratio of straw and water 1: 1.7, so that the straw soaked, to ensure that the fermentation period of water needs. Drug uniform: according to the amount of straw after the wet 0.12% Shi full of decoction, spray evenly spray, while spray side mixing. Seal: the straw after the application of piled up to 1.5 meters wide, 1 meter high straw pile, filming real, with soil and mud seal, mud thickness of 2 cm.
   2. Enzyme composting
    Ingredients ratio is straw: bran: calcium magnesium phosphate: enzyme bacteria expansion bacteria: brown sugar: dry chicken manure = 50: 6: 1: 0.8: 0.1: 20 (raw material kg, not a percentage). Will be bran, calcium magnesium phosphate, brown sugar, enzyme bacteria bacteria mixed evenly, and then together with chicken manure spread in the water soaked straw, mix well after the pool in the pool, a little repression, observe the daily compost temperature, humidity. Suitable stacking temperature is 60 ~ 65 ℃, humidity is 50% ~ 60%. Composting was dark brown rotten state and there is no smell of lust, that is, the accumulation of enzyme composting composting.
    3. Multifunctional fermenting bacteria
    Mix all kinds of organic fertilizer such as rice bran, rice husk and wheat straw (crushed) fully mixed → adjust the moisture content of 30% to 40% → the material tiling height of 20 to 30 cm → uniform spraying "EM multi-functional fermentative bacteria" → Covered with transparent polyethylene film → temperature reached 45 ~ 60 ℃ when the flip 3 to 4 times → produce white flocculent hair, no odor, that is, the fermentation is completed. Summer 3 to 5 days to complete, the spring 10 to 15 days to complete, the appropriate winter plus 50 ℃ warm water to speed up the completion. After the completion of the fermentation is still a few weeks after the re-application, so that the pathogen, eggs, grass seeds to kill, remove the odor, while fertilizers can be cooked to improve fertilizer efficiency.
    4. Self-made fermentation ripening ripening method
    According to the weight of rice bran 14.5%, oil 14%, 13% bean, sugar 8%, 50% of water, 0.5% of the proportion of yeast, the first sugar in the water and stir dissolved, and then add rice bran, bean dregs, meal and yeast , And the fermentation was carried out at a temperature of about 30 ° C for 45 days. Finally, the ratio of 1: 1 was used to mix and dilute, and the mixture was uniformly stirred to prepare a ripening powder. The feces and straw and other bulks by 10: 1 ratio of the mixture, each 100 kg of mixed fertilizer by adding 1 kg of ripening powder for cutting rot. The accumulation of 10 days to carry out a number of trough turn into the machine, and then another 10 days for the second turn, and then a week, composting is completed.
    The harmless treatment of organic fertilizers is the need for environmentally friendly agriculture and the need for sustainable development of agriculture. For the harmless treatment of fertilizer, should be in accordance with the Chinese agricultural network to adapt to local conditions, follow the principle of non-toxic, harmless, non-polluting, the use of reasonable treatment, must not cause new poison and new pollution.
