Organic fertilizer equipment production management technology of fermentation process

In the process of fermentation, the temperature control is very important.Temperature is too low, not up to the standard of the rotten;High temperature compost nutrient loss easily.From appearance to inside of temperature in the compost in 30 cm to shall prevail.Measuring temperature with a thermometer, therefore, it's a metal rod to longer than 30 cm, in the measurement, to be inserted in the compost above 30 centimeters, can correctly reflect the composting fermentation temperature.(1) the fermentation temperature and time requirements:After the manure, chicken manure into fermentation stage for the first time.It will automatically heating up to 55 ℃ above, lasts for 5 to 7 days, then can kill most of the parasitic ovum and harmful bacteria, meet free-pollution disposal standards.In three days over a heap of, this is good for ventilation, heat dissipation, rotten evenly.Fermentation in 7 to 10 days, the temperature natural dropped below 50 ℃, due to some species in the fermentation process for the first time will lose activity due to the high temperature, need a second fermentation.Again to join 5-8 kg of bacterial mixture, stir to mix well.Then time to control the moisture content is about 50%.Such as catch a chicken manure in hand, hold together and palms, damp fingers without water leakage, water right.The second fermentation temperature to control under 50 ℃, 10-20 days, after composting temperature dropped to 40 ℃, the following this to reach rotten standards.
(2), should be paid attention to in the process of fermentationMade in the process of biological organic fertilizer, the static method should be paid attention to:Cover the surface of the yeast in 10 centimeters or so finely straw or a layer of calcium superphosphate, can reduce the ammonia evaporation, avoid the nutrient loss.If encounter winds in the process of fermentation, the top to cover the breathable material such as straw, in order to reduce the loss of moisture evaporation and temperature.Livestock and poultry manure storage time is too long or manure, straw and weeds more, less waste, can add appropriately meal, urea or fresh chicken manure, increase the content of nitrogen, the high carbon and nitrogen ratio, speed up the fermentation, improve the quality of the fertilizer.Composting of the pH value should be controlled in 5.5 8.5, if compost pH value is lower than 5.5, is too partial acid, can be appropriately adjusted to add lime.Should be avoided during rainy season, the outdoor production of organic fertilizer, to avoid moisture is too high.Such as high moisture appeared in the process of composting fermentation, and permeability is bad, can be inserted in the middle of the fermentation of a few straw help breathe freely.When the color of the biological organic fertilizer is a dark brown or yellow-brown, internal surface of the organic manure composting with a lot of white mycelium, raw chicken manure, maggots, no smell, and with a slight ammonia odor, then made the static way biological organic fertilizer has reached the standard of rotten.Can be directly used in fields as basic fertilizer or fertilizer.With chicken manure are introduced more than small static production of biological organic fertilizer processing and manufacturing methods, farmers can according to the different source of dung, field size and the demand of the fertilizer, should according to, to reasonably arrange production.
