Prepare fertilizer fermenter according to the weight of the material to be fermented 0.1% (i.e., one thousandth); with fresh rice bran (note: "rice bran" is not "chaff", rice bran nutritious and permeable are good, old rice bran or chaff nutrition is poor) will be diluted (every 1 kg fermentation aid plus 5 kg of rice bran). Poor, are unfavorable) will fermentation agent dilution (every 1 kilogram fermentation aid plus 5 kilograms of rice bran).
Two, adjust the water
The adjustment of water pay attention to the first less add, fast close to the requirement (65%), slowly add again, prevent the water excess exceeds the standard, in case of adding water excess exceeds the standard, can add the dry material to adjust again.
The raw material 65% moisture judgment method: the hand gripped the material, see the water does not drip, fall to the ground can be dispersed. In fact, 65% of the moisture does not show too wet, please pay attention to the correct judgment.
Three, build pile.
After the preparation of materials while spreading bacteria to build a heap, the heap height and volume can not be too short and too small, the requirements: heap height of 1.5 to 2 meters, 2 meters wide, the length can be freely adjusted according to the amount of fermented materials, at least not less than 2 meters.
Four, mixing and aeration.
Fertilizer fermenter is (consume) oxygen fermentation, so it should increase the oxygen supply measures to achieve the mixing, turn over diligently, aeration is appropriate. Otherwise, it will lead to anaerobic fermentation and produce odor, affecting the effect.
V. Temperature.
Starting temperature is preferably above 10 ℃ is better (four seasons can be operated, not affected by the season, winter try to ferment indoors or in the greenhouse), fermentation heating control in the 70 ~ 75 ℃ below is appropriate.
Sixth, finish.
The 2nd-3rd day when the temperature reaches 65 ℃ or more should be tipped, generally within a week can be fermented to complete, the material is dark brown, the temperature began to fall to room temperature, indicating that the fermentation is complete.
