Embodiment 1

[0040] 100 kg of livestock and poultry manure, under the condition of stirring and proper heating, add dilute sulfuric acid with a weight content of 60%, and the addition amount is 8 kg of livestock and poultry manure; when the temperature rises to 70-80°C, the viscosity of the manure gradually decreases, and the color gradually decreases. When it is reddish-brown, add 3 kg of superphosphate, 1 kg of lime and 20 kg of coal ash, stir well, keep the material temperature at 70-90°C, react for 0.5-1 hour, then add 2 kg of humic acid and 2 kg of quartz powder and 0.3 kg of water glass, and stir evenly to obtain a crop synergistic fertilizer.

Embodiment 2

[0042] 1 ton of livestock and poultry manure, under the condition of stirring and proper heating, add dilute sulfuric acid with a weight content of 60%. When it is reddish-brown, add 10 kg of calcium superphosphate, 1 kg of lime and 300 kg of coal ash and stir well, keep the temperature of the material at 70-90°C for 0.5-1 hour, then add 10 kg of sodium humate, 10 kg of fine sand and 2 kilograms of water glass, stir evenly, obtain the crop synergistic fertilizer.

Embodiment 3

[0044] With 1 ton of livestock and poultry manure, under the condition of stirring and proper heating, add the amount of dilute sulfuric acid containing 60% by weight, and the addition amount is 20 kg of livestock and poultry manure; when the temperature rises to 70-80°C, the viscosity of the manure gradually decreases, and the color When it gradually turns reddish-brown, add 15 kg of calcium superphosphate, 1 kg of lime and 200 kg of coal ash and stir well, keep the temperature of the material at 70-90°C and react for 0.5-1 hour, then add 8 kg of sodium humate and 15 kg of fine sand And 3 kilograms of water glass, stir well, obtain the crop synergistic fertilizer.

Abstract

The invention discloses a method for rapidly converting animal-poultry faeces into high-efficiency fertilizer, which comprises the following steps: hydrolyzing animal-poultry faeces under the acidity condition and producing amino acid (ova and germina are all killed in the process) to obtain crop synergia fertilizer; adding hydrolyticre agent into dispersant, odor absorbent, adhesive-maintaining agent, coating agent and bulking agent. The fertilizer not only has good fertilizer efficiency, but also has good effects on the proliferation of microbes in soil, can avoid occurrence of the following situations that microbes in soil die out, salt is accumulated and soil is hardened as chemical fertilizer is misused; and the implementation of the method plays a positive role in agricultural non-pollution ecological production and industrial production.

Description

technical field [0001] The invention relates to a treatment agent for livestock and poultry excrement and a production method thereof, in particular to a method for harmlessly treating livestock and poultry excrement to make it a high-quality fertilizer for crops. Background technique [0002] At present, our country has begun to pay more and more attention to food safety. With the implementation of green food, pollution-free agricultural products, and ecological agriculture plans, the livestock and poultry breeding industry has developed rapidly. Livestock and poultry breeding has become an important way to increase agricultural efficiency and farmers' income. Due to the rapid development of the livestock and poultry breeding industry, the pollution of livestock and poultry excrement is increasing day by day. At present, there are more than 14,800 large and medium-sized livestock and poultry farms in my country (referring to pig farms with more than 10,000 heads, cattle far...
