Efficient treatment of chicken manure: fermented organic fertilizer

Chicken manure is a relatively high-quality organic fertilizer. The feed intake of chickens is not completely digested. About 40%-70% of the nutrients are excreted from the body. Chicken manure therefore has the highest nutrient content in all livestock manure. Rich in nutrients, including crude protein 18.7%, fat 2.5%, ash 13%, carbohydrate 11%, fiber 7%, nitrogen 2.34%, phosphorus 2.32%, potassium 0.83%, respectively 4.1 times, 5.1 times that of pig manure And 1.8 times. However, chicken manure is directly applied to crops without being treated or decomposed, and there are great harms and hidden troubles: direct application in the soil, fermentation under suitable conditions and generate a lot of heat, burning the crop roots. At the same time, chicken manure itself has a large number of pathogens, which brings diseases potential hazards to crops. Therefore, it is necessary to extinguish the chicken manure through the high-temperature decomposition of the nutrient fertilizer, the presence of parasites and eggs in the chicken excrement, and infectious pathogens through the process of decomposing (tanning) to achieve complete non-pollution. After disease-free, fertilize crops.

Chicken manure fermentation organic fertilizer method:

one. Rapid Fermentation (Kambab Fertilizer Fermentation):

1. Dosage.

One ton of organic material (about 2.5 tons of fresh material) plus one kilogram of fermentation auxiliaries, uniform stirring, fermentation. However, due to the high ratio of carbon/nitrogen, some raw materials that are more difficult to ferment, such as bark, sawdust, etc., can increase the dosage according to their actual conditions. Chicken excrement is also the same reason. Dilution: Add 5-10 kilograms of rice bran, corn or bran per kilogram of the starter, stir it evenly and then sprinkle it into the prepared material.

2. Mix and ventilate.

The golden baby starter is an oxygen-consuming organism, so in the process of operation, it must be frequently tumbling and stirring to achieve sufficient supply of oxygen. Otherwise it should produce odor, fermentation failure.

3. Carbon oxidation

The ratio of carbon and nitrogen in fermented feed should be maintained at 20-25, and the pH should be adjusted to 6-8 (ph).

4. Moisture.

The suitable moisture in the fermentation process is very important. It should be kept between 60% and 65%. It should not be too wet. It can be used to grasp a handful of materials and spread it without the need of dripping.

5. Temperature.

The temperature of the fermented feed should be maintained between 15 and 70 degrees, and the starting temperature should preferably be controlled at about 15 degrees.

6. Finish.

The fermentation time is about one week, but the raw material fermentation time will also change slightly. In the middle of fermentation, if there is a white hyphae, it is normal fermentation. In the later period, the temperature will remain unchanged, and the fermentation material will be dark brown and lightly pulled off, and there will also be nine tastes of earthy smell.

two. Fermentation pond Fermented chicken manure Organic fertilizer Large-scale farm Raw chicken manure Rin chicken manure Treatment: The chicken manure Fermentation Fertilizer is put into the chicken manure pool of the farm, and the chicken manure pond is filled up as the standard. The farm chicken manure flows into the chicken manure pool In the process, chicken manure is pumped into the chicken manure dehydrator to control the chicken manure within 50%;
The chicken manure with the water content below 50% and the auxiliary material sawdust%, zeolite powder%, humic acid (brown coal) 5%, rice husk 5%, in proportion with a forklift and mixed with a forklift to chicken manure fermentation Pool. Chicken feces is thrown once a day and the broth is evenly sprayed, and it is fully decomposed, sterilized, deodorized, and dewatered by pool-type aerobic continuous fermentation. The moisture content of the decomposed material is generally in the range of 30-35%, so that the mature chicken manure is fermented by 10 to 15 days of raw chicken manure, which is screened by a chicken manure screening machine and further dried to produce powdery ones.

For example, farms raise 100,000 chickens, chicken manure fermented to produce organic fertilizers, and supply 3 fermentation tanks (or 4 fermentation tanks, depending on the length of the fermentation tank). It is completed by a chicken manure fermentation and turning machine and a moving vehicle. The turnover of each fermentation tank. Every day, organic solid waste and plant stalks and other auxiliary materials and fermentation bactericides are formulated according to the formulation requirements. After being thoroughly mixed by a forced mixer, the forklift truck is evenly fed into the front of each fermentation tank (the front of the original empty tank is 1/8 or The front of the pool vacated after turning is 1/8) and is turned twice a day. The thickness of the fermented material in the pool is 1.5-1.6m. Continuous aerobic fermentation is conducted by forced air ventilation of the high-pressure fan and the oxygen provided by the contact of the materials with the air during the turning, so that the fermentation material is quickly decomposed, sterilized, deodorized, dewatered and dried. The fermentation cycle is 7-8 days.

Chicken manure fermented organic fertilizer not only has no odor, no burning root, no burning seedlings, and fermented chicken manure is rich in humus and other high-molecular complexes, and can form soil aggregate structure that is most effective for the growth of crop roots, and prevents soil compaction. Fertility and fertility have a positive effect on improving fertilizer utilization and absorption of nutrients so as to save fertilizer costs.
