Compost fermentation is at this stage of organic fertilizer production and manufacturing in the use of a common way of fermentation. Whether it is compost fermentation on a flat surface or fermentation in a fermentation tank, in fact, can be considered a method of compost fermentation, corresponding to the use of fermentation tanks to carry out sealed aerobic fermentation. Compost fermentation is widely used because of its large output and small investment. Although compost fermentation seems very simple, but there are some points must pay attention to.
Pig manure and chicken manure fermentation of organic fertilizer need to pay attention to what aspects?
1. Raw material regulations: fermentation of raw materials, whether chicken manure, pig manure or big city sludge, need to ensure that fresh, of course, after the pile can not apply raw materials.
2. Auxiliary material regulations: raw materials moisture content is too high, pay attention to increase auxiliary materials, such as straw crushed, grain bran, etc.. And pay attention to the application of strong water absorption capacity, granules or length of suitable auxiliary materials, auxiliary materials granules are not suitable for too large.
3. Bacteria seedlings all over the uniform: aerobic fermentation bacteria is the important of compost fermentation. Generally speaking, a ton of raw materials must be added at least 50 grams of seedlings. Because the dosage is small, it is likely to be unable to joint distribution, fermentation bacteria seedlings can be added to the auxiliary materials early, mixed and proportioned and added to the raw materials, followed by grinding and polishing machine and other machinery and equipment to mix evenly.
4. Raw material moisture manipulation: compost fermentation of raw materials in the manipulation of water is a very critical step. Generally speaking, the moisture content of raw materials before fermentation should be 45-50% up and down. If you distinguish easy, is not to catch or loose. Can apply solid-liquid separator or add auxiliary materials in the raw materials to meet the requirements.
5. The total width of the fermented raw materials must meet the regulations. General provisions of the total width of fermentation materials more than 1 m 5, the relative height of more than 1 m, the length is not limited.
6. Rotate the actual operation regulations: rotate the actual operation of the purpose is to enhance the oxygen content of the raw material pile, manipulate the temperature in the pile, reduce the environmental humidity, for the aerobic fermentation bacteria growth and development of breeding to create the best standard, to ensure that the rotation is uniform and complete, rotate to ensure that the raw materials are still piled up, if the application of fermentation tank fermentation, can use the tank rotate the actual operation, if the compost fermentation on flat ground, should take into account the use of technology professional turning Turning machine, to ensure the effect and quality of the actual operation of rotation.
7. Fermentation temperature is a necessary condition for aerobic fermentation bacteria to grow and develop and reproduce. Fermentation temperature measurement, should be 30 ~ 60cm from the ground in the scope of the level inserted into the temperature table, inserted into the deep 30 ~ 50cm, read the value of smooth when the record temperature, record temperature without having to take down the temperature table. All normal fermentation, the ambient temperature of the area should be in the middle of 40-60 degrees. Only by maintaining this temperature, the raw material can be successfully fermented. If the temperature is too low, thermal insulation should be considered as a solution. If the temperature is too high, the raw materials should be rotated.
Pig manure and chicken manure fermentation of organic fertilizer need to pay attention to what aspects? After reading the above introduction you will understand it, biological organic fertilizer development prospects are very good, organic fertilizer not only can give crops a full range of nutrients, and long fertility, can improve and upgrade soil fertility, promote the breeding of microbial strains, enhance the physical and chemical properties of soil and biological activity, is a key nutrient element in the production and manufacture of green products.
