Liaoning rice straw fermentation organic fertilizer project
With the increasing attention of the state to environmental protection, straw burning control has become an important part of the work of local governments. Liaoning region actively responded to the call of the state to promote the work of straw fertilizer return to the field, in order to realize the resource utilization of agricultural waste and ecological environment protection. According to local owners, due to land consolidation and transformation, as well as land improvement from drought to water, the land was changed from corn to rice during the consolidation period, producing a large number of rice stalks. Local owners hope to respond to the government's call to ban straw burning and straw fertilizer to return to the field and use rice straw resources to ferment into organic fertilizer. In this context, local owners find the environment of the Sea.
Mediterranean environment
Many years of first-line fermentation experience technical personnel into the site
China Sea environmental technicians arrived at the project site, made a preliminary understanding of the rice straw, and found that the rice had been truncated and crushed once during harvest, and only needed to add a certain amount of manure to adjust the carbon nitrogen ratio and water. The technicians with many years of first-line fermentation experience added a certain proportion of sheep manure and cow manure according to the nitrogen content and fecal sewage content, and fully mixed the rice straw and manure evenly. After mixing, it is transported to the fermentation tank by forklift.
Rice straw that needs to be fermented
Mix the finished material
The material is transported to the tank
NCS intelligent molecular membrane fermentation high-end equipment: After all the materials are transported to the fermentation tank, the film is covered and the edge is sealed. The film material is opened and covered outside the material and tank body, and the staff wear a rope to seal the hook. After commissioning the fan, the eardrum is normal, and the eardrum is normal in automatic mode. NCS intelligent molecular membrane fermentation high-end equipment has efficient and stable operation performance. After the fermentation parameters are set through the control cabinet, automatic management can be realized, which greatly reduces the difficulty of manual intervention and operation, and improves the production efficiency. The molecular membrane microporous structure in the membrane covering material can prevent the odor generated in the composting process from being discharged to the external environment, and can ensure the release of water vapor, and can also avoid the impact of external environmental changes such as rain and snow on the composting process, so as to achieve open-air fermentation, environmental protection and odorless.
Covered with molecular fermentation membrane
The fermentation film and tank body are edged
Material fermentation completed
After 20-25 days of high temperature aerobic fermentation, the film is uncovered and the material is discharged. At the discharge site, the whole material showed the characteristic color of brown fertilizer, the surface mycelium was dense, the material was loose, and it seemed to become a nutrient-rich organic fertilizer.
The fertilizer truck is spreading in the field
The owner of the project used a fertilizer truck in the paddy field to spread the fermented organic fertilizer. Straw contains rich nutrients such as carbon, nitrogen and phosphorus, and the organic fertilizer formed after treatment by NCS intelligent molecular membrane fermentation high-end equipment can provide nutrients to plants, improve soil quality and increase soil fertility. This approach can not only reduce the amount of fertilizer used, but also reduce pesticide residues and protect soil ecosystems.
