How to use the organic fertilizer production line to ferment cow dung to produce organic fertilizer


The organic fertilizer produced by cow dung contains a large amount of amino acids and organic matter, as well as nitrogen, phosphorus, potassium and other nutrients required for plant growth, which can improve the physical and chemical properties of soil and improve the continuous production capacity of soil. In addition, with the improvement of people's living standards, the demand for organic vegetables, fruits and other foods increases, The production of bio organic fertilizer by using the organic fertilizer production line of cattle breeding waste to realize the resource utilization of breeding waste has a broad application prospect in agricultural tax.

Organic fertilizer production line process of planting and breeding combination mode: the planting and breeding combination mode refers to the collection of feces by dry cleaning or water soaking feces. During the dry cleaning of feces, the solid feces are treated by composting or other harmless methods, and the sewage and part of the solid feces are treated by anaerobic fermentation, oxidation pond, etc. on the basis of nutrient management, organic manure, biogas residue, biogas slurry or fertilizer water are applied to field crops, vegetables, fruit trees, tea gardens, trees, etc; If the method of soaking feces is adopted, the feces are treated by anaerobic fermentation and oxidation pond, and then returned to the field for agricultural production. There are three key elements of the organic fertilizer production line adopting the combination of planting and breeding. One is to consider that the self owned land and available land of the farm can meet the requirements of fermentation, composting and storage; Second, considering the land bearing capacity, the demand for organic fertilizer will vary according to different crops. Generally, it is appropriate to absorb the feces and urine produced by one cow at 0.13hm2; The third is to consider the local natural climate conditions, because the temperature has an important impact on the fermentation of organic fertilizer.
