At the same time, bio-organic fertilizer production line is used to produce bio-organic fertilizer, which contains a variety of functional microorganisms and rich organic matter, can improve soil structure, and play a role in nutrition, conditioning and health care for crop growth. In combination with chemical fertilizers, nitrate content in agricultural products was reduced accordingly. Experiments show that bioorganic fertilizer can reduce the average nitrate content of vegetables by 48.3-87.7%, increase the content of nitrogen, phosphorus and potassium by 5-20%, increase vitamin C, decrease the total acid content, increase the reducing sugar, and improve the ratio of sugar to acid, especially for tomatoes, lettuce, cucumbers and so on can significantly improve the taste of raw food parts. Therefore, the use of biological organic fertilizer, produce leaves color fresh, sweet taste, better to eat.
In the organic fertilizer production line, livestock manure organic fertilizer equipment is based on chicken and pig feces as the main raw materials, add a certain amount of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, magnesium sulfate, and other substances, with rice bran, yeast, soybean meal and sugar fermentation time, organic fertilizer can improve the soil, improve fertility. In addition, it is very important for organic fertilizer production process to match the fineness of raw materials in granulation. The fineness of the whole raw material should be matched as follows: 100-60 raw materials account for about 30%-40%, 60 mesh to the diameter of 1.00㎜ raw materials account for about 35%, diameter of 1.00-2.00㎜ small particles account for about 25%-30%, the higher the fineness of the material, the better the viscosity, the higher the surface finish of the granules after granulation. However, in the production process, the use of ultra-proportion of high fineness materials is easy to cause problems such as too large particles and irregular particles due to too good viscosity.
