The npk fertilizer production line produces inorganic fertilizers: mineral phosphate fertilizer, mineral potassium fertilizer, compound fertilizer, nitrogen fertilizer.
Trace element fertilizer: copper, iron, boron, zinc, manganese, molybdenum and other trace elements and beneficial element fertilizers.
Fertilizers produced by the bio organic fertilizer production line: compost, manure, biogas fertilizer, green manure, crop straw, cake fertilizer, humic acid fertilizer, amino acid fertilizer, commercial organic fertilizer, bone meal, agricultural and livestock processing waste, sugar mill waste, etc.
In order to ensure that the base fertilizer can adequately supply the nutrients for the growth of vegetables throughout the growth period, the method of mixing organic fertilizers with chemical fertilizers is often used in the base fertilizers. Usually, 20%-50% of the required phosphate fertilizer, potassium fertilizer, and 30%-50% of the nitrogen fertilizer are mixed into the organic fertilizer and applied together. The amount of chemical fertilizer should be adjusted according to the quality and quantity of the organic fertilizer used. On the one hand, adding biological bacterial fertilizer to the base fertilizer can better improve the soil and improve the absorption and utilization rate of nutrients; on the other hand, biological bacterial fertilizer can prevent root diseases and continuous cropping damage by bacteriostasis.
Chemical fertilizers should be used in conjunction with organic fertilizers, and macroelement fertilizers should be used in conjunction with medium and trace elements. The economic and rational application of nitrogen fertilizer should be determined according to the soil fertility level and the target yield. The application method should be applied deeply to reduce the volatilization loss and leaching loss of nitrogen. Phosphorus and potassium fertilizers should be applied on the basis of soil testing, with targeted application of trace elements, and the use of biological fertilizers is advocated.
At present, organic fertilizers come into being. The organic fertilizer manufacturing process: chicken and pig manure is used as the main raw material, a certain amount of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, magnesium sulfate, ferrous sulfate and other substances are added, and rice bran, yeast, soybean meal and sugar are added. Fermentation for a certain period of time as biological bacteria, under the action of sulfuric acid, mixed fermentation to obtain biochemical fertilizer, which has been widely used in production now.
