Trace element fertilizer: copper, iron, boron, zinc, manganese, molybdenum and other trace elements and beneficial element fertilizer.

Biological organic fertilizer production line fertilizer: compost, manure, biogas fertilizer, green fertilizer, crop straw, cake fertilizer, humic acid fertilizer, amino acid fertilizer, commercial organic fertilizer, bone meal, agricultural and livestock processing waste, sugar factory waste, etc

In order to ensure that the base fertilizer can adequately supply the nutrition of the whole growth period of vegetables, the method of organic fertilizer mixed with chemical fertilizer is often adopted in the base fertilizer. Usually the required phosphorus fertilizer, potash fertilizer 20%-50%, nitrogen fertilizer 30%-50% mixed into organic fertilizer. The amount of chemical fertilizer should be adjusted according to the quality and quantity of organic fertilizer used. On the one hand, adding bio-bacterial fertilizer to the bottom fertilizer can improve the soil better and improve the utilization rate of nutrient absorption; On the other hand, biologic fertilizer can play a role in preventing root disease and crop damage by bacteriostasis.

Fertilizers should be used in combination with organic fertilizers and large amount of elemental fertilizers with medium and trace elements. The economical and reasonable application of nitrogen fertilizer depends on the soil fertility level and the target yield. In the application method, deep application should be applied to reduce nitrogen volatilization and leaching loss. Phosphorus and potassium fertilizer should be applied on the basis of soil measurement, and microelements should be applied in a targeted way.

Organic fertilizer arises at the moment, organic fertilizer production process: chicken and pig feces as the main raw materials, add a certain amount of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, magnesium sulfate, ferrous sulfate and other substances, to rice bran, yeast, soybean meal and sugar fermentation for a certain time as biological bacteria, under the action of sulfuric acid, mixed fermentation to produce biological fertilizer, now in the production has been widely used.
