Fertilization technology of cabbage

Cabbage is the biggest characteristic of disposable fertilizer fertilization: after transplanting until harvesting the entire growth process in no fertilization, no artificial watering, the normal growth of plants, and can achieve high quality and high yield. In the fertilization process is not affected by water conditions, thus saving water,water diversion, fertilizer amount of labor, reduce labor intensity, but also improves the utilization rate of fertilizer, reduce fertilizer loss, reduce the pollution of chemical fertilizer on cultivated land, atmosphere and Qilu Lake water. It is worth noting that:it’s most suitable disposable cabbage in summer and autumn, winter and spring drought season specific discretionary use.
Fertilizer selection and dosage: The whole growth period of cabbages will be used to apply to the fermented farm manure 800--1000K/ mu (or the refined organic fertilizer 300--500K/ mu)., 45kg urea, compound fertilizer:50kg(N:P2O5:K2O=15:15:15), calcium 5kg, potassium sulfate 4kg or application of special fertilizer per mu of cabbage 80-120kg.
Now, Let me introduce the NPK Fertilizer Production Line.
NPK Fertilizer Production Line
1. The NPK ( Nitrogen, Phosphorus and Potassium) Fertilizer Production Line is our manure products, they are running stable, the quality of them is high, and they are easy to maintence and repair.
2. The rate of being ball is high, outer recycle materials is few, the comprehensive energy consumption is low, no pollution and strong adaptability.
3.The setting of the whole production line is reasonable and within advanced technology, it could improve production efficiency, reducing the production cost and the production scale could be controlled easily.

Next,Let me introduce the major machine of the NPK fertilizer production line is Rotary Drum Granulator.
Drum granulator is a kind of fertilizer granulator machine can make the material into a specific shape. Drum granulator is one of the key equipment of the compound fertilizer industry. It is suitable for large-scale production of cold &hot fertilizer granulation line and high and low concentration compound fertilizer line. Main work method for aggregate wet granulation, through a certain amount of water or steam, the basis for fertilizers in the cylinder body after full wet chemical reaction, in a certain liquid under the conditions of the rotating cylinder with campaign, reunion between particles to produce extrusion pressure of material into a ball.
