The npk fertilizer manufacturing process is mainly composed of a crusher, a fertilizer mixer, a granulator, a screening machine, a fertilizer coating machine, and an automatic fertilizer packaging machine. The npk fertilizer production line has high work efficiency and saves labor costs.
Compared with organic fertilizers, NPK fertilizers have higher content of NPK elements. Compared with organic fertilizers, NPK fertilizers have quicker effects. In modern agriculture, NPK fertilizers are absolutely necessary nutrients. The fertilizers produced by the npk fertilizer production line are made of powdered chemical materials containing nitrogen, phosphorus and potassium. How to improve the use rate of npk fertilizer and increase crop yield, the following are the things to pay attention to when fertilizing:
Apply more nitrogen fertilizer in places with good light conditions to promote the vegetative growth and reproductive growth of crops; in places with poor light conditions, apply less nitrogen fertilizer to prevent crops from greedy and late maturity; when the light is strong, apply deep fertilizer to prevent volatilization, For photolysis, more potassium and phosphate fertilizers should be applied to improve water utilization. Finally, with the increase of the crop leaf area coefficient, the fertilizer should be appropriately increased.
Due to different water source conditions and rainfall in different regions, there will be some differences in the technology of fertilization. Excessive application of nitrogen fertilizer should not be used in seasons with more rain to prevent crops from growing wildly and to prevent water pollution; during drought and little rain, potassium fertilizer and phosphorus should be increased in moderation. The utilization rate of water, and can play the role of increasing nitrogen with phosphorus; in the operation method, it should be noted that when the soil moisture is the highest, heavy fertilizer should be applied lightly, that is, the fertilizer concentration should be high, but the amount should be small, and it should be consistent with the crop. Plants are kept at a distance. When the weather is dry, it is advisable to apply light fertilizer and apply more water, or to increase the frequency of watering.
