To properly match the proportion of inorganic fertilizers and trace elements. Such as: organic fertilizer and inorganic fertilizer with 7:5 or 6:5 is appropriate; nitrogen, phosphorus, potassium with 1:0.5 ~ 0.6:0.25 ~ 0.3 is appropriate; micro-fertilizer for different crops, such as: cotton and rapeseed application Application of boron fertilizer, wheat, Corn, zinc fertilizer, molybdenum fertilizer applied to leguminous crops, application of boron, zinc, copper, iron and other trace fertilizers in melon vegetables and orchards have the effect of improving stress resistance, increasing production, and the like. To determine the best amount of fertilizer. Through the soil test, based on the principle of lacking what the soil lacks and how much it is lacking, the basic balance between the demand for fertilizer and soil fertility is achieved. To master the best fertilization time. General implementation of the principle of light, medium and heavy, after making up, so that the crop can not reach the early stage of fertilizer, medium-term is not crazy, the effect of not later de-fertilization. To effectively improve the fertilization method. Organic fertilizer is used as the base fertilizer. The nitrogen fertilizer in inorganic fertilizer should be applied deeply. The depth of fertilization should be 12 to 15 cm. The phosphorus, potassium and micro-fertilizer should be changed to fertilization in the last layer for full-layer fertilization, that is, 2/3 of the fertilizer amount should be used for plowing. Sprinkle on the ground, plow and then sprinkle 1/3 of the fertilizer on the hoe, and then after sufficient rake to make the fertilizer evenly distributed in the plough layer, in order to achieve the goal of increasing fertilizer utilization.
