Trace element fertilizer (hereinafter referred to as micro-fertilizer) refers to iron, zinc, molybdenum, manganese, copper, boron, etc., which play an important role in the growth and high quality of crops, but because of different micro-fertilizers and different crops. There are various special relationships between them. If they are applied blindly, they will not only achieve the desired effect, but they will often be counterproductive and even cause crop damage. In order to avoid disadvantages and achieve high-efficiency application of micro-fertilizer, it is necessary to make "three systems" and "two attentions" when applying.
It is suitable for different soil fertility conditions. Generally, the calcareous soil in the north, iron, zinc, manganese, copper, and boron are low in effectiveness and prone to lack; while in the acidic soil in the south, the effectiveness of molybdenum is low. Therefore, when applying micro-fertilizer, it should be reasonably applied according to the condition of trace elements in the soil.
Suitable for different crops. Various crops respond differently to different trace elements, with different degrees of sensitivity and different amounts of demand. For example, corn has a better effect on zinc fertilizer, rape is sensitive to boron, gramineous crops are sensitive to manganese, and legumes are sensitive to molybdenum and boron. Therefore, different trace elements should be reasonably selected for different crops and properly applied.
Suitable for different soil environmental conditions. Insufficient supply of trace elements in soil is often due to soil environmental conditions. The acidity and alkalinity of soil are the primary factors affecting the availability of trace elements, followed by soil texture, soil moisture, and soil redox status. In order to effectively solve the problem of lack or deficiency of trace elements, while supplementing trace element nutrients, it is necessary to pay attention to creating good soil environmental conditions, such as acidic soil. Soil acid and alkali can be adjusted by applying organic fertilizer or applying appropriate amount of lime. Sex.
Pay attention to the method of application. Everyone knows that crops require a small amount of trace elements, and many trace elements range from a lack to a moderate concentration. Therefore, when applying trace element fertilizer, on the one hand, the dosage should be strictly controlled to prevent the concentration from being too large; on the other hand, attention should be paid to key parts such as stems and leaves, and evenly sprayed on the front and back sides of the blade to prevent leakage. In addition, the micro-fertilizer can be evenly mixed into the organic fertilizer as the base fertilizer according to the application amount, and the effect is also obvious.
Pay attention to the application. Practice has proved that only when the crops meet the demand for a large number of elements (nitrogen, phosphorus, potassium), the application of micro-fertilizer can show a significant increase in yield. Therefore, in the application of micro-fertilizer, it is necessary to cooperate with the application of a large number of elemental fertilizers such as nitrogen, phosphorus and potassium to effectively improve the soil environmental conditions, achieve soil fertility and crop fertilizer balance, increase the effectiveness of trace elements, and thus improve Comprehensive utilization of various fertilizers to achieve high quality and high yield of crops.
