1. Control of dosage, concentration, and strive to apply even crops requires a small amount of trace elements, many trace elements from the lack to the appropriate concentration range is very narrow, therefore, the application of trace elements fertilizer should be strictly controlled dosage to prevent the concentration is too large, the application must Pay attention to uniformity.
2. For the application of trace elements in soils with different types and textures, the effect and content of trace elements are different, and the effect of applying trace element fertilizers is also not the same. The application of trace fertilizer should be reasonably applied to trace elements in soil.
3. Pay attention to the response of various crops to trace elements. Select various crops to respond to different trace elements. The sensitivity is different, the amount of requirements is also different, there are obvious differences in the application effect, such as the effect of zinc fertilizer applied to corn is better. Rape is sensitive to boron, cereal crops are sensitive to manganese, and leguminous crops are sensitive to molybdenum and boron. Therefore, reasonable selection and application should be made according to the sensitivity and fertilizer efficiency of different crops to different trace elements.
4. Pay attention to improving the supply of microelements in soil and soil, often due to the influence of soil environmental conditions. The acidity and alkalinity of soil is the primary factor affecting the effectiveness of trace elements, followed by soil texture, soil moisture, soil redox status and other factors. In order to completely solve the problem of lack of trace elements, while supplementing trace elements nutrients, we must pay attention to improving soil environmental conditions, such as acid soil can adjust the acidity and alkalinity of soil by applying organic fertilizers or applying appropriate amount of lime and improve soil nutrient status.
5. Note that with the application of a large number of elements of fertilizers, organic fertilizers, only if the crop meets the needs of a large number of elements such as nitrogen, phosphorus, potassium, etc., the trace element fertilizer can show a significant increase in production. The application of organic fertilizers can adjust soil environmental conditions to achieve the purpose of improving the effectiveness of trace elements. The combined application of organic fertilizers and inorganic microelement fertilizers should be an important measure for the management of soil microelement nutrients in agricultural production in the future.
