Avoid basal fertilizer deficiencies topdressing generation: the use of high-quality farmyard fertilizer as a base fertilizer, can increase soil organic matter and soil aggregate structure, provide the various nutrients needed for the growth and development of corn. Fertilizer does not have this advantage. "Insufficient base fertilizers and fertilizers" can only make the land more and more lean, more and more kind of consolidation. Avoid fat to chase, there is water to pour: in the seedling period before jointing, if not according to the degree of drought, good condition, the strength of seedlings and other practical conditions for top dressing, watering, often make the seedlings of the aboveground long, The underground roots are difficult to deepen, so that the seedlings lose the opportunity for seedlings to plant, and later lay down plant hidden dangers. Excessive top-dressing watering during the grain filling period increases investment and wastes fertilizer. It also causes corn gluttony to ripen and suffers from frost. Too much fertilizer and water: Fertilizer and water are big, although it is a prerequisite for high yield of corn. However, improper use is only harmful and unprofitable. In addition, fertilization should be determined based on the target yield. The target production is the amount of corn planted in the same year. It is determined by the level of soil fertility in cultivated land. In addition, according to the average yield of corn in the first three years of the plot, it can be increased by 10% to 15% as the target output of maize. For example: a plot of land with high fertility, when the planned corn production reached 600 kilograms, the total nitrogen, phosphorus and potassium nutrients needed for the whole growth period of corn were 15 kg, 7.2 kg and 12 kg, respectively. The reference target yield fertilization has great benefits in helping maize yield. Avoid attaching importance to nitrogen, phosphorus, potassium, light micro fertilizer: micro-fertilizer has a great influence on the growth and development of crops. Take zinc fertilizer, corn reacts very sensitive to it. Experiments have shown that: When applying zinc fertilizer to corn, the number of grains per ear can be increased by 50 to 80, the grain weight can be increased by 15 to 30 grams, the baldness rate can be reduced by about 50%, and the yield per mu can increase by 8% to 15%. Avoid bogey after heading: After corn heading, there are many plots due to under-application of basal fertilizer or the quality is not high, the efficiency of top dressing has been exhausted, resulting in nutrients in the soil can not meet the growth needs of corn. This urgently requires the application of some fast-acting N and P fertilizers to prevent premature senescence, promote grout and grain filling, and increase grain weight. In addition, the "seed-seeking fertilizer" should be applied early, acupuncture, and proper application.
