In the season of summer corn topdressing, the author found that many farmers still have misunderstandings in corn topdressing, which are manifested in: 1, topdressing too late. Farmers are accustomed to topdressing before and after tasseling, but they do not know that they have missed the best time. 2, a bombardment type of topdressing. When planting, put all the fertilizer into the fertilizer once, or sprinkle all the fertilizer when pouring the head water. 3, Wang Tian topdressing. Regardless of the characteristics of corn growth, wait for the topdressing after rain. In the above three cases, it is difficult for corn to produce high yields. In order to obtain high yield of corn, first of all, we should understand the fertilizer requirement of corn: the corn seedling stage is the key period for phosphorus and potassium fertilizer, and the large flare period before the tassel is the critical period for nitrogen fertilizer. Secondly, the determination of fertilization amount should be based on the production of fixed fertilizer. Generally, the land with a yield of 700 kg per mu needs to be applied with 35 kg of urea, 15 kg of diamine, 20 kg of potassium sulfate, and a plot of more than 800 kg per mu. Farmyard manure and micro-fertilizers such as zinc sulfate and borax. Finally, during the fertilization period and method, all phosphorus and potassium fertilizers, about 20% of nitrogen fertilizer and zinc fertilizer should be applied as base fertilizer (fertilizer) at one time. Studies have shown that the rational application of base fertilizer (fertilizer) can increase production by about 15%. In the large bell period (1 - 1.5 m high), the application of nitrogen fertilizer should be about 60% of the total amount of nitrogen fertilizer. It is best to apply 20% nitrogen fertilizer after the tasseling. It is best to apply or ditch the hole at a distance of 10-15 cm from the corn root. Do not apply it. In case of drought, fertilization should be combined with watering. After the application of good fertilizer, the comprehensive tube can not be ignored. According to the field growth situation, drought and watering, integrated pest control, timely harvest in time to obtain the final high yield.
