The old variety of corn skillfully fertilized can also be high-yield. Wang Chengju, 52, is living in Wangxin Village, Liangshui Town, Liaocheng City. I heard that some experts have lectured and arrived at the venue early in the morning. The corn variety she planted is "958". In the past few years, the output has been around 900 kg. It can be seen that the high yield of corn of other races can reach 1400 and 1500 kg. What is the matter, she is very puzzled? “There are many factors for high yield of corn. Variety, fertilization, pest control and field management are all important. No one can do it.†Wang Jingyong explained. "958" is an old breed. In the past, corn cultivation has to be topdressed three times. Now, with advances in science and technology, controlled release fertilizers and slow-release fertilizers have been produced. Some farmers use a shell-and-fertilization method, and fertilizers and seeds are planted together. This method saves labor and reduces costs. The fertilizer is applied early and applied deep, and it is suitable for farmers who go out to work. However, the use of a shelling is not suitable for high yield of corn. In the middle and late stages, the nitrogen content is often insufficient and the yield is not high. If you want to produce high yields, you should still use the method of bottom fertilizer and topdressing, especially the topping of corn in the big bell period. Professor Wang Jingyong told her that if you want high yield, it is best to use Wofengkang as the base fertilizer, use four bags per mu, and use 10-15 kg of the ridge 24-10-5 or 22-9-9, together with the seeds. broadcast. In the case of corn 8-9 leaves, use 10 kg for top dressing, large bell mouth period, use 20 kg of potassium phosphate and 10 kg of urea. In the later stage, spray the foliar fertilizer containing medium and trace elements and humic acid. At the same time, it is necessary to do a good job in preventing and controlling insects in corn, strengthen field management, and eliminate weeding and summer water accumulation. In the final harvest, appropriate late harvest. In about 7 days, the output can be increased by 20%.
