The phenomenon of empty stalks often occurs in field corn. In addition to congenitally infertile “male cornâ€, due to poor soil, high density, extensive management, lack of fertilizer and water, mechanical damage, pests and other undesirable factors affect the male and female organs. Differentiation affects the development of the ear and produces empty stems. Practice has proved that skillfully applying young ear differentiation fertilizer, heavy panicle fertilizer and foliar fertilizer, basically can prevent the phenomenon of acquired empty culm, so that corn can obtain high quality and high yield. 1. Appropriate fertilization of young panicle-differentiated fat corn. Mushi urea is about 5 kilograms, which can effectively increase the number of grains and the number of grains per row. This lays the foundation for raising panicle and ensuring the yield. For the thin, culm yellow maize, should be 3-5 kg ​​of potassium dihydrogen phosphate, open the ditch applied in the interline, to achieve the purpose of nitrogen, phosphorus and potassium to optimize the formulation of fertilization. 2, heavy panicle fertilizer before heading 5-7 days should be heavy ear fertilizer, Mushi compound biological fertilizer 25-30 kg, or urea 5-10 kg of urea, superphosphate 20-25 kg, potassium chloride 4- 5 kilograms, strive for full-grain panicles and strive for double ears. 3, clever application of foliar fertilizer from the joints of corn, with 0.3% of potassium dihydrogen phosphate and 0.1% of zinc sulfate mixed solution 50 kg, sprayed 2-3 times, each time interval of 7 days, you can also avoid empty stalks , play a very good effect of increasing production.
