玉米空秆是指玉米植株不结果穗或有果穗而无籽粒的现象。在生产中,玉米空秆现象极为普遍,据调查玉米空秆率一般在2%以上,严重的可达20%~30%。空秆成为玉米产量提高的一个重要障碍。在多年的生产实践中本人总结了一些造成玉米空秆的原因及玉米空秆的预防措施,能有效减少玉米空秆的发生,提高玉米产量,促进农业增产增收。1玉米空秆的成因造成玉米空秆的原因很多,主要与植物生理、外界环境等因素有关。
Corn stalks refer to the phenomenon that corn plants have no ear or ear with no grain. In production, the phenomenon of corn stalks is extremely common, according to the survey of corn stalks generally more than 2%, severe up to 20% to 30%. Empty stalks become an important obstacle to increase corn production. In many years of production practice, I have summarized some of the causes of corn stalks and corn stalks prevention measures can effectively reduce the occurrence of corn stalks, increase corn production, and promote agricultural production increase. 1 causes of corn stalks cause of corn stalks for many reasons, mainly related to plant physiology, the external environment and other factors.
