豫北地区夏玉米种植面积仅次于小麦,以其、株形紧凑、结实性好、耐密性好等特点,特别是全程机械化作业推广力度的加大,给夏玉米的稳产增产提供了较好的条件。但同时由于豫北地区季节性天气灾害的影响,不同玉米品种的栽种密度、田间管理等方面的差异性,而导致夏玉米倒伏倒折的现象依然不容忽视。为此,本文将从玉米新品种、合理密植、科学管理、化学调控等方面,来探讨夏玉米抗倒伏的技术措施。
The area of summer maize in North Henan is second only to that of wheat, with its characteristics of compact plant shape, good firmness and good confinement tolerance, especially the promotion of full-mechanized operation, which provides more stable yield and higher yield for summer maize Good condition. But at the same time, due to the seasonal weather disasters in the north of Henan Province, the planting density and field management of different maize varieties are different, leading to the phenomenon that summer maize lodging and descending again can not be ignored. To this end, this article will explore new varieties of corn, the rational close planting, scientific management, chemical control and other aspects to explore the summer maize lodging technical measures.
