玉米抗茎倒能力评价及理想株型

Evaluation of Stem Lodging Resistance and Ideal Plant Type of Lodging Resistant Maize Varieties

倒伏是影响玉米产量与品质的重要因素,是当前困扰农业机械化收获与农业集约化生产的重要障碍。本文对玉米倒伏影响因素进行了归纳,梳理并总结了玉米倒伏的研究方法与品种抗茎倒能力评价指标,并在此基础上提出了玉米抗茎倒品种的理想株型,为抗倒伏品种的选育与玉米的抗倒伏栽培提供参考。

Lodging is one of the important factors restricted maize yield and quality, and also is becoming great obstacle of modern intensive agricultural production due to restriction of mechanization harvesting. In this paper, factors which influenced maize stem lodging were analyzed, research methods of lodging and evaluation index of maize varieties with different lodging resistance summarized. Ideal plant type of stem lodging resistant varieties was put forward based on previous research. This will provide reference for higher lodging resistant maize breeding and cultivation.
