摘要

为研究干旱胁迫对夏玉米不同品种茎杆力学特性的影响，从茎杆力学特性角度探讨夏玉米品种的抗旱能力，以8个河南省主栽夏玉米品种为材料，比较干旱胁迫对茎杆抗折力、压碎强度、穿刺强度等抗倒力学指标的影响。结果表明，茎杆抗倒力学特性受干旱胁迫影响显著，平均下降15%~30%；受旱胁迫后，各品种茎杆抗折力、压碎强度、穿刺强度平均下降了26.1%、18.9%和16.8%；品种间差异明显，‘洛玉8号’、‘郑单958’降幅较小，而‘蠡玉16’、‘中科4号’降幅较大。研究结果表明‘洛玉8号’和‘郑单958’抗旱能力较强，而‘中科4号’和‘蠡玉16’抗旱能力较弱。

Abstract

In order to study the effect of drought stress on the stalk mechanical characteristics of different summer maize varieties and discuss the drought resistance ability of different summer maize varieties from the angle of stalk mechanical characteristics, the author used 8 main summer maize cultivars in Henan and analyzed the effects of drought stress on stalk break strength, stalk crushing strength and puncture strength. The results showed that drought stress had significant effect on stalk lodging resistance and the lodging resistance declined 15%-30% under drought stress. After drought stress, the stalk break strength, stalk crushing strength and puncture strength of different varieties averagely decreased 26.1%, 18.9% and 16.8%, respectively. Meanwhile, obvious differences existed among varieties, the average reduction of ‘Luoyu 8’ and ‘Zhengdan 958’ was smaller and that of ‘Liyu 16’ and ‘Zhongke 4’ was bigger. The research results showed that the drought resistance of ‘Luoyu 8’ and ‘Zhengdan 958’ was stronger and that of ‘Zhongke 4’ and ‘Liyu 16’ was weaker.
