摘要
为探明自然风灾“布拉万”台风袭击后，玉米倒伏对根系和产量以及倒伏后绑扶的效果，测定了根系干重、产量以及产量性状。结果表明：郑单958和先玉335两个品种倒伏与未倒伏之间根系干重无明显差异；从根系干重平均值来看，郑单958根系干重较先玉335高100％，并且二者之间差异达到显著水平。2个品种在3个试验地不同倒伏程度减产幅度为0.5％～21.3％，平均减产为10.0％。玉米倒伏后不绑扶较倒伏后帮扶产量低5_3％，但二者之间差异不显著。
In order to investigate effect of lodging on root and yield of maize and the effect of binding after the natural disaster ＇Bolaven＇ typhoon, root dry weight, yield and yield characters were determined. The results showed that there was not significant difference of root dry weight between lodging and non-lodging for varieties of ＇Zhengdan 958＇ and ＇Xianyu 335＇. root dry weight of ＇Zhengdan 958＇ was 100% higher than that of ＇Xianyu 335＇, and the difference between the two reached significant level. Reduction of yield of different lodging ranged from 0.5% to 21.3%, the average was 10% for two varieties in three tests land. Maize yield of no binding after lodging was 5.3% lower than that of binding, but the difference was not significant.
