为探讨伴生栽培小麦倒伏原因，以10个伴生栽培小麦基因型与10个普通栽培小麦基因型为试验材料．采用2种种植密度进行试验研究。结果表明：2个密度处理的10个伴生栽培小麦基因型倒伏率为100．0％，平均倒伏程度为54．1％，比10个普通栽培小麦基因型平均高90．0、51．3仓百分点，差异极显著。伴生栽培小麦与普通栽培小麦相比，抗倒指数低O．0156，达到极显著差异水平；基部第一、二节节间长度也比普通栽培小麦分别多1．9、5．8cm，均达到极显著差异水平；基部第一、二节节间粗度分别少0．84、0．73mm，也均达到极显著差异水平，因而导致伴生栽培小麦抗倒能力显著差。

In this paper, to investigate the factors of auxiliary tritieum aestivum lodging, ten auxiliary triticum aestivum genotype and ten ordinary triticum aestivum genotype were studied with two kinds of plant density.The results showed that, the lodging rate of the ten auxiliary tritieum aestivum genotype dealt with two kinds of plant density was 100.0%, the average lodging level was 54.1%,it was 90.0 and 51.3 percentage points higher than the ten ordinary tritieum aestivum genotype,the difference was significant.Compared with the ordinary triticum aestivum,lodging resistance index of the auxiliary triticum aestivum was 0.015 6 lower, it reached a significant level of difference.The length between the first and the second node of the basis section was respectively 1.9 cm and 5.8 cm more than the ordinary tritieum aestivum,whieh all had reached a significant level of difference.The roughness between the first ant] the second node of the basis section was respectively 0.84 mm and 0.73 mm less than it ,which all had reached a significant level of difference,leading to poor lodging ability of auxiliary tritieum aestivum.
