　　为找出倒伏对小麦生长和产量的影响，进行了两年小麦大风暴雨倒伏模拟试验.结果表明：小麦倒伏后，下部叶片开始枯烂，病虫害加剧，光合速率下降.倒伏越早，“背地性曲折”效应越显著，以抽穗期倒伏后“背地性曲折”最显著.灌浆中期以后，小麦“背地性曲折”效应消失，倒伏后的小麦不能抬头.产量分析结果表明：倒伏时间越早，有效小穗、穗粒数、千粒重越低，减产率越高.抽穗期倒伏，减产65．6％；开花期倒伏，减产50．4％；灌浆前期倒伏，减产40．7％；灌浆中期以后倒伏，减产率开始递减.灌浆中期和灌浆后期的减产率分别为29．5％和16．3％.减产率在灌浆中期是一个拐点，灌浆中期以前的倒伏对产量影响更大.因此，小麦抽穗期及其以后，发生大风暴雨天气时，应该及早做好倒伏防御和灾后补救，尤其是灌浆中期以前.

In order to find out the lodging on wheat growth and yield influence,the author carried out two years of gale rainstorm lodging simulation test. The results show that after wheat lodging,lower leaves were rotten,and plant diseases and insect pests increased,while photosynthetic rate decline. The earlier lodging,the“negative geotropism zigzag” effect was more significant. It is most significant in earring stage. Production analysis results showed that the lodging time earlier,the effective spikelet,grain number and thousand seed weight were lower, the higher the rate of production. Yield decreased by 65.6% in the early lodging stage and anthesis was 50.4%. In the middle of the grouting after lodging,reduction rate began to decline. The production rate of medium and late grouting stages were 29.5% and 16.3% respectively. Cut rates in pubertal distribution,in the middle of the grouting was a inflection point and it was more influence on yield. Therefore,wheat heading stage and later, People should take measures as soon as possible to lodging defense and post-disaster remedy,especially before in the middle of the grouting when wind storm weather occurs.
