Abstract：Using Xundan 20 (XD20,susceptible to lodging)and Xindan 68 (XD68,resistant to lodg-ing)as test materials,the lodging percentage,yield and its components under inter -and mixed -cropping systems were studied after lodging by strong wind.The results showed that the lodging percentage of XD20 un-der inter -and mixed -cropping with XD68 was lower than that under monoculture.The population yield of the inter -cropping XD68 and XD20 at the ratio of 2∶2 and 2∶4 were higher than that of monoculture ones. The population yields of mixed -cropping and inter -cropping at the ratio of 1 ∶1 were higher than that of XD20 monoculture but lower than that of XD68 monoculture.The yield per 666.7m2 of inter -cropping at the ratio of 2∶2 was the highest.
