摘  要：
以易倒伏玉米品种浚单20(XD20)和抗倒伏玉米品种新单68(XD68)为试验材料,研究了大风倒伏后不同间(混)作种植模式下玉米群体的倒伏率、产量及其构成因素。结果表明,XD20与XD68间(混)作群体的倒伏程度均低于XD20单作,在2∶2和2∶4间作模式下群体产量均高于其相应单作,混作和1∶1间作群体产量均高于XD20单作而低于XD68,在2∶2间作模式下单产达到最高。

摘  要：
Using Xundan 20( XD20,susceptible to lodging) and Xindan 68( XD68,resistant to lodging) 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 under 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.
