在河西荒漠灌区比较了小麦、玉米、大豆3种作物在连作、轮作、间作方式下的产量,结果表明,小麦产量以小麦与玉米轮作最高,为6839.3kg/hm2,较连作增产23.6%;玉米产量以小麦与玉米间作(小倒茬)最高,为12915.0kg/hm2,较连作增产50.8%;蚕豆产量以玉米与蚕豆问作(连作)最高。为3654.0kg/hm2,增产率达50.2%。

The yield of three crops (the wheat, corn, and soybean) in three cropping system (the continuous cropping, rotation and intercropping) in the hexi corridor desert irrigation was compared, the results showed that the yield of wheat in which wheat and corn intercropping (the rotation)is the highest, by 6 839.3 kg/hm2, increase 23.6% than the continuous cropping, the yield of corn in which wheat and corn intercropping (low-toxin chemical) is the highest, by 12 915.0 kg/hm2, increase 50.8% than the continuous cropping, the yield of faba bean in which faba bean and corn intercropping (the continuous cropping) is the highest, by 3 654.0 kg/hm2, the yield increase rate is 50.2%.
