摘要
运用随机区组试验对玉米与大豆不同间作方式进行研究 ,以期获得不同间作方式对玉米产量影响最大的间作方式的表现。结果表明 ,玉米间大豆 2∶4的间作方式因间作比例适宜对自然资源利用较好 ,两者间的负作用小 ,其产量潜力得到了充分发挥 ,经济效益最高 ,总产值为 5 81元·6 6 7m-2 ;2∶4的间作方式分别比 1∶2、3∶2的总产值高出 91 9元、33 4元 ;1∶2、3∶2的大豆产量明显低于 2∶4。因此在玉米与大豆的间作中 。
The intercropping patterns of soybean and corn have been studied by using random experiment plots,in order to find which intercropping pattern could influence corn yield mostly.The results showed that the interplant mode 2∶4 of corn and soybean was better in use of natural resources.The corn yield could be increased because of lower negative effects between these two crops during their growing season.The total value of crop production reached 581 yuan·667m^(-2),which was 91.9 yuan and 33.4 yuan higher than the interplant modes 1∶2 and 3∶2 respectuiely.An appropriate interplant mode would be likely a key technique to increase crop yield as a whole.
