为了提高大豆、玉米间作的产量及经济效益,1985—1987年我们在忻州市进行了大豆、玉米合理间作方式的研究,结果表明:大豆与玉米理想的间作方式是4∶2(4行大豆,2行玉米)或3∶2.行距均为25厘米.这样构成的复合群体空间排列较合理,组成作物的总群体适宜.比单种大豆或玉米 In order to increase yield and economic benefits between soybean and maize, we conducted a reasonable intercropping system of soybean and maize in Xinzhou City from 1985 to 1987. The results showed that the ideal intercropping system of soybean and maize was 4: 2 (4 rows of soybean, 2 rows of maize) or 3: 2 with a row spacing of 25 cm The composite groups thus formed are more spatially arranged and the total population composing the crop is more suitable than the single species of soybean or corn
