贵州省广泛应用的玉米大豆间作方式的不同间作比例均优于单作。试验的６种方式中以２：３较好，亩产玉米３２９．５ｋｇ，大豆７８．９ｋｇ，折合标准商品粮５６６．２ｋｇ，比单作增产１７％。根据产量指数比较所获得的各间作比例的６种光合份额值，反映了玉米和大豆在生育期分别获得的光能相对数量，是评价不同间作比例的玉米及大豆实际单产的科学依据之一。
The proportion of different intercropping methods of maize and soybean intercropping widely used in Guizhou Province was better than single cropping. Among the 6 ways tested, 2: 3 is better, yielding 329.5kg of corn and 78.9kg of soybeans, equivalent to 566.2kg of standard commodity grain, 17% more than that of single cropping. According to the yield index, the six photosynthetic share values of each intercropping system reflect the relative quantity of light energy obtained respectively during the growth period of maize and soybean. It is one of the scientific bases to evaluate the actual yield of different intercropping corn and soybean.
