摘要
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。
Of six intercropping patterns in the experiment, the treatment with two rows of corn to threerows of soybean showed to be the best and yielded 326.5kg Of corn and 78.9kg of soybean permu respectively ,amount to 566.2kg per mu of standard grain .And its increase rate amounted to17%in comparison with single -cropping patterns gained from yield indexes reflect the relative number of luminous energy achieved by corn and soybean at their growth stages,and it is one ofscientific basis for the appraising the actual unit-yields of corn and soybean under different row-ratioes .
