连续两年 (1997～ 1998)的不同基因型玉米间作试验表明 :不同基因型玉米杂交种合理间作有利于高产和稳产。吐丝后叶面积指数大于相应的单作或增加幅度较大 ,绿叶面积持续时间长 ,对穗粒数、粒重提高显著 ,而且田间株高整齐度趋于一致。
Two consecutive years (1997 ~ 1998) intercropping experiments with different genotypes of maize showed that reasonable intercropping of different genotypes of maize hybrids was beneficial to high yield and stable yield. After silking, the leaf area index was larger than that of the corresponding single cropping or increasing amplitude, the green leaf area lasts for a long time, and the grain number and grain weight of spike increased significantly. And the uniformity of plant height and height in the field tended to be the same.
