摘要
利用灰色关税分析．研究坡耕地玉米主要数量性状与产量（单株产量）的关系、结果表明：坡耕地高产玉米的主要特征是果稳长，行粒数多，穗行数和千粒重适中，果穗偏细．茎秆粗，叶片数适中，株高适宜，穗位低。
The relation between main guantitative characters and yield (seed weight per plant) in the maize of the land onthe slopes was studied with mathematical method of the grey incidence analysis of the grey system theory. The resultsshowed that high yielding maize of the land on the slopes gave longer ears.more line - grains number,Suitable earrows and 1000-grains weaight, thinner ears, thicker stems, Suitable leaves number, suitable plant beight and lowerear hight.
