摘要/Abstract

摘要： 本文以高粱籽粒高产为目的，采用适合于生产上的种植密度，对不同株高的粒用高粱品种、杂交种群体进行生产能力和逃命能力比较研究。研究结果表明，中秆杂交种具有最高收获指数，获得最高籽粒产量。但是，我国当前生产上种植的中秆杂交种都属于叶片宽长且平展的株型，在LAI较高的生育后期，群体过于郁蔽,透光通风不良,导致NAR

Abstract: In order to find an approach for higher grain yield, different types of grain sorghum were grown at a density similar to that of the farmer's field to study their productivity and photosynthetic capacity comparatively. The results indicated that medium-stalk hybrid sorghum had the highest harvest in
