摘要
以新疆主栽玉米杂交种ＳＣ７０４为对照，对紧凑型玉米掖单１２号株型、叶片面积、功能期、光合势及冠层结构进行了系统的研究。研究结果表明，掖单１２号叶面积大、功能期长、不早衰、叶型系数小、株型紧凑，冠层内叶面积和光分布合理，可能是其获得增产的重要原因。
By contracting with the semicompact type maize,SC704 whqich was widely planted in Xinjing,the compact type maize,Yedan 12,was studied in its developing working period and photosynthetic area et al Based on the relationship between maize's plant type leaf developing and its production,factors of causing the production of Yedan 12 increasing were found
