摘　　要：郑单958、郑单14、郑单18是近年生产上推广利用的紧凑竖叶型新品种。试验从高产生理、植株特性等方面进行高产栽培的研究探讨,为大田生产提供理论依据,结果表明:郑单958、14、18表现高产,稳产,早熟。其原因:(1)叶面积指数变化合理,叶片持绿时间长,衰老慢;(2)叶片中光合色素,蛋白质和可溶性糖含量高,光合能力强;(3)过氧化物酶活性高,丙二醛积累少,光合效率高;(4)籽粒体积大,灌浆时间长,速度快,千粒重高。试验结果表明郑单14仍为最佳利用品种,建议各地大面积推广利用。种子生产注意保纯,以充分发挥该品种的增产潜力或品种优势,为社会增加更多的商品玉米和经济效益。Corn Zheng'dan number14, Corn Zheng'dan number18,Corn Zheng'dan number21 and Corn Zheng'dan number958 are compactness vertical leaf new variety utilized to popularize to use in recent years. From crop physiological biochemistry, of type characteristic, etc to study, Corn Zheng'dan number14 is the high yield, produce steadily, and early-maturing. Its reasons are:(1) The change of, Index of area of the leaf is reasonable, blade hold green long, and become old Slowly. (2) The only shut the pigment of chloroplast; protein and soluble candy are high. (3) Peroxide enzyme activation is high. Third 2 aldehyde is little, photosynthesis is high. (4) The seed grains of heavy volume is high, the time of forming a vesicle is long, a thousand is heavy and high.
