本文分析总结了紧凑型玉米品种的高产生理特征 ,与平展型玉米品种相比 ,它具有穗上叶与主茎夹角小 ,叶向值大 ,叶面积系数大 ,群体光合势高 ,库容量大 ,经济系数高等特点 ,这是紧凑型玉米品种高产的重要生理基础。同时针对当前紧凑型玉米超高产栽培中存在的几个问题 ,提出了紧凑型玉米的超高产栽培技术。
This paper analyzed and summarized the high-yielding physiological characteristics of compact maize varieties. Compared with the flat maize varieties, it had the characteristics of small angle between the upper ear and the main stem, large leaf orientation, large leaf area coefficient, high photosynthetic potential, Large, high economic coefficient characteristics, which is an important physiological basis for high yield of compact corn varieties. At the same time, according to several problems existing in the current ultra-high yielding cultivation of compact corn, the ultra-high yielding cultivation technology of compact corn was proposed.
