本文分析了不同栽培条件下的水稻株形变化规律,指出了株形的变化在一定程度上反映了生理性状的变化。采用合理的栽培措施进行系统控制,在保证必要穗数的前提下争取大穗,并相应控制倒3叶长度,促进穗长和剑叶长度,增加叶厚使上部叶片直立,下部叶片相对平展,使粒叶比达到最适程度,有利于改善株形,提高产量。
In this paper, we analyzed the changes of plant shape under different cultivation conditions, and pointed out that the changes of plant shape reflect the changes of physiological traits to a certain extent. The reasonable cultivation measures were used to control the system. Large spikes were obtained under the premise of ensuring the necessary number of spikes, and the length of inverted 3 leaves was controlled accordingly. The length of spike and the length of flag leaf were increased. Increasing the leaf thickness made the upper leaves erect and the lower leaves relatively flat, To achieve the optimum degree of grain-leaf ratio, is conducive to improving plant shape, increase production.
