为了探索不同小麦群体的发育特性和形态生理指标及其调控途径,我们曾于1960—1964年通过选用具有不同肥力水平的试验地和控制施肥量(主要是氮肥)的办法,造成高肥旺发低产、中肥壮发高产和低肥弱发低产三类小麦群体,以观察不同群体在形态结构、光强分布、干重积累、碳氮代谢、叶色
In order to explore the developmental characteristics, morphological and physiological indices of different wheat populations and their regulatory pathways, we used high-fertility fertilizers from 1960 to 1964 by selecting plots with different fertility levels and controlling the amount of fertilizers (mainly nitrogen fertilizers) Low-yielding, medium-fat and high-yielding and low-yielding and low-yielding three groups of wheat to observe the morphological structure, light intensity distribution, dry weight accumulation, carbon and nitrogen metabolism, leaf color
