通过研究冬小麦籽粒增重过程 ,对籽粒干物质积累过程中的阶段性和层次性给以划分 ,获取各阶段的动态特征参数。运用全息协调的方法对其动态特征参数进行研究 ,找出了其内在的协调关系 ,并给以定量优化。结果表明 ,小麦籽粒干物质积累量在快速增长期主要决定于持续天数 ,在渐增期和缓增期主要决定于灌浆的速率。 By studying the grain weight gain process of winter wheat, the staging and gradation of grain dry matter accumulation were divided and the dynamic characteristic parameters of each stage were obtained. The method of holographic coordination is used to study its dynamic characteristic parameters, and the inner coordination relationship is found out, and the quantitative optimization is given. The results showed that the accumulation of dry matter of wheat grains in the rapid growth period mainly depends on the number of days, in the period of gradual increase and slow growth mainly depends on the rate of filling.
