| 摘要: |
| 本文根据施肥措施——营养体建成及衰亡——物质运转与分配——粒重形成的综合体系,研究了不同熟相小麦在粒重形成过程中各器官的一些主要生理性状的变化。从施肥及营养生理角度阐述了小麦不同熟相发生的原因和导致粒重形成差异的原因;并根据研究结果从理论上提出了高产条件下,争取正常熟相、提高粒重的合理施肥运筹体制。关于熟相的概念,除确定其形态色相表现之外,还根据粒重形成过程中的源、库、流关系,赋以新的内容。 |

| Abstract: |
| This paper is based on the comprehensive system of fertilizer practic- es,the establishment and senescence of vegetative organs,the pattern of transport and distribution of substance as well as the formation of grain weight for investigating the changes of some major physiological charact- ers of each organ of wheat plants with different maturing phases in the formative process of grain weight.From the point of view about fertilizer application and nutritional physiology,the reasons of occurance of differ- ... |
