摘要/Abstract

摘要： 为修正冬小麦生长模型中的干物质分配,通过田间试验,对冬小麦干物质累积和在不同器官中的分配进行了描述.并且在此基础上结合文献资料,对冬小麦光合产物在各器官中的分配和转移系数的计算方法进行了探讨,分析了两者随相对发育阶段(RDS)的变化规律,并建立了函数表.同时运用试验资料进行了实地验证,取得较好的效果.

Abstract: Based on the field experimental data, dry matter accumulation and distribution among different organs of winter wheat were studied to modify the dry matter distribution of the winter wheat growth model. The calculating method of distribution and transition coefficient was introduced, and a function table between distribution coefficient and relative development stage was established. Meanwhile, the model was verified based on the experimental data, and the result was reasonable.
