通过对四川几个优良小麦品种籽粒灌浆过程的Logistic方程有关参数及茎叶干重动态变化的分析，提出了四川优良小麦品种选育中主要灌浆参数的建议指标，其中T（灌浆持续期）为45d左右，R（平均灌浆速率）不小于每天2.2％，Rmax不小于每天4．0％。分析同时表明，四川早熟小麦品种具有更多的优良灌浆特性。
Based on the analysis of logistic equation and dynamic changes of stem and leaf dry weight in grain filling process of several fine wheat cultivars in Sichuan Province, the recommended indexes of main grouting parameters in elite wheat varieties breeding in Sichuan were put forward. Among them, the duration of T 45d or so, R (average filling rate) is not less than 2.2% per day and Rmax is not less than 4.0% per day. Analysis also showed that Sichuan early maturing wheat varieties have more excellent grain filling characteristics.
