根据1990～1992年进行的高产栽培试验，用Logistic方程拟合不同小麦品种的籽粒灌浆过程，并推导出一系列次级灌浆参数；用通住分析、逐步回归等统计方法分析了不同灌浆参数与粒重的关系。结果表明，籽粒灌浆速率和灌浆期持续天数是影响河南省高产小麦粒重的两个主要因素，灌浆速率的作用更大。进一步分析表明，灌浆快增期灌浆速率、持续天数和渐增期灌浆速率对粒重作用显著，且快增期灌浆速率、持续天数与渐增期灌浆速率密切相关。因此，提高渐增期灌浆速率对提高粒重尤为重要。
According to the high-yielding cultivation experiments carried out from 1990 to 1992, Logistic equation was used to fit the grain filling process of different wheat cultivars and a series of secondary grouting parameters were deduced. Through statistic analysis, stepwise regression and other statistical methods, The relationship between grain weight. The results showed that grain filling rate and grain filling duration were the two main factors affecting the grain weight of high yield wheat in Henan Province, and the effect of grain filling rate was greater. Further analysis showed that grain filling rate, grain filling rate and grain filling rate were significantly affected by grain filling rate, grain filling rate and grain filling rate during fast growing period. Grain filling rate and continuous days were closely related to grain filling rate in increasing period. Therefore, increasing the grain filling rate is particularly important for increasing grain weight.
