摘    要:本文对三次多项式生长曲线模型进行了拓展研究,以干物质积累即时速度大于平均速度的起始点与结束点作为划分"S"型生长曲线三阶段(渐增期-快增期-缓增期)的起迄点,解析三次多项式模型,得干物质积累速度、时间等小麦灌浆特征参数方程,并得出几个常数结论.

关 键 词:三次多项式  生长曲线  干物质积累  灌浆规律  小麦

Abstract:The further study analysed the cubic polynomial growth curve model, according to the starting and ending points of dry matter accumulation instant speed being greater than the average speed as a division of the starting and ending points of "S" type growth curve( cumulative period--the fast growth period--slow growth period), grain filling characteristic parameters of equation such as the rate and time of dry matter accumulation, are obtained, and draw a few constants conclusion is drawed.
Keywords:cubic polynomial  growth curve  dry matter accumulation  grain filling characteristic  wheat
