摘要
在长期定位试验的基础上,研究了不同化肥施用处理对夏玉米籽粒灌浆进程的影响。结果表明,籽粒干物质积累过程呈S型曲线,可用logistic模型进行模拟,相关系数均达0.99以上。随着化肥用量的增加,最大灌浆速率的持续时间延长,灌浆进程延长,千粒重提高。
The experiment was conducted at Hengshui experimental research farm in 2006. The results indicated that： The grain dry weight accumulation could be discribed by logistic model. And the coefficents was over 0. 99. The time of max filling rate was extention and the time filling was more longer and 1000 grain weight was more with increase amount of chemical fertilizer.
