摘要: 1994年在河北省衡水市邓庄中加合作试验站,结合田间试验对不同管理措施下冬小麦的灌浆过程进行了研究。结果表明:粒重的大小主要取决于灌浆时间和灌浆强度,小麦子粒的灌浆过程可用Logistic函数描述。小麦生长前期的水分胁迫有利于加快其发育过程,促使早抽穗灌浆。灌浆期较好的水分状况可延缓小麦的灌浆进程,但较大灌浆速率持续的时间较长,千粒重的潜力值较大。小麦的群体密度是影响收获千粒重的主要因素之一,随着穗密度的增大,灌浆速率和千粒重逐渐降低。随着施N量的增加,小麦的千粒重降低,这主要与施N的增穗作用有关。

Abstract: This study was conducted at Deng zhuang Experimental Station, Hengshui City, Hebei Province in 1994. The kernel filling process of winter wheat was observed. The results showed that the kernel weight mainly depended on length and strength of kernel filling period. The kernel filling process could be described by Logistic function. The beginning and peak of kernel filling could be delayed with better soil moisture condition. The highest kerne-l filling rate decreased as plant population increased.

Key words: Winter wheat, Kernel filling , Logistic model, Field management
