| 摘 要： | 为实现良种良法配套、大面积高产,以当前山东省推广面积最大的品种济麦22为供试材料,采用裂区试验设计,进行该品种的播期播量研究。结果表明:播期、播量以及两者的交互作用对产量的影响显著,对产量构成因素有一定的影响;济麦22在鲁西南地区的适宜播期为10月9~15日,对应的适宜播量(基本苗,下同)为180.0万~270.0万/hm2;最佳播期为10月9日,最佳播量为基本苗180.0万/hm2。

| Abstract: | In order to accomplish high yield in large area successfully , Jimai 22 , the most popularized wheat variety in Shandong Province , was selected as material , and its sowing time and sowing rate were stud-ied by split plot experiment .The results showed that sowing time , sowing rate and their interaction all had sig-nificant effects on yield and certain effects on yield components .The suitable sowing time of Jimai 22 in south-west Shandong was Oct .9~15 ,and corresponding sowing rate was 1 800 000~2 700 000 plants per hectare . The optimum sowing rate and sowing time was 1 800 000 plants per hectare on Oct .9 . |
