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。
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 .
