为了确定半干旱地区糜子最佳播期，设置4个播种日期：5月7、14、21和28日进行对比试验，研究播期对糜子生长发育及产量的影响。结果表明：播期对糜子生长发育及产量有显著的影响。其中5月14日播种产量最高，过早或者过晚播种都会使产量下降，5月14～21日为黑龙江省西部地区糜子最佳播种期，这段时期气温持续稳定升高，幼苗长势比较强壮，植株整齐，千粒重高，产量高。

In order to determine the optimum sowing time of Panicum miliaceum L .in semiarid area ,the effects of different sowing dates on growth and yield of Panicum miliaceum L .were studied .There were four sowing dates treatments ,respectively on May 7th ,14th ,21st and 28th .The results showed that the sowing date had sig-nificant effect on the growth and yield .It could gain the highest yield when inseminate was on May 14th ,and it could make the yield decrease neither early nor late sowing .The best planting date in the western region of Heilongjiang province was on May 14th to 21st ,because of the temperature continued to rise steadily in this stage ,seedlings grew stronger ,plant tidy ,thousand kernel weight as well as yield was high .
