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 best sowing date of broomcorn millet in semi-arid region, four sowing dates were set up: comparative experiments on May 7, 14, 21 and 28 to study the effects of sowing date on the growth and yield of the barley millet. The results showed that sowing date had a significant effect on the growth and yield of Millet. Among them, the highest sowing yield, premature sowing or late sowing on May 14 would all reduce the yield. May 14-21 was the best sowing date for broomcorn millet in the western region of Heilongjiang Province. During this period, the temperature continued to rise steadily and the seedling grew stronger , Tidy plants, one thousand grain weight, high yield.
