| 摘 要： | 通过对前郭灌区水稻播种时期的研究表明:①前郭灌区水稻最佳播期:浸种催芽播种以4月18日为宜。②播种期较传统播期延后7～10 d,每天可节约费用(用水、人工等)100元左右。③最佳播期的秧苗白根多,粗且有根毛,叶距短,茎叶弹性好。④最佳播期的秧苗发病明显轻,秧苗返青快(基本无返青期)。⑤最佳播期的秧苗,秋后产量高。

| Abstract: | The sowing time were researched in Qianguo irrigation area and the result indicated: 1.The optimal sowing time were April 18th,2.A delay of 7-10 days on sowing can save 100 yuan from water using and man-power,3.The roots flourishing,the root hair and thick can be achieved by optimal sowing time,4.The optimal sowing time can reduce seedling disease and fast green return,5.It can achieve high yield by the optimal sowing time. |
