| 摘 要： | 以杂交中稻组合川香优9838和K优17为材料,对冬水田区水稻直播技术进行了研究,形成了配套技术:每hm~2施纯氮120~150 kg(比大面积手插秧减少10%);川南3月10-15日播种,川北4月10-15日播种,比当地大面积地膜湿润育秧推迟7~10 d,每hm2用种量12~15 kg;播种后第2 d喷施直播稻专用除草剂,或3.5叶左右根据苗高情况灌水3 cm左右,用普通水稻田除草剂进行化学除草1次。

| Abstract: | The direct seeding techniques of hybrid mid-season rice in winter water-logged field were studied, using hybrid mid-sea-son rice combination Chuanxiangyou 9838 and K you 17 as materials. The direct seeding techniques of hybrid mid-season rice in winter water-logged field were as follows: the amount of nitrogen fertilizer is 120~150 kg/hm 2; sowing date in Southern Sichuan is March 10th to 15th and in Northerm Sichuan is April 10th to 15th, delayed for 7 ~10 days than the local large area film moist seedling, the sowing rate is 12~15 kg/hm2; spraying special herbicide at second days after sowing, or weeding one times with ordinary chemical herbicide at 3.5 leaves in 3 cm layer of paddy field. |
