摘　　要：采用机械精量穴直播(以下简称机直播)、机直播+抗倒剂和人工手插3个处理对比,研究了抗倒剂立丰灵对机直播水稻的生育特性和产量形成特性的影响。结果表明,抗倒剂在一定程度上降低了植株的高度,促进了水稻植株的矮壮与抗倒性能;机直播+抗倒剂和机直播处理较人工手插处理显著地提高了结实率,在一定程度上提高了单位面积的有效穗数,实际产量分别增13.58%和10.00%,增产效果显著。Growth characteristics and yield formation of precision hill-drop drilling rice were studied by comparation among precision hill-drop drilling,precision hill-drop drilling ＋ lodging resistant agent lifengling with manual transplanting.The results showed that lodging resistant agent reduced the plant height to a certain extent,promoted the lodging resistance of rice plants;Compared with manual transplanting,seed setting rate of precision hill-drop drilling and precision hill-drop drilling ＋ lodging resistant agent was increased significantly;The panicles per unit area was improved to a certain extent as well;And the actual yield was 13.58% and 10.00% higher than manual transplanting respectively,yield was significantly increased.
