| 摘 要： | 研究了不同防控技术对杂草稻的防控效果,结果表明：30％丙草胺乳油处理杂草稻株防效为14.27％～41.04％,1次50％瑞飞特乳油处理防效74.09％～91.15％;鲜重防效以2次处理最高;各处理水稻结实率增加9.53％ ～11.55％,实际产量增加28.9％～68.8％.其中,以水稻浸种剂浸种＋2次50％瑞飞特乳油处理的杂草稻防除效果最佳,水稻增产最显著.

| Abstract: | New technologies for the control of weedy rice in paddy fields were evaluated.Pretilachlor 30％ EC provided 14％ ～41％ control of weedy rice whereas pretilachlor 50％ EC sprayed once and twice controlled weedy rice between 37 ～87％ and 74 ～91％,respectively.Pretilachlor 50％ EC sprayed twice provided the best control based on the reduction of fresh weight.The seed rate was increased by 9.5％ ～ 11.6％,and the yield by 29％ ～69％.Control of weedy rice and crop yield increased significantly when new technology （rice soaking agent ＋ pretilachlor 50％ EC sprayed twice） was used. |
