摘　　要：选取荆州市具有代表性的4个水稻生产区域(监利、江陵、松滋、公安)进行大面积示范和小面积对比试验,探讨水稻抗倒剂立丰灵在大面积水稻生产上的推广应用效果。立丰灵均在水稻拔节期前1周施用,用量为450 g/hm2,对照试验喷施等量清水。结果显示,喷施立丰灵的大面积示范区水稻基部节间缩短增粗,并未出现水稻倒伏现象,江陵县对照试验中未喷施立丰灵的对照组水稻植株出现倒伏现象。以上结果表明立丰灵在大面积推广示范中具有良好的防止水稻倒伏的效果。One of PGR（plant growth regulators） in rice production,four representative districts of Jingzhou city（Jianli,Jiangling,Songzi,Gong＇an） in Hubei province were selected to study the effect of appliying Lifengling.The demonstrations on large-area and the comparison tests on small scales were conducted simultaneously.Lifengling was sprayed at the level of 450 g/hm^2 ahead of one week before the jointing stage.Water was used in the control group.The results showed that no lodging occurred in the demonstrations while some plants at Jiangling county in the control groups in the comparison tests were flattened.Lifengling shortened and thickens the basal intemodes of rice plants.It is indicated that Lifengling has good effect on preventing lodging of rice.
