摘　　要：2010年选取江汉平原9个代表性县市共12块超级杂交稻中稻田,于水稻拔节期喷施立丰灵,考查了水稻基部第一、二节间的粗度和长度变化。结果表明,喷施立丰灵后,11块试验田的稻株第一、二节间显著增粗与缩短,占总试验点的92%,说明立丰灵在江汉平原各县市不同生态条件下防止超级杂交稻倒伏具有较好的效果。12 mid-season rice fields with super hybrid rice in nine counties of Jianghan plain were selected as experimental field where Lifengling was sprayed at jointing stage.The diameter and length of the first and second elongated extension section between different treatments and CK was compared.The results showed that after spraying Lifengling,the diameter and the length of the first and second elongated extension section shortened and thickened in 11 of the 12 fields,accounting for 92%,indicating that Lifengling has general effect in preventing lodging of super hybrid rice under different ecological conditions in Jianghan plain.
