摘　　要：试验通过在水稻基部第2节间伸长1cm以内时,茎叶喷雾植物生长调节剂烯效唑与稻挺(30%矮.烯微乳剂),研究其对水稻抗倒性及产量的影响。结果发现,稻挺可显著矮化株高,缩短节间长度,降低倒伏率,提高水稻的抗倒伏能力。并且能提高水稻结实率和千粒重,水稻产量增加11.5%。研究表明,无论在控制倒伏性能,还是提高产量方面,稻挺均优于对照药剂烯效唑。When the second internode extend within 1 cm, the test researched lodging resistance and yield by using plant growth regulator uniconazole and Daoting （30% microemulsion）, the results indicated that Daoting can dwarf plant, shorten internode length, lower lodging, improved the lodging-resistant capability, it can increasing kernel setting and 1000-grain weight, increase the yield by 11.5%. The results indicated that the effect of Daoting were better than uniconazole on controlling lodging and increasing yield.
