摘　　要：研究了15％调环·烯效唑水分散粒剂的配方筛选和工艺，确定了助剂种类，得到了优化配方，并在水稻上开展了田间试验。试验结果表明，该产品润湿分散性好，悬浮率在80％以上，热贮合格，各项指标符合水分散粒剂的要求。在水稻拔节初期施用15％＇N环·烯效唑水分散粒剂18．0～22．5g／hm^2能降低水稻株高8．9％~14．6％，增产6．1％～8．0％，综合效果显著优于2种单剂，是值得开发和推广的水稻抗倒伏增产产品。The preparation method of prohexadione-calcium ＋ uniconazole 15% WG was studied. The results showed that the product had good dispersion ability in water with the suspension rate above 80%, and all of the specifications conformed to the requirements of WG. Prohexadione-calcium ＋ uniconazole 15% WG showed good efficacy. When prohexadione-calcium ＋ uniconazole 15% WG 18.0-22.5 g/hm^2 were used on rice at early jointing stage, the plant height of rice decreased 8.9%-14.6%, and grain yield increased 6.1%-8.0%.
