为了研究30%矮壮素.烯效唑微乳剂对提高水稻抗倒伏能力和增产的效果,进行了两年的田间试验和全国多点药效试验。在拔节初期进行药液喷雾处理的结果表明:该30%矮壮素.烯效唑微乳剂能够显著降低水稻节间的赤霉素(GAs)含量,显著缩短水稻基部节间长度,增加节间粗度;提高节间单位长度干物质重,增强水稻抗倒伏能力;穗粒数增加8.3%～10.5%,空秕率降低3.8%～12.4%,水稻产量增加2.0%～5.3%。全国药效试验结果统计也表现出相似结果。表明30%矮壮素.烯效唑微乳剂具有防止水稻茎秆倒伏、增加产量的作用。
In order to study the effect of 30% CCC, the effect of unifoxazole microemulsion on enhancing the lodging resistance and yield of rice was tested in two years in the field and the national multi-point efficacy test. The result of spraying liquid medicine at the early stage of jointing showed that the 30% CCC microemulsion could significantly reduce the gibberellin (GAs) content in rice internode, shorten the length of basal internode and increase the internode The grain weight increased by 8.3% ~ 10.5%, the empty rate decreased by 3.8% ~ 12.4%, and the rice yield increased by 2.0% ~ 5.3%. The results of the national trial also showed similar results. The results showed that 30% CCA microemulsion had the effect of preventing rice stem lodging and increasing yield.
