应用乙烯利(2-氯乙基磷酸)、KMS-1(3—(对氯苯基)-6-甲氧基—均三嗪—2,4(1H、3H)二酮三乙醇胺盐)、SC_2、4Pu等以不同组配方式对四川主栽品种绵阳11号进行杀雄效果试验和应用乙烯利、KMS-1各3000ppm混合液喷药方式杀雄效果试验。结果表明:(1)乙烯利、KMS-1各3000ppm混合杀雄是本试验中最佳药剂组配方式,比单一药剂喷施药害轻,杀雄后的植株相对不育率达99％以上,相对异交结实率达56.41％;(2)不同品种对药剂敏感性有差异,绵阳11号比80-8敏感;(3)乙烯利、KMS-1低剂量混用,总剂量相同,一次施与分次施杀雄效果无显著差异;(4)喷药后,株高平均降低7.07cm,穗颈缩短,但除单施乙烯利处理的穗子不能全部抽出外,各处理均全部抽出,不影响异交结实,穗长无明显变化。
Application of ethephon, KMS-1 (3- (p-chlorophenyl) -6-methoxy-s-triazine-2,4 (1H, 3H) SC_2, 4Pu and other combinations of different combinations of Mianyang 11 Sichuan Mianyang effect test and the application of ethephon, KMS-1 3000ppm mixed solution spray killing effect test. The results showed that: (1) The combination of ethephon and KMS-1 at 3000ppm was the best combination of pesticides in this experiment. Compared with the single agent, the relative infertility rate of the plants after killing was over 99% , Relative outcrossing rate was 56.41%; (2) The sensitivity of different varieties was different from that of Mianyang 11, which was more sensitive than 80-8; (3) ethephon and KMS-1 were mixed at low dose with the same total dose (4) After spraying, the plant height decreased by 7.07cm on average, and the neck of panicles shortened. However, all the treatments except for ethephon-treated ears could not be fully extracted. Affect outcrossing, spike length no significant change.
