【摘要】采用拌种和随水滴施2次的方法测定了2株芽胞杆菌对棉花黄萎病的防
治效果.结果表明,在滴灌条件下2株枯草芽胞杆菌对棉花黄萎病均表现出较好的防治作用,在小区试验中,S37和S44对棉花黄萎病的防治效果分别为29.86%和
42.81%,产量分别增加了25.22%和34.73%o.在田间试验中,S37在143团和147团的防病效果分别为51.3%和55.1%,增产效果分别达到7.43%和17.62%,844在143团和147团的防病效果分别为35.2%和39.3%,增产效果分别达到5.56%和15.51%.%In order to appraise the applied potentiality of Bacillus subtilis
S37 and S44 in controlling cotton Verticillium wilt, their control efficacy
was studied by seed dressing and drip irrigation in pot, plot and field tests.The results showed that the antagonistic strain S37 and S44 had better control efficacy (29.86％ and 42.81％, respectively) than the control under-mulch-drip irrigation, and significantly increased the yield by 25.22％and 34.73％.The field trials of antagonistic strain S37 showed that its control efficacy to cotton Verticillium wilt was 51.3％ in the regiment 143 and 55.1％ in the regiment 147, increasing the yield by 7.43％ and 17.62％, respectively.The field trials of antagonistic strain S44 showed that its control efficacy to cotton Verticillium wilt was 35.2％ in the regiment 143
and 39.3％ in the regiment 147, increasing the yield by 5.56％ and 15.51％, respectively.
