1987年我们从日本三共株式会社引进了土茵消,分别在沈阳和海城的辽粳5号水稻秧田进行试验.结果表明:用30%土菌消水剂1000倍液,于播种前和揭膜后两次施药,每平方米喷3公斤药液,防治立枯病效果为96.7～100%,发病率由未施药的43.4～63%压低到0～2.1%.施药对照(65%敌克松1000倍液)防效为82～88%,明显不如土茵消防效好.土菌消不仅对立枯病防治效果好,而且对秧苗有明显的生理活性,喷土菌消的稻苗的株高、根长、根数、分蘖数都明显高于 In 1987, we introduced soil Yinxian from Sankyo Co., Ltd. in Japan and experimented on the rice seedling of Liaodai 5 in Shenyang and Haicheng respectively. The results showed that: 30% soil water dispersant 1000 times before sowing and exposing After spraying twice, spraying 3 kg liquid per square meter, the effect of controlling blight was 96.7% ~ 100%, the incidence was reduced to 0 ~ 2.1% from 43.4% ~ 63% % Diketone 1000 times) control efficiency of 82 ~ 88%, significantly less effective than the soil fire effect.Earth sterilizing effect not only on the damping-off blight, but also on the seedlings have significant physiological activity, spore soil elimination of rice Seedling height, root length, root number, tiller number were significantly higher
