摘要
采用室内沙培、温室盆栽和田间试验的方法研究了3种种衣剂对山农饲玉7号幼苗的安全性、病害防治及产量影响。结果表明:吡虫啉·戊唑醇5.4%种衣剂(药种比为1∶100)对山农饲玉7号幼苗期株高、初生根长和分蘖较其他2个种衣剂有显著促进作用。吡虫啉·戊唑醇5.4%种衣剂(药种比为1∶50、1∶100)对粗缩病和纹枯病防治效果分别达到93.5%、87.1%、80.0%、71.7%。测产结果进一步证明,吡虫啉·戊唑醇5.4%种衣剂处理平均产量达6891.9kg,增产率达11.5%,显著高于其他2个种衣剂处理。
The effects of protective function and yield of 3 seed dressings on shannong feed corn No.7 was studied with indoor experiment, greenhouse potting and field trial respectively. The results showed that Imidacloprid .tebuconazole 5.4% FS （medicament and seed quality ratio 1 ： 100） had remarkable promoter action compared with another 2 FS in plant height at seedling stage, length of primary root and tiller. The effects of Imidacloprid .tebuconazole 5.4% FS （medicament and seed quality ratio 1 ： 50 and 1 ： 100） for control of Rough dwarf of corn and Corn Sheath Blight were 93.5%, 87.1% and 80.0%, 71.7% respectively.The tests also proved that when the corn was treated with Imidacloprid .tebuconazole 5.4% FS, the average yield reached to 6 891.9 kg/mu and the rate of production increase reached to 11.5%, higher than others.
