| 摘 要： | 为探索间栽对优质糯稻控制稻瘟病和抗倒伏的有效途径,根据当地农业生产实际,选用2个籼型杂交稻和2个地方优质糯稻品种分别按4∶1的比例组成4个间栽组合,在湄潭县和雷山县进行了搭配种植控制稻瘟病和糯稻抗倒伏的田间大区试验.结果表明:籼糯搭配间栽种植能够较好地控制优质糯稻稻瘟病的发病率,提高防治效果,对糯稻抗倒伏有显著的作用,间栽糯稻叶瘟、穗瘟的发病率分别比净栽糯稻降低0.8%～1.6%和14.1%～15.4%,对叶瘟和穗瘟的平均防效分别达19.31%～50.17%和89.22%～93.30%,抗倒伏率达100%.

| Abstract: | Two hybrid indica rice varieties and two local glutinous varieties were intercropped to explore the effects on rice blast and lodge resistance of local glutinous varieties in Meitan and Leishan county.The results showed that the intercropping between hybrid indica rice variety and local glutinous variety could significantly reduce disease rate of rice blast and raise the lodge resistance of local glutinous varieties,the disease rate of local glutinous varieties under the intercropping model decreased by from 0.8% to 1.6%,and from 14.1% to 15.4% compared with that under the single cropping separately,the average control effect of leaf and panicle blast of two local glutinous varieties reached from 19.31% to 50.17% and from 89.22% to 93.30% respectively and its lodge resistance rate was up to 100%. |
