| 摘 要： | 利用4个当地主栽杂交稻品种与1个优质感病糯稻品种配置4个组合进行混合间栽组合控制稻瘟病试验。结果表明,不同品种混合间栽对稻瘟病具有较好的防治效果,间栽区各品种的平均叶瘟和穗瘟发病率均比净栽区低,尤其对优质易感病糯稻品种,穗瘟相对防治效果达到46.90%~77.36%。混合间栽较之净栽区可在一定程度上增加各品种的单位面积产量,平均增产幅度可达675.0~921.3 kg/hm2。 |

| Abstract: | Four combinations of different mixed inter-cropping patterns with four dominant hybrid rice varieties and one glutinous rice variety with a good quality and rice blast susceptibility were tested to investigate the effects of controlling rice blast. The results showed that the four combinations of different mixed inter-cropping pattern all had the better effects in controlling rice blast and the average disease rates of leaf blast and rice blast of different tested rice varieties in the mixed inter cropping plots were lower than those of the plots planted with a single rice variety, especially for the glutinous rice variety. The relative effect of controlling rice blast of mixed inter-cropping patterns was 46.90% -77.36% and the yield of mixed inter-cropping patterns was 675.0-921.3 kg/ha higher than that of planting a single rice variety. |
