| 摘 要： | 2002—2003年分别在吉林省蛟河市新站镇和梅河口市海龙镇选择抗性不同的当地主栽品种按不同比例搭配种植,进行了控制稻瘟病试验。结果表明：水稻品种混合间栽可有效控制稻瘟病的发生,控病效果主要体现在感病品种上。对感病品种“吉优1号”的控制效果达95．94％,对“丰优301”的控病效果达57．14％和49．21％,对“超产2号”的控病效果达63．59％。选择抗谱不同的品种搭配种植可取得较好的效果。“松粳6号”与“吉优1号”组合,2个品种的致病菌谱完全不同,对感病品种“吉优1号”的控病效果高达95．94％。

| Abstract: | To control rice blast, major local rice varieties with different resistances were inter-planted in different proportions in Sinzha town of Jiaohe city and Hailong town of Meihekou city in 2002 and 2003. The results showed that the combination of different rice varieties is effective in controlling rice blast. Combined planting to select different pedigree-resistant varieties is more evident to control rice blast.The control effect on rice blast of Jiyou1 was 95.94%, that of Fengyou301 was 57.14% and 49.21% and that of Chaochan2 was 63.59%. The inter-planting of varieties with different resistance spectrums could reach a better control effect. The combination of Songjing6 and Jiyou1, two varieties with contrastive resistance spectrums, could reach a control effect of 95.94% on rice blast of Jiyou1. |
