摘要：

本试验采用抗稻瘟病性不同的3个品种为材料，研究了品种混植对寒地稻瘟病流行的防治效果以及对产量、品质的影响。结果表明，在寒地早粳稻作区，利用抗病品种跟感病品种混植可以有效抑制叶瘟、穗颈瘟的发生，随着抗病品种比例的提高，发病率明显下降。不同品种组合抑制稻瘟病效果为-11.5%～-63.2%。品种混植后增加了产量，增产幅度1.5%～12.0%，外观品质和食味品质略有提高。

Abstract:

With three rice varieties of different resistance to rice blast as the materials, study on mixture inter-planting of different rice varieties to control rice blast and effects on yield and quality of rice in cold region. The results showed that leaf blast and panicle-neck blast could be effectively suppressed under the condition of mixture inter-planting of different resistance to rice varieties in cold region. With the increase in the proportion of resistant rice varieties, the incidence of blast has decreased significantly. The inhibitory effect of different treatments on rice blast was -11.5%～-63.2%. Yields were increased by 1.5%～12.0% after mixture inter-planting of different resistance to rice varieties, and the appearance quality and cooking quality were increased slightly.
