摘　　要：为筛选出符合当地农业生产实际和饮食习俗的防治稻瘟病的杂糯间栽种植组合,采用3个水稻主栽品种分别与1个优质感病糯稻品种按6∶1和4∶1的比例搭配种植进行试验。结果表明,两种间栽模式均能有效降低优质高感糯稻品种稻瘟病的发病率,平均防效达88%,平均增加产量32.17 kg/667m2。经田间防效和产量对比分析,"6+1"间栽模式更适合于当地的水稻栽培模式。可作为雷山县稻瘟病综合防治的措施推广应用。Field experiments for 4 rice varieties,which include 3 hybrid varieties and 1 glutinous variety,were conducted based on 2 intercropping proportions 6∶1 and 4∶1 in Leishan Country in order to screen intercropping combinations of hybrid rice and glutinous rice.The result showed that both the two intercropping combinations could reduce the occurrence of rice blast for the high quality and highly susceptible glutinous variety.The average control efficiency on panicle blast was 88% with the average yield increased 32.17 kg/667m2 '6+1' combination was more suitable for native rice cultivation mode in Leishan County based on the comparison analysis of field control efficiency and yield,and could be implemented as one of integrated control measures for rice blast.
