杂糯间栽技术控制稻瘟病试验

目的]研究栽培技术对稻瘟病的发生与为害的控制作用,为稻瘟病的大田防治提供参考。方法]试验设5个处理,分别为4+1、6+1、8+2、杂稻净作和糯稻净作。其中,4+1、6+1、8+2处理为:每隔2个宽行栽1行糯稻,每隔3个宽行栽1行糯稻,每隔4个宽行栽2行糯稻。结果]结果表明:杂稻与高感糯稻间栽,4+1、6+1、8+2处理对杂稻叶瘟、穗颈瘟的控制效果不明显,但4+1、6+1处理对高感糯稻叶瘟控制效果较好,8+2处理控制效果较差;4+1、6+1、8+2处理对高感糯稻穗颈瘟的控制效果都较好,其穗颈瘟的发生明显低于糯稻净作。结论]杂糯间栽技术对糯稻栽培在生产中叶稻和穗颈瘟的发生与为害均有控制作用。

Test of Using Intercrop Hybrid and Glutinous Rice Technology Controlling Rice Blast

Objective] The research aimed to study the action of cultivate technique to control rice blast,providing reference for cure rice disease in field.Method] The test designed 5 treatments,including 4 1,6 1,8 2,hybrid rice simple plant and glutinous rice simple plant respectively.Thereinto,4 1,6 1,8 2 treatments were planting 1 row glutinous rice every 2 width rows,planting 1 row glutinous rice every 3 width rows,planting 2 row glutinous rice every 4 width rows.Result] The result showed that 4 1,6 1 and 8 2 treatments had no obvious action on the leaf and spice neck disease of hybrid rice,but 4 1 and 6 1 treatments had obvious action on the leaf disease of glutinous rice.4 1,6 1 and 8 2 treatments all had obvious action on the spice neck disease of glutinous rice.Conclusion] The technique of intercrop hybrid and glutinous rice can control leaf and spice neck disease of glutinous rice.
