| 摘 要： | 分析了调整播种期前后豫南粳稻生育期内的气候特点与水稻稻瘟病、纹枯病发生流行适宜气候条件对应关系的变化,指出豫南粳稻按常规方式种植,稻瘟病、纹枯病易大发生的原因在于其孕穗灌浆期处于高温高湿时期,推迟播种期后,孕穗灌浆期避过高温高湿时期,稻瘟病和纹枯病发生轻甚至不发病,解决了豫南粳稻病害重的难题。

| Abstract: | Analysed the change between climate characteristic of Japonice Hybrid Rice growth stage and homologous climate condition of Rice Blast and Sheath Bligh diseased before and after adjust seeding time in south henan. Enucleated the reason of Rice Blast and Sheath Bligh diseased easy is the heading time of Japonice Hybrid Rice in high temperature and high humidity period general. After adjust seeding time, heading time escape from high temperature and high humidity period, Rice Blast and Sheath Bligh little diseased even none, answered the problem of Japonice Hybrid Rice diseased heavy in south Henan |
