| 摘 要： | 近年来水稻纹枯病在江西南部地区发生普遍而严重,已成为水稻丰产的障碍。株间光照弱,温度高,通风不良,相对湿度高会促进病害的严重发生。在农业栽培措施中,肥料,尤其是氮素肥料对发病影响最大,氮肥愈多病害愈重,肥料配合与施用方法和插秧密度也影响病害的发生,分蘖后浅水灌溉,发病较轻,合理落水晒田可抑制病势发展,不当的栽培技术引起水稻倒伏,会促进病害剧烈发展,而病害的加重又促进植株倒伏。水稻感病程度的轻重依次为粳、籼、糯。粳稻一般发病较重。品种间抗性差异极大,但尚未见免疫品种。同一品种不同品系也有差异,经过选育的新品系,抗病程度有一定增强。在防治上,捞除田间菌核有一定防病作用。插秧前,利用药剂消毒、稻田淹水层,防病增产效果较大,其中茶籽饼液药效最好,田间防治效果71.5—95.8%,增产稻谷6.8—47.3%。消毒早稻田后,对晚稻防病增产仍有残效。

| Abstract: | In recent years,the Rhizoctonia blight of rice in southern part of Kiangsi province has assumed an epidemic scale.The disease was found to be encouraged by close planting and high nitrogen fertilization.In general,semi-glutinous rice varieties were more susceptible than non-glutinous and glutinous.There were also varietal difference in susceptibility within each group.Effectiveness of sweeping out the sclerotia off the flooded fields before planting and apply-ing fungicidal materials on flooded fields before planting and on growing plants in disease control were studied.Application of 1,500 kg.per hector of tea seed cake before planting appeared to be promising. |
