Total demand is down to village, household, persons, County, town, and village books, card 防治要坚持“预防为主,综合防治”的原则。 ?水稻稻瘟病防治 可分为苗瘟、叶瘟、穗颈瘟等,危害水稻各部位。水稻整个生育期都有发生,病斑主要有两种:一是急性型病斑,病发时,病斑呈暗绿色,多数近圆形或椭圆形,斑上密生青灰霉层;二是慢性型病斑,病斑为梭形,或长梭形,外围有黄色晕圈,内部为褐色,中心灰白色,有褐色坏色线贯穿病斑并向两头延伸,这是本病的一个重要特征,穗颈瘟常在穗下第一节穗颈上发生淡褐色或绿色的变色部分,影响结实,形成白穗、枯穗;分枝或小枝也可发病,影响病枝结实,又称“枝梗瘟”。 主要预防措施: ?按水稻需肥规律,采用配方施肥技术,后期做到干湿交替,促进稻叶老熟,增强抗病力。 ?施药适期:秧田在发病初用药;本田分蘖开始,每3天调查一次,主要查看植株上部3片叶,如发现发病中心或叶上急性病斑,即应施药防治;预防穗瘟,根据病情预报,多肥田为对象,掌握破口期,个别抽穗,时打药。 ?施药类型和剂量:抓住关键时期,适时用药。早抓叶瘟,狠治穗瘟。发病初 期每亩用2%春蕾霉素50克杜邦万兴水剂30克,加水50,60公斤喷雾。叶瘟要连防2,3次,穗瘟要着重在抽穗期进行保护,特别是在孕穗期,破肚期,和齐穗期是防治适期。 ?水稻稻曲病的防治 水稻稻曲病又名谷黄,又称伪黑穗病、绿黑穗病、谷花病、青粉病,俗称“丰产果”。该病只发生于穗部,危害部分谷粒。受害谷粒内形成菌丝块渐膨大,内外颖裂开,露出淡黄色块状物,即孢子座,后包于内外颖两侧,呈黑绿色,初外包一层薄膜,后破裂,散生墨绿色粉末,即病菌的厚垣孢子,有的两侧生黑色扁平菌核,风吹雨打易脱落。全国各稻区均有发生。在八十年代之前,该病为零星发生,熟次要病害。九十年代以来,由于密粒直立型高产水稻品种的大面积推广,单季稻熟制的扩大,施肥水平偏高和不合理,尤其是单季稻孕穗期至抽穗期多雨适温的频率较高,致使稻曲病的发生面积逐年增加,为害日益加重,已成为我省水稻的主要病害。 planning, and government financing, and whole village relocation, and first built Hou split" of principles, insisted big community planning, and large district transformation, break administrative divisions boundaries, optimization town spatial structure, speed up new Community construction, formed new community live building, and intensive with ground project, and enterprise tax insurance running, and Expand employment and improve people's livelihood shed changed economic chain.
