茶苗根结线虫病茶苗根结线虫病tea seedling diseases caused by root-knot nematodes茶苗根结线虫病(tea seedling diseaseseaused by root一knot nematodes)茶苗根部寄生性线虫病害之一。分布于浙江、安徽、台湾、福建、广东、广西、四川、云南等省区;斯里兰卡、印度、日本和非洲等产茶国均有发生。此外还为害瓜、豆、薯、麻、烟、桑、果等植物。症状由于线虫分泌物的刺激，使虫体附近根组织形成巨型细胞，并促使根细胞过度分裂，导致受害部位崎形或形成大小不等的澳瘤，须根少发或不发，根功能衰退，植株矮小，叶黄，严重时大量落叶以至死亡。茶苗根结线虫病病原主要为南方根结线虫，学名为材￡loid之吸少之e- 州‘口g”i匆(Kofoid and White head)Chitwood，其次为爪哇根结线虫学名为M血va”t’ca(Treub.)Chitwood、花生根结线虫学名为M.arena而(Neal)Chitwood和泰晤士根结线虫学名为M.than奴‘1 Chit.wood，国际上还记载有北方根结线虫学名为M.ht，l-加Chitwood和短体根结线虫学名为M.brevtcaudaLoos，后者除加害茶苗外，还加害成龄茶树。上述各种线虫均属线形动物门、线虫纲垫刃目根结线虫科根结线虫属。一生有卵、幼虫和成虫三个发育时期。雄成虫线形，长宽为1.20一1.50火0.03一0.04毫米;雌成虫柠橄形，头部尖，身体膨大，长宽为0.44一l.30X0.33一0.70毫米，卵产于雌虫尾端的胶质卵囊内。侵染规律以雌成虫和卵在病根虫澳中越冬。1龄幼虫在卵内生活，从卵内孵出的是2龄幼虫，通过土壤或虫姿组织到达新根，从根尖附近侵入，固定寄生。成熟雄虫逸出根组织在土中自由生活，寻找雌虫交配。当环境适宜时，20一30天完成一代。病根残留组织和病土均可通过人为活动作远距离传播。砂质上利于发病，熟地比生地发病重。l一2年生茶苗感病显著，茶树品种间抗病性差异较大。防治必须强调“预防为主、综合防治”的原则。选用无病地育苗或植苗;使用感病地时.约提前两个月在烈日下多次翻晒土坡，杀灭土中线虫;尽量选用适宜当地种植的高产抗病品种:加强肥水管理、增强茶苗抗病能力;控制病苗扩散:有些国家还间作万寿菊抑制线虫种群数量;使用涕灭威、吠喃丹、灭线磷、克线磷等进行化学防治。(喻盛甫)
