- 摘要:
- 以大棚连茬茄子为调查对象，采用形态观察法，研究了感染茄子根结线虫的种类及危害。结果表明：3栋大棚茄子根结线虫病发病率达80%，根结指数为17.9；解剖镜下解剖观察根结，发现根结内有大量的雌虫和卵；分离获得雌虫、雄虫和2龄幼虫后分别进行观察和测量，并制作雌虫的会阴花纹切片进行比较鉴定,发现危害茄子的病原线虫为南方根结线虫(Meloidogyne incognita)。
- Abstract:
- Taking continuous cultivation eggplants as investigation objects，using morphology observation method，the species and harm of continuous cultivation eggplant’s root-knot nematode in greenhouse were investigated.The results showed that the incidence of eggplant root-knot nematode disease in 3 greenhouses was 80%，the root knot index was 17.9.There were a large number of females and eggs in the root knot under the microscope.Female，male and 2nd instar larva were isolated，observed and measured.Also perineal-striae was made in order to identify nematode species.The pathogen of eggplant root-knot nematode disease was Meloidogyne incognita.
