南方根结线虫的天敌真菌

 试用直接解剖法,贝曼漏斗法,直接分离法,差速离心法,贝曼漏斗法+(Drechsler法和直接分离法+Drechsler法从浙江省金华棉花和杭州市的黄杨根围土中分离到9种寄生南方根结线虫的真菌:Verticilliuminsectorum,V.cephalosporium,V.sp.,Harposporium anguillulae,H.oxysporium,Monacro-sporium eudermata,M.cystoporum,M.fusiformis和Nematoctonus pachysporus.6种分离方法中以直接解剖法和差速离心法效果较好.

THE MYCOFLORA OF COTTON ROOT-KNOT NEMATODE (MELOIDOGYNE INCOGNITA)

Direct dissection method,Baermann funnel technique,Direct isolation procedure,Differential centrifugation method,Baermann funnel technique+ Drechsler's method and Direct isolation procedure+Drechsler's method were tested to isolate the nematodedestroying fungi of M.incognita.From the cotton rhizosphere at Jinhua and Buxus sinica rhizosphere at Hangzhou in Zheiiang Province,nine fungi parasitic on M,incognita were isolated,i.e.Verticillium insectorum,V.cephalosporium,V.sp.,Monacrosporium endermata,M.cystoporium,M.fusiformis,Harposporium anguillulae,H.oxysporum and Nematoctonus Pachysporus,Direct dissection method and Diffrential centrifugation technique have been proved to be more effective than the other four procedures tested.
