从土壤和病株上分离到10个线虫的天敌真菌菌株,其中有三个菌株较有希望,烛台霉属(Candelabrello sp.)一个。孤孢属(Monacrosporium spp.)两个,菌株代号分别为CN_7;CN_(?)和CN_5。 据试验:CN_7较好,菌丝体生长的温度范围是20～33℃,最适宜的温度范围是25～30℃,以式捕捉环捕食线虫,对培养基选择性不强,最适宜的pH值是6.0～7.5,但在pH4.5～8.0都能进收缩行捕捉,捕捉器官形成量多,捕虫势强且稳定,在水中也能形成捕捉环并捕食线虫。
Ten nematode fungal isolates were isolated from soil and diseased plants, of which three were more promising, one from Candelabrello sp. Two Monacrosporium spp. Strains were identified as CN_7, CN_ (?) And CN_5 respectively. According to the test: CN_7 is better, the mycelium growth temperature range is 20 ~ 33 ℃, the most suitable temperature range is 25 ~ 30 ℃, to catch the ring predation nematode, the medium selectivity is not strong, the most appropriate pH The value is 6.0 ~ 7.5, but at pH4.5 ~ 8.0 can shrink into the capture, capture the formation of organs, insect strong and stable, can form a capture loop in water and predation nematodes.
