【摘要】 采用不同土壤育苗和７ 种杀菌剂室内药效测定技术，对引起松苗立枯病的病原腐皮镰刀菌（ Ｆｕｓａｒｉｕｍ ｓｏｌａｎｉ）、细交链孢菌（ Ａｌｔｅｒｎａｒｉａ ｔｅｎｕｉｓ）和立枯丝核菌（ Ｒｈｉｚｏｃｔｏｎｉａｓｏｌａｎｉ）进行了防治试验，结果表明：不同土壤发病率为混合土５．１％ ，腐殖质土１３．１％ 、表土３４．２％ 、消毒土３６．８％ 。药效测定结果为硫酸亚铁、硫酸铜对３ 种菌均起抑制作用。硫酸铜对镰刀菌和丝核菌具有杀死作用，而对交链孢菌起抑制作用。更多还原

【Abstract】 Control trial on 3 kinds of fungi (Fusarium solani, Alternaria tenuis and Rhizoctonia solani) responsible for seedling blight of Pinus was carried out by measuring the control reval effects of 7 fungicides in various soils indoors. The results showed that incidence of the disease was 5.1% in mixture soil, 13.1% in humus soil, 34.2% in surface soil and 36.8% in disinfected soil. Copper sulfate could kill Fusarium solani and Rhizoctonia solani, restrain Alternaria tenuis, but ferrous sulfate could only restrain them.更多还原
