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。
Fusarium solani, Alternaria tenuis and Rhizoctonia solani, which caused the seedling blight of Pinus sylvestris, were tested with different soil nurseries and 7 fungicides. The results showed that the incidence rates of different soils were 5.1% for mixed soil, 13.1% for humified soil, 34.2% for topsoil and 36.8% for disinfected soil. Pharmacodynamic determination of ferrous sulfate, copper sulfate on three kinds of bacteria have an inhibitory effect. Copper sulfate has a killing effect on Fusarium and Rhizoctonia, while it inhibits Alternaria.
