许多腐生型线虫,有时还有食菌线虫,Aphelenchoides composticola都寄生于泥炭中,而托拉氏假单孢杆菌(Pseudomonas tulaasii)——蘑菇细菌性斑腐病的病原菌,也经常污染泥炭藓。在堆制培养料对,用克线磷(Fenamiphos)—乙基—3—甲基—4—(甲基硫代)苯基(1—甲基乙基)磷酰胺(C_(13)H_(22)NO_3P_5)可以消灭A.composticola,但防止蘑菇细菌性斑点病病原菌孳生,目前尚无有效的方法。环氧乙烷(ETO_2,CH_2CH_2O)具有杀菌作用,可以穿透常用来包装泥炭的聚丙烯塑料袋,熏蒸过的物质,没有农药残留问题,因而可考虑用作杀菌剂。本试验就是测定环氧乙烷对蘑菇覆土泥炭藓中线虫和斑点病菌的杀灭效果。
Many saprophytic nematodes, and sometimes nematophagous nematodes, are parasitic on the peat, and Pseudomonas tulaasii - the pathogen of the mushroom bacterial spot, often pollutes the peat moss. In the compost culture pair, Fenamiphos-ethyl-3-methyl-4- (methylthio) phenyl (1-methylethyl) phosphoramide 22) NO_3P_5) can eliminate A.composticola, but to prevent the mushroom bacterial speck pathogen breeding, there is no effective method. Ethylene oxide (ETO_2, CH_2CH_2O) has a bactericidal effect and can be used as a bactericide to penetrate through the polypropylene plastic bags commonly used for packaging peat, fumigated substances, and have no pesticide residue. This test is to determine the impact of ethylene oxide on nematodes and speckles in mushroom-coated peat moss.
