CTP-5对食用菌种植基质的消毒种植试验

试验选取CTP-5和多菌灵两种消毒剂,设计了0²0 000 mg/L 7种浓度梯度组,对食用菌培养料进行处理后接种平菇菌种进行培养,通过观察食用菌菌丝的生长情况以及杂菌的生长情况,以研究CTP-5消毒灭菌效果。结果表明:CTP-5和多菌灵两种药剂处理培养料都具有明显的防污染效果,CTP-5和多菌灵的有效消毒灭菌浓度分别是10 000 mg/L、8 000 mg/L。但药物处理组与高温灭菌组对照比较,其菌丝生长较慢,CTP-5与多菌灵处理组比较,消毒效果和菌丝生长差异不明显。CTP-5是无毒\无残留的新型消毒剂,可代替多菌灵在食用菌培养料中进行辅助消毒,防治污染。

Planting Experiments of CTP-5 Disinfection to Mushroom Growing Substrate

Chooses two disinfectant,CTP-5 and carbendazim designs seven concentration gra-dient between 0~20 000 mg/L,after mushroom culture material handling,Inoculates mush-room strains and cultures. Researches the sterilizing effect of CTP-5 by observing the growth of mush-room mycelium and the growth of bacteria. The results show that CTP-5 and carbendazim both have obvious disinfection effect to mushroom culture material,the valid disinfection concentration of CTP-5 and carbendazim are respectively 10 000 mg/L and 8 000 mg/L. compared with high temper-ature sterilization group,the growth of mushroom mycelium is slower in medicone group. Compared with carbendazim group,the difference of disinfection effect and mycelium growth is not obvious in CTP-5 group. CTP-5 is a kind of new disinfectant which is innoxious and noresidue,can substitute for carbendazim to complementary disinfection and pollution prevention in mushroom culture materi-al.
