采用改良琼脂玻皿法研究了5种杀虫剂和杀螨剂对蘑菇菌丝生长的影响.结果表明,不同药剂对蘑菇菌丝生长的影响程度差异显著.其中敌敌畏和洗衣粉对蘑菇菌丝生长的影响最大,其平均抑制率分别为-88.64%和-56.77%,两者差异不显著.中西溴氟菊酯和氯氰菊酯次之,平均抑制率分别为-21.52%和-27.89%,两者差异不显著.灭螨灵平均抑制率最小,为-17.04%;药剂质量分数与蘑菇菌丝的生长速度有显著或极显著的负相关,即蘑菇菌丝的生长速率随药剂处理质量分数的降低而加快,中西溴氟菊酯在低质量分数25×10~(-6)和20×10~(-6)时,氯氰菊酯在20×10~(-6)时对蘑菇菌丝有促进生长的作用,其促进率分别为+2.2%、+25.80%、+12.00%.本研究的结果还表明,化学农药对蘑菇菌丝生长的影响不仅表现在生长速率上,而且还表现在对菌丝的密度、粗细及色泽的影响上.
The effects of five kinds of insecticides and acaricides on the mycelial growth of mushroom were studied by modified agar glass dish method.The results showed that the effects of different agents on the mycelial growth of mushroom were significant.The effects of dichlorvos and washing powder on mushroom mycelium The average inhibitory rates were -88.64% and -56.77%, respectively, with no significant difference between the two. The median inhibitory rates of midfloxacin and cypermethrin were -21.52% and -27.89% respectively, both The difference was not significant.The average inhibitory rate of mites mites was -17.04%, and there was a significant or extremely significant negative correlation between the drug mass fraction and the growth rate of mushroom hyphae, that is, the growth rate of mushroom hyphae decreased with the mass fraction However, when chlorpromazuril was applied at low concentration of 25 × 10 -6 and 20 × 10 -6, the growth of mushroom mycelia was promoted at 20 × 10 -6. The results showed that the effects of chemical pesticides on the growth of mushroom mycelium not only in the growth rate, but also in the mycelium Density, thickness and color on the impact.
