采用修正的琼脂玻皿法研究了四种杀虫杀螨剂对草菇菌丝生长的影响.结果表明,不同药剂对草菇菌丝生长的影响程度存在着显著差异.其中敌敌畏对草菇菌丝生长的影响最大,其平均抑制率为-65.55%;中西溴氟菊酯影响最小,平均抑制率为-11.40%,且在25.00×10~(-6)和20.00×10~(-6)的低浓度下对草菇菌丝的生长还有促进作用,促进率分别为+11.25%和+17.75%;灭螨灵和氯氰菊酯的平均抑制率分别为-29.20%和-29.60%.药剂的浓度与草菇菌丝的生长率成显著或极显著的负相关,即草菇菌丝的生长率随药剂处理浓度的增大而降低.本研究结果还表明,药剂对草菇菌丝生长的影响不仅表现在生长率上,还表现在草菇菌丝密度、分枝次数、厚垣孢子数量及菌丝色泽上.
The effects of four insecticides and acaricides on mycelium growth of mushroom were studied by modified agar glass dish method.The results showed that there was a significant difference in the influence degree of different medicaments on mycelium growth of mushroom The average inhibitory rate was -65.55%. Bromoflumene had the least effect with the average inhibition rate of -11.40%, and the average inhibitory rate was 25.00 × 10 -6 and 20.00 × 10 -6, Of the low concentration of mushroom mycelium growth also promote the promotion rate were +11 .75% and 17.75%; mites and cypermethrin the average inhibition rates were -29.20% and -29.60%. The concentration of the drug The growth rate of mushroom mycelium was a significant or very significant negative correlation, that is, the growth rate of mushroom mycelium decreased with the increase of the concentration of the drug treatment.The results also showed that the effect of the agent on the growth of mushroom mushroom mycelium Not only reflected in the growth rate, but also in the mushroom mycelium density, branching frequency, chlamydospore number and mycelium color.
