秋蘑菇经过1个多月的发菌培养,菇床内害虫和病菌基数较大,尤其是螨虫、跳虫、菇蚊和有害疣孢霉等病虫对秋蘑菇造成较大危害。发菌过程中发现菌丝有退菌现象,如绒毛状菌丝减少,索状菌丝增多,菌丝表层有粉红状粉层或有白色发亮点,用放大镜观察见有螨虫缓慢移动,表明有螨虫危害。如果放大镜下所看到的范围内有3—5只螨虫,即需防治。覆土后螨虫多集中于原基和菇柄基部取食,造成根部光秃,无菌根,蘑菇因营养无法输送而萎缩死亡。
Autumn mushrooms after more than a month of germ culture, mushroom bed pests and bacteria in a larger base, especially mites, hoppers, mushroom mosquitoes and harmful mulberry mold caused greater harm to autumn mushrooms. Hair removal process found mycelium with the phenomenon of withdrawal, such as reduced villous mycelium, cord-like mycelium increased, mycelial pink powder layer or white hair highlights, with a magnifying glass to see the slow movement of mites, indicating that there is Mites harm. If the scope of the magnifier to see 3-5 mites, that is to be controlled. After the soil mites and more concentrated in the base and mushroom handle base feeding, resulting in bare roots, sterile roots, mushrooms due to nutritional inability to transport and shrinking death.
