冷冻法防治蘑菇害螨的初步探讨

PRIMARY STUDY ON THE METHOD OF CONTROLLING MUSHROOM MITE WITH FROZEN CULTURAL SPAWN

蓝氏布伦螨Brennandania lambi(Kaczal)是上海蘑菇的主要害螨。主要侵染源是染有该害螨的蘑菇栽培种。将此类菌种置冷库中于-10℃处理24h,杀螨效果理想。实验室和郊区菇床实地应用结果表明,以-10℃处理过的菌种栽培,蘑菇生长正常,其产量和无害螨对照一致。

The mite, Brennandania lambi(Krczal )is the most harmful one of mushroom. The infection source of this mite is the cultural spawn contaminated by this mite primarily.It is satisfactory that this mite can be killed at the temperature —10℃ lasting 24 hours. The spawn treated by this condition is cultured in laboratory and mushroom begs in suburbs, there is no damage in mushroom beds cuased by B. lambi. The mushroom growth is normal and the yidel is consistent with the contrast.
