茶薪菇、杏鲍菇和阿魏蘑是我市近几年开发的珍稀食用菌。目前,除茶薪菇可春、秋季栽培外,杏鲍菇和阿魏蘑都在8～9月份接种生产。由于这时气温较高,再加农民生产设施简陋,特别是在人工日生产量较大和拌料、装袋到灭菌时间抓不紧的情况下,易使培养料酸化。造成制袋大面积污染。一般污染率都在20%以上,高的达30%～50%,生产损失极大。有的农民为了减少制袋污染率,在配料中少配麦皮和不配蔗糖靠减少培养基 Agrocybe, Pleurotus eryngii and Pleurotus is the city developed in recent years rare edible mushrooms. At present, in addition to the tea mushroom can be spring, autumn cultivation, the Pleurotus eryngii and ferulic mushrooms were vaccinated in August to September production. As this time the temperature is high, coupled with poor peasant production facilities, especially in the artificial production of large and spices, bagging to the sterilization time is not tight grasp, easy to acidify the culture material. Cause bag large area pollution. General pollution rates are above 20%, high up to 30% to 50%, great loss of production. Some farmers in order to reduce the bagging contamination rate, less ingredients in the mix of wheat crackers and deserve less by reducing the medium
