一是温差刺激法 对菌床采用白天盖膜升温,傍晚或早晨揭膜降温。菌丝生长期相对湿度控制在70％以下,后期保持在85％～90％。这些措施有利于菇耳的形成。 二是药物刺激法 配制培养料时,适当加入磷酸二氢钾、过磷酸钙、维生素B_1等,有明显的增产效果。在菌丝生长后期,用0.1～0.2毫克/升三十烷醇喷于培养料面上,可促进生长、出菇,可增产 10％～15％。
First, the temperature difference between the law of bacteria used to cover the daytime cover film warming, exposing film in the evening or morning cooling. Mycelial growth phase relative humidity control below 70%, late to maintain at 85% to 90%. These measures are conducive to the formation of mushroom ears. Second, when the drug-stimulating method is used to prepare the culture material, proper addition of potassium dihydrogen phosphate, superphosphate, vitamin B_1 and the like can obviously increase the yield. In the late mycelium growth, with 0.1 ~ 0.2 mg / l triacontanol sprayed on the culture material surface, can promote growth, fruiting, can increase 10% to 15%.
