平菇是营养丰富、颇受城乡人民喜爱食用的蔬菜,也是一项农民增收致富的重要门路。但在其生产过程中,也会出现一些技术上的问题。笔者从事食用菌生产、推广多年,曾荣获省市科技成果,积累了一定的实践经验。针对目前在平菇栽培出现的第一年成功,第二年受污染,第三年病菌严重的情况,特提出以下关键技术措施:一、严格选料,注意消毒。平菇生料栽倍,必须使用新鲜的无霉培养料,并在使用前必须暴晒三天,利用阳光中紫外线杀死杂菌,拌料时再加入0.2%的多菌灵和3～4%的新鲜生石灰水伴匀。二、掌握好培养料含水量。播种前把培养料湿度调节在60%左右,即每百公斤培养料加水120～125公斤,用 Pleurotus ostreatus is a nutrient-rich vegetable popular with urban and rural residents and an important gateway for farmers to increase their incomes. But in the course of its production, there will be some technical problems. I engaged in mushroom production, promotion for many years, has won provincial and municipal scientific and technological achievements, has accumulated some practical experience. For the current mushroom cultivation in the first year of success, the second year of pollution, the third year of serious germs, especially the following key technical measures: First, the strict selection of materials, pay attention to disinfection. Pleurotus ostreatus times, you must use fresh mold-free culture material, and must be exposed to three days before use, the use of ultraviolet rays to kill bacteria in the sun, spices and then add 0.2% carbendazim and 3 to 4% Fresh lime water with even. Second, master training material moisture content. Before planting, the humidity of the culture material is adjusted to about 60%, that is, 120 to 125 kg of water per 100 kg of culture material,
