金针菇子实体生长期的水分管理是高产优质的关键。近年来,我们摸索出“保、降、促、补、浸”的水分管理方法,取得了很好的效果。现分述如下: (一)保菌丝发到袋底后,表面见吐黄水,立即开袋搔菌,扒去老菌皮,盖湿报纸或塑料薄膜保湿催蕾。覆盖湿报纸的喷水应少量多次(每天3～4次),以保持报纸湿润为宜;覆盖塑料薄膜的,可向地面、空间和墙壁上喷水,保持空气湿度在90％左右。为了保证菇蕾正常发生,此期每天开窗通风30分钟,室温控制在10 Flammulina velutipes fruiting body growth of water management is the key to high yield and quality. In recent years, we have explored the water management methods of “keeping, lowering, promoting, supplementing and dipping” and achieved good results. Now described as follows: (a) Paul germs sent to the bottom of the bag, the surface see spit yellow water, immediately bag scratch bacteria, Pa to the old skin, cover wet newspaper or plastic film moisturizing Lei. Cover the wet newspaper should be sprayed a small number of times (3 to 4 times a day), in order to keep the newspaper moist is appropriate; covered plastic film, spray to the ground, space and walls to maintain air humidity at 90%. In order to ensure the normal occurrence of Gulei Lei, this period window ventilation 30 minutes a day, room temperature control at 10
