1、播种后菌丝不萌发、不吃料,只在料面生长及出现萎缩现象。是由于菇房内的温度、通风情况及湿度不当等原因造成的。若培养料表面偏干,可及时喷过磷酸钙或磷酸二氢钾水溶液;如料过湿则要加强菇房通风;当菇房内气温较高时要采取降温措施,使其达到适宜的温度范围;当菇房内有氨臭味时,要及时加大通风量,在培养料面戳洞,排除氢气。 2、覆土后菌丝体徒长。播种后营养生长过旺,绒毛状菌丝生长致密,覆土后常冒出土面,形成不透水、不透气的“菌被”层。主要是由于高温、高湿环境导致菌丝体徒长。防止菌丝“结被”的措施是当菌丝长出覆土层时,加强菇房内通风,降低菇房内温度和空气湿度,并及时喷“结菇水”,以利原基的形成。喷水不要太急,要在早晚凉爽时喷水。一
1, mycelium does not germinate after sowing, do not eat material, only the material growth and shrinkage phenomenon. Is due to mushroom house temperature, ventilation and humidity caused by improper and other reasons. If the training material surface is dry, can be sprayed with calcium phosphate or potassium dihydrogen phosphate solution; if the material is too wet, mushroom house ventilation should be strengthened; when the mushroom house temperature is higher, cooling measures should be taken to reach the appropriate temperature Range; when the mushroom house smell of ammonia odor, it is necessary to increase ventilation in time, poking hole in the training material, excluding hydrogen. 2, after the soil mycelical legwork. Vegetative growth after sowing, dense growth of villous mycelium, soil often emerge from the soil surface, the formation of impermeable, impermeable “bacteria is” layer. Mainly due to high temperature, high humidity environment mycelium leggy. Prevention of mycelium “knot was” measures is when the mycelium grow overburden, strengthen mushroom house ventilation, reduce mushroom house temperature and air humidity, and timely spraying “mushroom water” to facilitate the formation of primordia. Do not spray water too quickly, to spray water sooner or later cool. one
