The fied experiment was conducted to explore the effects of different varieties,different exogenous nutritious bags and different placement times on the production traits of Morchella.The results showed that among the 7 tested varieties,MH1 mycelium grew vigorously and yielded the most,with the output of 3 195 kg per hectare.Among the 9 different exogenous nu-tritious bags,formula V and I showed strong mycelial growth and higher yield,with the output of 2 685 kg per hectare and 2 235 kg per hectare,respectively.Among the 5 different nutritious bag placement times,15 days after sowing was more suitable,with the output of 1 785 kg per hectare.
