Abstract：This experiment was conducted under saline-alkali conditions to study the effects of adding Tremella fuciformis residue in saline-alkali soil with volume ratios of 0,10.0%,20.0%,30.0%and 40.0%on growth and quality of Morchella spp..The results indicated that adding T.fuciformis residue could significantly decrease the electrical conductivity(EC)and pH values of saline-alkali soil,and increse the moisture,organ-ic carbon,total nitrogen contents of saline-alkali soil.Adding T.fuciformis residue in saline-alkali soil could increase growth rate and speed of obtaining nutrients of Morchella spp.mycelium,increase the cap length,stipe length,cap diameter,stipe diameter,single fresh weight,single dry weight,and yield of fruiting bodies,and the effect was the most obvious when the adding ratio of residue was 30.0%,which were 13.3%,8.8%,13.0%,14.2%,26.3%,26.8%and 38.6%higher than those of the control(saline-alkali soil).Fur-thermore,adding T.fuciformis residue could increase the contents of crude protein,crude fat,total amino acid,crude fiber,crude polysaccharide and ash in fruiting bodies.The contents of crude protein,crude fat and total amino acid reached the highest value when the adding ratio of residue was 20.0%,which were 20.2%,26.1%and 19.8%higher than those of the control;the contents of crude fiber,crude polysaccharide and ash reached the highest value when the adding ratio of residue was 30.0%,which were 40.1%,27.7%and 25.3%higher than those of the control.Therefore,under the conditions of this experiment,adding 20.0%to 30.0%of T.fuciformis residue could promote the growth and development of Morchella spp.in saline-alkali soil,and thus improve its yield and quality.
