摘要：Seven media amended with 30% to 75% (by volume) of spent mushroom compost (SMC) were trialedon two oak tree species to evaluate the possibility of using SMC for oak tree container seedlingproduction by comparing the physical and chemical properties of media and assessing the plantgrowth of oak seedlings. The high electrical conductivity and pH of media amended with SMC decreasedquickly by leaching. Seedling quality index of Quercus aliena decreased as the proportion of SMCincreased in the media. Only the media with 50% or less SMC yielded seedlings similar to or better thanthe control. However, for Q. virginiana, all media except that without perlite gave similar or betterquality seedlings than the control. Nitrogen, phosphorus and potassium contents of shoot weresignificantly increased in both species grown on SMC amended media, except the nitrogen of Q.virginiana. No visual symptoms of nutrient deficiency or toxicity were observed. In conclusion, incontainer seedling production, SMC can be used with perlite as a peat substitute up to 75% for the salttolerant Q. virginiana, and 50% for Q. aliena.
