试验结果表明：美洲黑杨完全适应景宁的气候条件，具有很强的耐寒性和速生性；培育一般用材林，栽植后 10 年即可主伐；培育菇木林、栽植后 3～4 年即可采伐利用。现有研究结果已表明，美洲黑杨木屑栽培香菇比混合木屑产量高 6.9%，用以种植黑木耳比常规混合木屑产量增加 7.7%。景宁是香菇、黑木耳的主产区，引种推广美州黑杨，并引进美洲黑杨菇、耳超短轮伐期两用林营建技术，开展杨树木屑栽培袋料香菇、木耳最佳基质配比的研究，对于开发菇木、耳木林资源具有重要的意义。

Populus deltoides is completely adapted to the climatic conditions in Jingning, with the characteristics of cold tolerance and rapid growth.The bred general timber forest can be mainly cut after 10 years;the bred mushroom forest can be felled after 3～4 years.The present research showed that, Lentinus edodes cultured with saw dust of Populus deltoides could increase production of and Auricularia auricula 6.9% and 7.7%, respectively,compared with general mixed sawdust. Jingning is the main production area of Lentinus edodes and Auricularia auricula .Therefore, it is significant for development and utilization of mushroom forest and Auricularia auricula forest to introduce to Populus deltoides and popularize management techniques for short-rotation double-utilization forest.
