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。现有研究结果己表明，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。
The results showed that Populus alba was completely adapted to the climatic conditions of Jingning and had strong cold resistance and fast growth. The common timber forest was planted for 10 years after planting, and the mushrooms were cultivated. After 3 to 4 years of planting, use. Existing research has shown that the production of black poplar wood sawdust is 6.9% higher than that of mixed sawdust cultivars, with a 7.7% increase in the production of black fungus compared to conventional mixed sawdust. Jingning is the main producing area of mushrooms and black fungus. Introducing Populus deltoides Populus and introducing Populus euphratica and Auriculata auriculae cultivation techniques to poplar sawdust cultivation bag mushrooms, fungus best The research of matrix proportioning is of great significance for the development of mushroom wood and ear wood resources.
