通过4年的引种试验，结果表明，黧萌生长快，菇术产量高，生物量大，直播造林4年生单株平均胸径、树高，冠幅和菇木产量分别为3．7cm、4．0cm、25.和5.2kg,分别是乡土速生菇木树种马桂木、枫香、拟赤杨的1．5～2.2倍、1．3～1．5倍、1．3～2、1倍和4．3～87倍；适应性较强，浅极性，幼苗对环境的抗逆性较弱，生长缓慢，第3年开始表现出速生的特性。适宜在我区低山、丘陵地引种推广。 After 4 years of introduction test, the results showed that the average diameter at breast height, tree height, crown width and mushroom yield were 3.7cm and 4cm, respectively. 0cm, 25 and 5.2kg, respectively, native veliger wood tree species Guimai, sweetgum, Alnus want to 1.5 to 2.2 times, 1.3 to 1.5 times, 1.3 to 2,1 times and 4.3 ~ 87 times; Adaptability, shallow polarity, seedling resistance to the environment is weak, slow growth, the first three years showed the characteristics of fast growing. Suitable for low mountains in my area, introduction and promotion of hills.
