摘要
通过持续６年，面积达２３．６７ｈｍ￣２的造林试验，初步探索出适于云南引种区采用的马尖相思育苗、造林技术。在普文引种试区马尖相思生长迅速，６年生树高年均生长量达２．３１ｍ，胸径年均生长量为２．９ｃｍ，活立木蓄积２８９．０４１４５ｍ￣３／ｈｍ￣２，年均生长量４８．１７３５７５ｍ￣３／ｈｍ￣２；４．５年生的马尖相思林，地上部分生物量达１０５．６ｔ／ｈｍ￣２，有较高的经济和生态效益。
The planting experiment has been done through 6 years,the experiment area isabout 23.67hm2,and the techques for growing seedIing and planting of Acacia mangium hasbeen found in the introduction test place,Acacia mangium grows very fast,the tree height is2.31m in 6 years old,the tree diameter is 2.9cm,the volume─increment of living tree is289.04145m3/hm2,the growth increment is 48.173575m3/hm2.The trees of 4 and half yearsbiomass yleld of above growth is 105.6t/ hm2,and the economic and ecological effieency isvery signifieent.
