摘要
以不同剪枝方法对欧美107速生杨立木蓄积量的影响进行了研究。结果表明:不同的剪枝方法呈显著差异;三年一根棍的剪法,5 a生树有效立木蓄积量已达到14.75 m3/667m2,与养干法相比高1.30 m3,与传统法相比高4.48 m3,养干法与传统法相比高3.18 m3;其简易的计算方法可采用国标杉木原条材积表。
Impact of different priming methods on stumpage amount of Europe and the United States poplar 107 was studied. The results showed that different pnming methods affected significantly on the amount of growing stock： for the method of a stick cut in three years, the five- year-old trees effective growing stock volume reached 14.75 m^3/667m^2 ,and 1.30 m^3 higher than the method of mink maintenance, and 4.48 m^3 higher compared with the traditional method, while the method of tnmk maintenance had a volume of 3.18 m^3 higher compared with the traditional method. The GB fir volume table for original bole can be used as its simple method of calculation.
