牡丹江地区杨树短轮伐期条材经营模式的研究

Studies on the Management Model of Short Rotation Poplar Timber in Mudanjiang Region

采用渤丰3号杨和177杨,并将扦插密度提高到13.3万株/hm^(2),培育杨树1年生条材,可以将单位面积生物量产出从迎春5号杨现行育苗方式的5.09 t/hm^(2),分别提高到15.43 t/hm^(2)和15.6 t/hm^(2),效益显著。试验数据初步论证了牡丹江地区采用短轮伐期经营模式培育杨树条材的可行性。

Using Bofeng No.3 poplar and 177 poplar,and increasing the cutting density to 133000 plants/ha to cultivate annual poplar cuttings can increase the biomass output per unit area from 5.09 tons/ha of the current row seedling cultivation method of Yingchun No.5 poplar to 15.43 tons/ha and 15.6 tons/ha respectively,with significant benefits.The experimental data preliminarily demonstrated the feasibility of using a short rotation period management model to cultivate poplar timber in the Mudanjiang area.
