Abstract: Based on the multip le fungi biopulp ing technology, the wood basic density (WBD) , fibre form and chemical components of 10 pop lar clones were used to study the biopulp ing feasibility of pop lar minirotation copp iceshoot. The result showed that the wood quality characteristics of 1 and 2 years－old pop lar could fulfill the technicalrequirement of pulp ing and papermaking. Copp ice shoots can be used to biopulp ing. The pulp yield of biopulp ingwas between 65. 0% and 72. 0%, and the quality of pulp was up to the par of state standard Bk－C level of broadleave wood pulp. The differences of wood quality characteristics are so significant among clones that it is much important to select a fast－growing, good quality ofwood and well adap ted clone of populuswhen establishing the minirotation pop lar pulp stand.
