These trees have been utilized historically for industrial products such as pallets and pulpwood 利用这些树木来生产托盘和造纸已经有多年历史。

A study on management model system and optimum cultivation patterns of pinus massoniana for pulpwood stand 马尾松纸浆材林经营模型系统及优化栽培模式研究

It may not seem like much , but research shows that one ton of recycled paper could save 17 pulpwood trees 虽然看起来不多，可是研究显示回收一公吨纸得以保全17棵用来造纸的树木！
5.
The results showed that stem volume ( v ) and wood basic density ( bd ) were the most important traits in selection breeding for pulpwood of masson pine and , stand and individul selections shoud be based on the provenance selection 结果表明，马尾松制浆造纸材的良种选育应以材积和木材基本密度作为主要指标，首先进行种源的选择，在此基础上进行林分和个体的选择。

Genetic variations in different levels of masson pine ( pinus massoniana lamb . ) in main traits were studied on the basis of the 12 - year - old data of provenance tests at 7 test locations and the 11 - year - old data of plus progenies at 2 test locations , and the index and strategy in different variation levels on selection breeding for pulpwood in masson pine was also discussed 以7个试验点12年生马尾松种源试验林及2个试验点11年生优树子代测定林为基础材料，在研究马尾松主要性状不同层次遗传变异的基础上，对马尾松制浆造纸材良种选育目标及在不同变异层次的选择策略进行了探讨。
