杉木不同优树材性的比较研究

Comparative Stndies on Wood Properties for Different Superior Trees of Chinese Fir.

通过对浙江省临安县和龙泉市各１５株杉木子代优树材性测试和综合评定，认为临７５，临５，龙７，龙２５和龙２６号是优良的工程用材优树；龙２３，龙２５，龙２８和临７８号是优良的制浆造纸用材优树。其中龙２５号是两者兼优的优树，临７８和龙２６号是两者较好的优树。

Based on the examination of wood properties and combined evalua-tion for the progenies of 30 Chinese fir superior trees from Lin’an Countyand Longquan City,Zhejiang Province(15 trees from each site),theauthors considered that the numbers Lin75, Lin5, Long17,Long25 and Long26as the superior trees for engineering technique timber production,and thenumbers Long23,Long25,Long28 and Lin78 as the superior trees for pulp-wood production,all are good.Among these the Long25 is tbe best,and theLin78 and Long26 are the better trees for both uses.
