马尾松武平种源生长优异性的试验研究

Experimental Study on the Growth of Pinus massoniana Provenance from Wuping

通过大面积中试林以及跟踪试验林5年生幼林生长性状的测试,武平种源不仅明显高于本省邵武种源,而且还优于两广优良种源。在参试的4个马尾松种源中,武平种源树高达4 42m、胸径6 03cm、材积16 85m3·hm-2,全株生物量34 9kg(其中树干占39 25%),均为各种源之首,生长量与生物量的优异性十分明显。

Through the growth characteristic test of 5yearold young forest in large aereage of pilot plantation,the provenance from Wuping not only is evidently higher than the one from Shaowu,Fujian,but also is more excellent than the fine one from Guangdong and Guangxi. In the 4 tested Pinus massoniana provenances,the provenance from Wuping reaches 442 m high,dhh is 603 cm,volume is 1685m3/hm2,the biomass of whole plant is 349kg,among which that of trunk stem accounts for 3925%,which are all the top of those of all provenances.
