广西浪水马尾松种源栽培试验研究

广西浪水种源６年生幼林树高、胸径、材积生长量比本地种分别增长２１．８％、３１．２％、１２８％，且差异达到极显著、显著程度。用广西浪水种源种苗营建４００ｈｍ２世行贷款项目林都超过速生丰产林指标。本研究结果表明，从广西马尾松优良种源区引进浪水种源是成功的。

Experimental Study on Culturing Pinus massoniana Provenance from Langshui, Guangxi

The provenance from Langshui,Guangxi possesses the features of fast growth,extensive adaptability,etc.According to the experiment,the height,dbh and volume growth of 6 year old young forest of this provenance increase by 218%,312% and 128% respectively as compared with those of the local species and these differences are extremely significant or significant.Various indexes of 400hm2 of the project forests loaned by the Asian Bank planted with seeds and seedlings from the provenance of Langshui are all over those of fast growing and high yielding forest.The present study results indicate that introducing Langshui provenance from the excellent provenance area of Pinus massoniana in Guangxi is successful.
