福建中部丘陵山地湿地松大径材培育技术

在福建中部丘陵山地通过湿地松引种栽培试验研究,结果表明:该树种生长较快,适应性强。通过集约管护30 a,其平均树高、胸径及蓄积量分别可以达到16.8 m、32.0 cm与581.0 m3,与一般造林(对照)的湿地松林分平均树高、胸径及蓄积量14.3 m、24.3 cm、282.6 m3相比,分别增长17.5%、31.7%与105.6%,是福州市郊较大面积引种湿地松培育大径材成功的实例,具有很好的应用推广前景。

Cultivation Technology of Large Pole of Pinus elliottii on Hilly Mountains in Middle Part of Fujian

Introduction cultivation experiments of Pinus elliottii on hilly mountains in middle part of Fujian were conducted.Results showed that this tree species grew faster and had stronger adapatability.By intensive managing and protecting for 30 years,mean tree height,DBH and volume of Pinus elliottii could reach 16.8m,32.0 cm and 581.0 m~3 and increased respectively 17.5%,31.7%and 105.6% comparing with mean tree height,DBH and volume of the general afforestation(CK) of stand of Pinus elliottii (14.3m,24.3cm,282.6m~3).It was a successful example of cultivating large pole by introducing Pinus elliottii in larger area in Fuzhou city.
