闽中山地湿地松混交林经营效果的初步研究

Preliminary Study on the Management Effects of Pinus elliottii Mixed Forests in the Mountain Area of Central Fujian

对 2 1年生的湿地松与木荷混交林、16年生的湿地松与厚朴和湿地松与马尾松混交林的造林效果调查分析结果表明 :湿地松与木荷的混交是成功的 ,湿地松∶木荷以 3～ 5∶1的混交比例为宜 ,采用行带混交方式。湿地松与厚朴的混交效果不尽理想 ,2个树种的生长都欠佳。湿地松与马尾松以 8∶2的插花混交 ,两者生长较稳定 ,种间关系协调 ,混交效果较好。

The results indicate that the mixture of Pinus elliottii and Schima superba is successful,it is suitable that the mixed proportion of P.elliottii and S.superba is 3～5 trees to 1 tree and the mixed modes of lines and strips are adopted;the mixed effects of P.elliottii and Magnolia officinalis are less than satisfactory and the growth of these two species is not good enough;and P.elliottii and P.massoniana are mixed up with the proportion of 8 trees to 2 trees,the growth of both species is relatively stable,their interspecific relation is coordinative and their mixed effects are comparatively good.
