摘要
通过马尾松毛红椿混交林和马尾松纯林生长量和土壤肥力状况的对比研究,结果表明,马尾松毛红椿混交林中马尾松胸径、树高、单株材积和总蓄积量均高于马尾松纯林。混交林中马尾松和毛红椿的生长量呈现出马尾松毛红椿混交比例4∶1>3∶1>2∶1的规律。马尾松毛红椿混交林土壤水分物理性质和化学性质均优于马尾松纯林,营造马尾松毛红椿混交林有利于提高土壤肥力。由于毛红椿生长快于马尾松,营造混交林以带状混交为佳,且毛红椿比例宜小。
Abstract：Through the research on the growth and soil fertility of the mixed stand of Pinus massoniana and Toon ciliata var. pubescens compared with the pure stand of Pinus massoniana, the results indicate that DHB,height,individual volume and stand volume of pinus massoniana in mixed stand of Pinus massonlana and Toona ciliata var. pubescens is more than that of the pure stand of Pinus massoniana respectively. The growth increment of Pinus massoniana and Toona ciliata var. pu- bescens in mixed stand show the regularity of4：1 〉 3：1 〉 2：1. The water-physical character of soil of the mixed stand is better than that of the pure stand. The model of belt mixed is suitable to be adopted when the mixed stand of Pinus massoniana and Toona ciliata var. oubescens are planted.
