摘要
对马尾松木荷混交林与马尾松纯林林分生长、径阶分布及土壤理化性质研究表明 :马尾松与木荷以 2∶1比例行状混交 ,马尾松生长快 ,林分各径阶呈正态分布 ,林分生产力高、结构稳定。马尾松木荷混交林不仅提高土壤通透性和蓄水性 ,促进土壤良好结构形成 ,而且增加土壤养分含量 。
The growth and diameter distribution of Mixed Pinus massoniana and Schma superbe Forest and pure Pinus massoniana forest as well as the physical and chemical property of soil in these forest were studied. The results indicated that in the mixed forest by proportion of 2:1 the Pinus massoniana grew quickly and the diameter presented a normal distribution, with a high productivity of stand and a stable structure. It is concluded that this mixed forest not only can improve the permeability and water storage of soil but also increase the fertility of soil.
