摘要
对杉木人工纯林,杉木与马尾松、木荷、厚朴构成的混交林下土壤物理性质和化学性质进行了测定和比较分析。结果表明,混交林能有效地改善林地土壤结构,提高土壤有机质和营养元素的含量,并通过降低土壤酸度,增加了养分有效性。在所研究的三种混交模式中,以杉木与木荷混交为最佳选择。
The physical and chemical properties of the soils supporting pure Cunninghamia lanceolata plantation and its respective mixed plantations with Pinus massoniana,Schima superba,and Magnolia officinalis,were measured and analyzed.The results showed that establishment of mixed plantations improved structure and nutrient status of the soils.The nutrient availability was increased due to declined soil acidity.Furthermore,the mixed pattern of Cunninghamia lanceolata with Schima superba was considered to be the best one among the three mixed patterns.
