摘要
文章通过对杉木林采伐迹地人工营造毛竹厚朴混交林土壤理化性质的分析研究,结果表明:在杉木林采伐迹地内人工营造毛竹厚朴混交林,不同坡位不同土层的pH值均有所升高。土壤有机质含量、土壤速效氮、速效磷及速效钾等养分含量也有所增加;表层土壤速效氮及速效磷含量增加幅度表现为中腹>下腹>上腹。由此可知,在杉木林采伐迹地内人工营造毛竹厚朴混交后,能较好的培肥土壤,改善土壤理化性质。
In this paper,soil physical and chemical properties in mixed plantations of Phyllostachys heterocycla cv.pubescens and Magnolia officinalis on cutting-over lands of Cunninghamia lanceolata were analyzed.The results indicated that： pH values in different soil layers on different slope positions were elevated in mixed plantations of Phyllostachys heterocycla cv.pubescens and Magnolia officinalis on cutting-over lands of Cunninghamia lanceolata,and contents of organic matter,available N,P and K in soils were also increased.The increase rates of available N and P in surface soil layers were as the following order： middle parts of slopes,lower parts of slopes and upper parts of slopes.Therefore,mixed plantations of Phyllostachys heterocycla cv.pubescens and Magnolia officinalis on cutting-over lands of Cunninghamia lanceolata could enhance the soil fertility and improve soil physical and chemical properties.
