摘  要：
以花生间作杉木幼林纯林样地为研究对象,未间作林地为对照,选取广西种源2.5代实生苗(简称"广西-2.5")、福建种源无性系扦插苗-020(简称"福建-洋020")、福建种源无性系扦插苗-061(简称"福建-洋061")3个种源,对比分析花生间作对相应种源杉木幼林地土壤理化特性的影响。研究结果表明,所有样地的土壤容重均随着土层的加深而显著增大;花生间作对杉木幼林地的土壤物理指标影响变化幅度不大,相同杉木种源花生间作模式下林地土壤物理性状总体上优于未间作林地;花生间作模式提高了杉木幼林地的土壤p H值以及有机质、全N、碱解N、全P和速效P含量,全K和速效K含量略有降低,缓解了土壤酸化速率,提高了有机质含量。

摘  要：
Based on the research object of Arachis hypogaea intercropping in Cunninghamia lanceolata young plantation and the control of no intercropping,the three provenances of Guangxi 2. 5 generation( hereinafter referred to as"Guangxi-2. 5"),Fujian clonal cutting seedings-020( hereinafter referred to as "Fujian-Yang 020"),Fujian clonal cutting seedings-061( hereinafter referred to as "Fujian-Yang 061") were selected for the comparative analysis of effects of A. hypogaea intercropping on soil physicochemical properties in C. lanceolate young plantation. The results showed that soil volume-weight increased significantly with the deepening of the soil layer. The effect of A. hypogaea intercropping on the soil physical index was not significant. The soil physical properties of the same provenance intercropping were better than that of not intercropping. The intercropping pattern improved soil p H and content of organic matter,total nitrogen,available nitrogen,total phosphorus and available phosphorus while total potassium and available potassium content decreased slightly,which alleviated soil acidification rate and increased the content of organic matter.
