| 摘 要： | 调查江西省油茶主产区近年新造林地与自然林分的土壤理化状况,结果表明：油茶林地地貌类型分布主要集中在中丘、高丘和山地;油茶林地土壤类型主要是红壤,土层较厚,层次不清、腐殖质少、块状结构、质地较粘;山地养分一般高于丘陵,丘陵高于岗地,平原人为耕作影响养分含量较高。N、K、pH值和代换性盐基随海拔增高呈升高趋势,P变化不明显;土壤养分差异比较大,大部分养分指标最大值与最小值相差约10倍。油茶林地土壤养分含量均比较低,尤其是P,其次是N、K,盐基代换量也比较低,林地的保水保肥能力差。

| Abstract: | The soil physical and chemical properties of new plantation and natural forests in main product area of Camellia oleifera in Jiangxi Province in recent years were investigated in this article.The results showed that the distribution of the geomorphological types of C.oleifera mainly concentrated in the moderate hilly,high hilly and mountain areas;The soil types of C.oleifera were chiefly red soil which with thick soil,indistinct layers,little humus,blocky structure and rather sementitious;the soil nutrient ... |
