| 摘 要： | 该文对广西不同地点江南油杉人工林土壤养分状况进行了比较研究。结果表明：8个样地中，0-10cm土层和10-20cm土层均以六万林场2样地土壤有机质含量最高；有机质、有机氮、全磷、全钾含量受样地坡度、海拔及坡向影响较大，坡度较大的样地土壤有机质、有机氮、全磷含量较高，海拔较高的样地全钾含量较高。该研究结果为江南油杉人工林培育提供了科学的理论依据。

| Abstract: | Soil nutrient in different location of Guangxi were be measured in this paper.The results indicated that, the concentration of soil organic in Liuwan forest far 2 was highest in both 0-10cm and 10-20cm layers, concentration of soil organic C,N,P and K were influenced by slope ,elevation and slope direction. Soft organic C, N and Pin great slope plot were higher than that in smaller slope plot, and K was present same trend in different altitude. This paper provided theoratical foundation for the breeding of Keteleeria cyclolepis plantation. |
