摘要
[目的]研究毛竹林中不同坡位和土层深度的土壤物理性质和基本化学性质,为高山地区毛竹林经营提供科学依据。[方法]以闽北高山地区的毛竹林土壤为对象,按坡位采集土壤样品,分析相关理化指标。[结果]毛竹林上坡、下坡土壤物理性质优于中坡土壤,土壤有机质、碱解氮、速效磷、速效钾、有效硼、有效铜、有效铁含量随坡位和土层深度的增加大致呈下降趋势,有效硅含量随土层深度的增加而增加,总体看毛竹林中坡土壤物理性质较差,养分流失严重,下坡土壤理化条件较为理想。[结论]在毛竹林经营过程中,应特别注重加强对中坡的治理防护,防止土壤退化。
[Objective] To study the effects of slope position and soil depth on the soil physical and chemical properties and basic chemical property of moso bamboo forest,and to provide scientific basis for the management of high-mountain moso bamboo forest. [Method] By taking the soil in high-mountain moso bamboo forest in north of Fujian as test materials,soil samples of the different slope positions were collected and analyzed. [Result] The physical properties of soil at lower slope and upper slope were better than those at the middle slope. With the increase of soil depth and slope position,the content of organic matter,N,P,K,B,Cu and Fe decreased,but the content of Si raised with increase of soil depth. It was proved that the physical and chemical properties was the highest at the lower slope position,and worst at the middle slope. [Conclusion] In the management of high-mountain moso bamboo forest,it is very important to strengthen the management of the slope protection to prevent soil degradation.
