摘要
根据野外测定资料,分析了小老树林地土壤水分和养分状况及其对树木生长的影响,结果表明,土壤水分亏缺是小老树形成的重要因子,土壤肥力不足和不平衡也是一个重要因子,它不仅影响树木生长,而且还影响土壤水分的利用。
The status of soil moisture and nutrients in small-old-tree stan- ds and its impact on tree growh are analysed on the basis of field data. The result indicateed,the soil water deficits is an important factors for the small-old-tree,but low soil fertility and imbalance of nutrients are also significant factors.The inadequate soil nutrient not only impacted on tree growth,and on utilizing of soil moisture.
