| 摘 要： | 目的]为森林的科学经营提供依据。方法]对肖坑地区常绿阔叶林、竹纯林、马尾松林下0~10、10~20、20~30 cm土壤的含量进行测定,研究不同林分土壤的养分状况。结果]3种林分土壤的全氮、全磷含量随土层的加深而降低,全磷、速效磷含量及10~20 cm土层的全氮含量差异明显,全氮含量的变异幅度为0.09%~0.23%。竹纯林土壤全磷含量最高,常绿阔叶林最低;常绿阔叶林土壤有效磷含量最高,马尾松林最低。常绿阔叶林土壤钾含量随土层的加深而增加,竹纯林土壤钾含量在10~20 cm土层中最高,马尾松林土壤钾含量在各土层中变化不大。3种林分土壤偏酸性,马尾松林土壤pH值最低。结论]不同林分土壤养分含量存在一定差异。

| Abstract: | Objective] The aim was to provide the basis for scientific management of forest.Method] The soil nutrient conditions in different forests were studied through the detection on the content of N,P and K in soil with depths of 0-10,10-20,20-30 cm under 3 types of forests of evergreen broad-leaved forest,bamboo pure forest and masson pine forest in Xiaokeng area.Result] The content of total nitrogen and total phosphorus under the 3 types of forests decreased with soil depths.There was significant difference among the contents of total phosphorus,available phosphorus and total nitrogen in soil with depths of 10-20 cm.The variation of total nitrogen content was 0.09%-0.23%.The total phosphorus content in the soil under bamboo pure forest was highest and that under evergreen broad-leaved forest was lowest;the available phosphorus content in the soil under evergreen broad-leaved forest was highest and that under masson pine forest was lowest.The potassium content in the soil under evergreen broad-leaved forest changed slightly in each soil layer.All soils under 3 types of forests were acid and the pH in the soil under masson pine forest was lowest.Conclusion] The soil nutrient content under different forests existed certain difference. |
