| 摘 要： | 对思茅松人工林幼林期(1~4年生)林地土壤肥力的定位监测结果表明:营造思茅松人工林,只要合理施肥,就能有效地维护其林地土壤的肥力。其经营过程中施用尿素能够显著提高思茅松人工林林地土壤的养分含量,改善其土壤的化学性质;施用过磷酸钙和硫酸钾对思茅松人工林林地土壤肥力的影响不显著,但当其施用量达到一定水平时也能防止林地土壤的退化。

| Abstract: | Through fixed plot monitoring on soil fertility of 1 to 4 years old Pinus kesiya var.langbianensis plantation,it was found that under the proper fertilization measures,the fertility of forest land soil could be effectively maintained.The content of soil nutrients can be significantly increased and the soil chemical characteristics can be improved by applying urea.There is no significant effects on soil fertility by applying calcium superphosphate and potassium sulfate,however the soil degradation can be prevented to some extend. |
