| 摘 要： | 对定植3年的思茅松人工林进行施肥试验, 结果表明: 施肥对思茅松幼林的林木高、径生长有一定的促进作用, 但需N、P、K肥配合施用。在一般立地条件下, 思茅松幼林追肥较为合理的施肥用量为: 尿素50g/株; 过磷酸钙200g/株, 硫酸钾50g/株。此外, 合理施肥能够保持思茅松人工林地的土壤肥力, 以至提高林地土壤的养分含量。 |
| 关 键 词： | 思茅松 人工幼林 施肥效应 |

| Abstract: | Fertilization experiment on the Pinus kesiya var.langbianensis plantation of 3 years old having been planted permanently was carried out, and the result showed that the fertilization had accelerated the growth of tree height and that of diameter at breast height of the plantation to a certain degree on condition that the nitrogen fertilizer, phosphate fertilizer and potash fertilizer were coordinated and applied. On general site condition, the relatively reasonable application rates of additional manuring for the young plantation of Pinus kesiya var.angbianensis were as follows: urea of 50g/tree, super phosphate of 200g/tree and potassium sulphate of 50g/tree. In addition, rational fertilization can maintain the soil fertility of artificial forest land of Pinus kesiya var.angbianensis and even raise the soil nutrient content of the forest land. |
