| 摘 要： | 对定植3年的思茅松人工幼林进行追肥试验，结果表明．施肥对思茅松高、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，思茅松追肥较为合理的施用量为：尿素50g／株；过磷酸钙200g／株，硫酸钾50g／株。此外，合理施肥能够保持甚至提高土壤养分含量。

| Abstract: | A additional fertilizer trial was carried on the Pinus kesiya var. langbianensis planted forest stand of 3 years old,the result shows that fertilization has certain acceleration effect for the growth of tree height and diamete of young Pinus kesiya var. langbianensis trees,but should be matched with N,P and K fertilizer.Under the general site condition,the relatively reasonable amount of applied additional fertilizer for Pinus kesiya var. langbianensis is:Urea 50g/tree;Calcium superphosphate 200g/tree,Potassium sulfate 50g/tree.In addition,rational application of fertilizer can maintain the Pinus kesiya var. langbianensis planted forest soil fertility even to enhance the soil nutrient content. |
