| 摘 要： | 三年来的马尾松幼林施肥试验结果表明，马尾松幼林理想的施肥处理是磷肥处理，单施磷肥马尾松幼林树高增益２０．５％～２２．２％，地径生长增益１９．８％～２０．８％；理想的施肥总量是Ｐ２Ｏ５０ｋｇ／ｈｍ２，即造林当年施基肥Ｐ２Ｏ５２５ｋｇ／ｈｍ２，造林后第３年再追施Ｐ２Ｏ５２５ｋｇ／ｈｍ２；立地低下的地方可适当配合施些氮肥；马尾松幼林不必施钾肥。

| Abstract: | The results of the fertilization experiment of Pinus massoniana for three years show that the treatment of applying phosphate fertilizer is the most effective for the growth of P.massoniana young plantations and applying phosphate fertilizer alone brings an increase of 20 5～22 2% in height growth and 19 8～20 8% in ground diameter;the ideal total fertilization amount is 50kg of P 2O 5 per hm 2,i.e. 25kg of P 2O 5per hm 2 as base fertilizer in the same year of the planting and 25kg of P 2O 5 by top application per hm 2 in the third year after the planting;and some nitrogenous fertilizer can be applied along with phosphate fertilizer in the areas with poor site conditions whereas potash is not needed for P.massoniana young plantations. |
