摘要:
为探讨配方施肥对马尾松 Pinus massoniana 人工林生长、叶片和土壤肥力的影响，以 8 年 生马尾松人工林为研究对象，设置 5 个施肥处理，对不同处理后马尾松的树高、胸径、叶片营养、土 壤养分等进行了比较分析，并运用灰色关联度法对马尾松人工林叶片营养和土壤肥力状况进行综合评 价。结果表明：林地配方施肥具有促进 8 年生马尾松人工林树高和胸径生长的效果。施肥 2 年后，最 佳的施肥处理 T2（N:P2O5：K2O=8:10:12）的树高、胸径年均增长量达 1.25 m、1.29 cm，分别比不施 肥处理 CK 高 61.54% 和 35.79%。而不同施肥处理对土壤肥力和叶片营养含量的促进效果大小顺序分 别 为：T2（N:P2O5:K2O=8:10:12） ﹥ T4（N:P2O5:K2O=10:10:10） ﹥ T3（N:P2O5:K2O=12:8:10） ﹥ T1 （N:P2O5:K2O=7:14:9）﹥ CK、T2 ﹥ T3 ﹥ T4 ﹥ T1 ﹥ CK。不同施肥处理中处理 T2 对 8 年生马尾松人工 林生长指标、叶片营养和土壤肥力的促进效果最佳，而 CK（不施肥）处理的生长表现最差，其土壤肥力 严重退化，叶片营养缺素明显。

Abstract:
In order to explore the effects of formula fertilization on the growth, leaf, and soil fertility of masson’s pine plantation, the tree height, DBH, leaf nutrition, and soil nutrients of the 8-year-old Masson pine plantation were compared and analyzed with 5 fertilization treatments. The grey correlation degree method was used to evaluate the leaf nutrition and soil fertility of Masson pine plantation. The results showed that the forest formula fertilization could promote the growth of tree height and DBH of an 8-year-old Masson pine plantation. After 2 years of fertilization, the average annual increase in tree height and DBH in the best treatment T2 （N ∶ P2O5 ∶ K2O=8 ∶ 10 ∶ 12）was 1.25 m and 1.29 cm, which were 61.54% and 35.79% higher than that in the CK without fertilization, respectively. The order for promoting effects of different fertilization treatments of soil fertility and leaf nutrient content was as follows: T2（N ∶ P2O5 ∶ K2O = 8 ∶ 10 ∶ 12）> T4（N ∶ P2O5 ∶ K2O = 10 ∶ 10 ∶ 10）> T3（N ∶ P2O5 ∶ K2O = 12 ∶ 8 ∶ 10）> T1（N ∶ P2O5 ∶ K2O = 7 ∶ 14 ∶ 9）> CK, T2 > T3 > T4 > T1 > CK. Among different fertilization treatments, treatment T2 had the best promotion effect on growth index, leaf nutrition, and soil fertility of 8-year-old Masson pine plantation, while CK（without fertilization） had the worst growth performance, with serious degradation of soil fertility and obvious leaf nutrient deficiency.
