| 为探讨在闽南杉木边缘产区不同阔叶树种与杉木混交对林分生长及土壤肥力的影响,选择桉
树、红锥、火力楠3种本地主要阔叶用材树种与杉木营建混交比例为70%杉木∶30%阔叶树的混交林,以杉木纯林为对照,对比不同林分生长量及土壤肥力状况。结果表明,不同处理林木保存率均
达到86.54%以上,4个参试树种生长量均较高,整体生长表现良好;杉木胸径、树高和材积最高的均为处理3,处理3和处理4杉木胸径、树高和材积均显著高于对照;参试的3个混交林处理中,林地土壤肥力状况表现最优的是处理3,其次是处理4,再次是处理2,相比杉木纯林,3个混交林处理的林地土壤养分含量得到不同程度提高,土壤肥力得到改善。综上所述,以红锥、火力楠作为混交
树种与杉木营造混交林,均可以有效提升杉木生长量并改善土壤肥力状况。 |

| To investigate the effects of mixed plantations of Cunninghamin lanceolata with different broadleaved
tree species on stand growth and soil fertility in the edge production area of southern Fujian, mixed
forests of 70% C. lanceolata and 30% broad-leaved tree was constructed by selecting three main local afforestation
tree species, Eucalyptus, Castanopsis hystrix, and Michelia macclurei. The pure C. lanceolata
forest was used as a control to compare the growth and soil nutrient content of different forest stands. The
results showed that the preservation rate of trees under different treatments reached over 86.54%, and the
four tested tree species grew well. Treatment 3 yielded the highest values for diameter at breast height
(DBH), tree height, and timber volume of C. lanceolata. Both Treatment 3 and Treatment 4 exhibited
significantly greater DBH, tree height, and timber volume of C. lanceolata compared to the control. Among the three mixed plantation treatments, Treatment 3 demonstrated the best soil fertility conditions,
followed by Treatment 4 and then Treatment 2. Compared to the pure C. lanceolata plantation, all three
mixed treatments resulted in varying degrees of improvement in soil nutrient content and soil fertility. In
conclusion, using mixed tree species such as C. hystrix and M. macclurei to create mixed forests with
C. lanceolata could effectively increase the growth of C. lanceolata and improve soil fertility. |
