Abstract

Abstract:

Tree species affect soil inorganic nitrogen content through litter input and root activity, which plays an important role in regulating soil fertility. However, the impact of different tree species on soil fertility is uncertain. In order to study the effects of native tree species on the soil ecological process, a common garden experiment was established. Cinnamomum japonicum, Cinnamomum longipaniculatum, Cinnamomum austrosinense, Alnus cremastogyne, Cinnamomum Camphora, Toona ciliata and Toona sinensis were taken as the research objects. Compared with abandoned land, the content of soil inorganic nitrogen and the common physical and chemical properties of soil in three soil layers (0-10 cm, 10-20 cm, 20-30 cm) and their effects of tree species and soil layers on soil inorganic nitrogen contents were analyzed. The results show that (1) compared with abandoned land, the soil inorganic nitrogen content of C. austrosinense, C. japonicum, T. ciliateand and A. cremastogyne increased by 27.6%, 27.4%, 26.4% and 19.3%. The inorganic nitrogen content of C. camphora increased by 2.4%, while the C. longipaniculatumr and T. sinensis significantly decreased by 8.1% and 8.9%. (2) The contents of soil inorganic nitrogen contents in the soil of 7 tree species decreased with the increase of soil depth, while NH₄⁺-N/NO₃^--N showed an opposite trend of change, which was most obvious among A. cremastogyne, C. phatyphyllum, C. japonicum, T. sinensis and T. ciliate. (3) Soil physical indexes (e.g., texture and bulk density) and chemical indexes (e.g., pH, C:N, C:P, microbial biomass N) were significantly correlated with soil inorganic nitrogen. Redundancy analysis (RDA) indicated that soil clay particle, total organic nitrogen and microbial biomass nitrogen contents were the main driving factors causing changes to soil inorganic nitrogen. In conclusion, tree species predominantly altered soil inorganic nitrogen contents by changing soil physical and chemical properties. The influence of tree species on soil inorganic nitrogen content was greater than that of soil layer. Compared with other species, C. austrosinense, C. japonicum and T. ciliata were more beneficial to the maintenance of soil nitrogen nutrients.

摘要：

林木通过凋落物输入及根系活动等过程影响土壤无机氮含量，从而对调控土壤肥力有重要作用，但目前不同树种间对其有何影响仍不清楚。为探究四川盆地乡土树种对土壤无机氮含量的影响机制，采用同质园试验，以红椿（Toona ciliata）、香椿（Toona sinensis）、天竺桂（Cinnamomum japonicum）、大叶樟（Cinnamomun phatyphyllum）、香樟（Cinnamomum camphora）、油樟（Cinnamomum longipaniculatum）和桤木（Alnus cremastogyne）7个阔叶树种为研究对象，以撂荒地为对照，采集了3个土层（0-10、10-20、20-30 cm）的土壤样品，测定铵态氮、硝态氮及其他常见的土壤理化指标，分析树种和土层对土壤无机氮含量的影响。结果表明，（1）相比撂荒地，大叶樟、天竺桂、红椿和桤木土壤无机氮含量分别显著增加了27.6%、27.4%、26.4%和19.3%，香樟、油樟和香椿无机氮含量则分别增加了2.4%和显著降低了8.1%和8.9%。（2）7个树种土壤无机氮含量总体随土层深度增加而下降，铵态氮/硝态氮则表现为相反的趋势，其中桤木、大叶樟、天竺桂、香椿和红椿表现尤为明显。（3）土壤物理参数（机械组成、容重）和化学参数（pH、碳氮比、碳磷比和微生物生物量氮）与土壤无机氮含量显著相关。冗余分析（RDA）进一步表明土壤黏粒、全氮和微生物生物量氮是引起土壤无机氮含量变化的关键影响因子。综上所述，树种通过改变土壤理化性质而影响土壤无机氮含量；树种效应大于土层效应；相比而言，大叶樟、天竺桂和红椿更有利于土壤氮养分的维持。
