摘  要：
为探讨目标树经营对杉木人工林生长及土壤肥力的影响,以14年生杉木中龄林为对象,设计目标树经营(TM)、目标树施肥经营(TF)、传统经营对照(CK)3种经营模式,开展目标树经营对杉木生长和土壤肥力影响研究。结果表明,与对照相比,TM、TF经营模式一定程度上促进了杉木树高、胸径、单株材积年均增量,其中,杉木单株材积年均增量分别显著增加0.030 6、0.031 6 m~3。目标树经营模式显著影响0～10 cm土层肥力指标,均呈现出TF>TM>CK。其中,TM模式下的土壤水解性N、有效P、速效K分别比对照增加7.1%、9.2%、24.9%,而TF模式下分别增加15.2%、9.5%、30.7%。同时土壤脲酶、蔗糖酶、过氧化氢酶活性增强。综上所述,目标树经营模式能够改善杉木人工林的土壤肥力,提高杉木的生长质量,为杉木人工林可持续经营提供了理论依据。

摘  要：
In order to study the effects of target tree management on the growth and soil fertility of Cunninghamia lanceolata plantation, 14-year-old C.lanceolata plantation was taken as the study object, three management modes were designed to conduct the experiment, including target tree management(TM),target tree fertilization management(TF),and traditional management(control).The results showed that TM and TF promoted the annual increment of tree height, DBH and single tree volume to a certain extent, and the annual increments of single tree volume significantly increased by 0.030 6 m~3(TM) and 0.031 6 m~3(TF),respectively.The management mode significantly affected the soil fertility indices of 0-10 cm soil layer, and with the order of TF>TM>control.Under TM mode, the soil hydrolytic N,available P and available K increased by 7.1%,9.2% and 24.9%,respectively.Under the TF mode, the corresponding increments were 15.2%,9.5% and 30.7%,respectively.At the same time, the activities of urease, sucrase and catalase increased.It was concluded that the TM and TF modes could improve the soil fertility and promote the growth of Chinese fir.The results provide the theoretical basis for sustainable management of Chinese fir plantation.
