| 摘 要： | 为了提高林地生产力,满足经济社会发展对杉木大径材的需求,采用不同抚育措施和测土配方平衡施肥技术,研究其对土壤养分变化和杉木胸径的影响。结果表明：间伐措施对土壤养分的影响不明显;测土施肥处理,与不施肥相比,有效促进了土壤碱解氮、有效磷、速效钾的积累,改善了土壤肥力水平。采取间伐施肥措施能显著增加杉木大径材胸径的生长,两年平均增加了3.43 cm,其中：平衡施肥带来的平均胸径增加量分别为1.03 cm;间伐带来的平均胸径增加量分别为2.4 cm。培育杉木大径材应实施间伐与测土施肥相结合的抚育措施。

| Abstract: | In order to improve land productivity, meet the needs of Chinese fir large-diameter timber for economic and social development, using different tending measures and balanced fertilization and soil testing techniques, research and there impact on soil nutrient changes and fir DBH. The results showed that： thinning measures on soil nutrients obvious; soil fertilization treatment, compared with no fertilizer, effectively promoting soil nitrogen, phosphorus, potassium accumulation, improving soil fertility levels. Take thinning and fertilization can significantly increase the diameter of the large diameter timber fir growth, two years increased by an average 3.43 cm, which： increase the amount of balanced fertilization average diameter of 1.03 cm were brought;increase the amount of thinning bring average DBH were 2.4 cm. Fir cultivation should be implemented large-diameter timber thinning and tending soil testing, fertilizer combine. |
