| 摘 要： | 通过对北京中山公园300年以上古侧柏良好树与衰弱树土样的采集,分析土壤矿质元素对古侧柏生长的影响,探讨适合古侧柏生长的根际环境的标准值。结果表明,古侧柏生长的最佳立地条件为:有机质1.32%～1.49%,全盐0.038%～0.059%,pH 8.17～8.46,碱解N 50.63～62.52 mg/kg,速效K 115.93～140.42mg/kg,有效P 11.00～15.29 mg/kg,Fe 4.45～6.02 mg/kg,Mn 7.62～8.29 mg/kg,Cu 12.26～18.71 mg/kg,Zn5.95～7.08 mg/kg,水溶性Na 15.60～17.03 mg/kg。这为古侧柏保护复壮提供参数。

| Abstract: | Collection of the soil samples over age of 300 years oriental arborvitae in Beijing Zhongshan Park, the influence of soil mineral elements on the growth of ancient oriental arborvitae were analyzed, and at the mean time the influence element stan- dard value which was suitable for the age-old oriental arbor-vitae grows were discussed. The best site conditions of ancient oriental arborvitae were organic matter 1.32% - 1.49%, salt 0.038% - 0.059%, pH 8.17 - 8.46, alkali solution for N 50.63 - 62.52 mg/kg, available K 115.93 - 140.42 mg/kg, available P 11.00 - 15.29 mg/kg, Fe 4.45 - 6.02 mg/kg, Mn 7.62 - 8.29 mg/kg, Cu 12.26 - 18.71 mg/kg, Zn 5.95 - 7.08 mg/kg, water-soluble Na 15.60 - 17.03 mg/kg. It has provided the parameter for the ancient oriental arborvitae protection and rejuvenation. |
