摘要:
山地水平带不同空间位置土壤存在差异，对香榧Torreya grandis‘Merrillii’生长有较大影响。对比研究了 浙南山地水平带不同位置种植的香榧生长势及土壤理化性质的差异性。结果表明：水平带外侧种植香榧的根系深 度、冠幅、树高、地径、保存率分别高于内侧同期种植香榧的188.4%、93.8%、61.7%、57.3%、5.3%，投产所需 年份是内侧种植香榧投产所需年份的34.8%，呈现外侧种植香榧好于中间种植香榧、中间种植香榧好于内侧种植 香榧的普遍情况。通过对水平带不同位置土壤因子进一步分析发现：水平带不同栽植位置与香榧树体生长性状和土 壤理化性质均呈极显著相关（P＜0.01），土层厚度、土壤有机质含量均与香榧生长性状呈极显著正相关（P＜0.01）， 土壤含水率、容重均与香榧生长性状呈极显著负相关（P＜0.01）。水平带外侧的立地条件更优越，起垄、靠外侧、 浅栽高覆土，更有利于香榧生长，水平带中间适合林下套种立体经营，水平带内侧空间利于基地机械化经营。
Abstract:
In July 2020, determinations were carried out on ground diameter, crown width, height, root system depth of planted at different positions on mountain horizontal belt in Songyang, Zhejiang province. Meanwhile, soil of 20-40cm was sampled under T. grandis ‘Merrillii’. The result demonstrated that the root system depth, crown width, height, ground diameter and conservation rate of T. grandis ‘Merrillii’ planted in the outer side of the belt were 188.4%, 93.8%, 61.7%, 57.3%, and 5.3% higher than those in the inner side, and the years for production were 34.8% lower, showing that the outer side was better than the middle, and the middle was better than the inner side for plantation. Analysis on soil physiochemical properties at different planting positions showed that it had significantly correlation (P<0.01). The thickness of soil layer, soil organic matter content had significantly positive relation with growth of T. grandis ‘Merrillii’, while soil moisture content, bulk density was the opposite.
