珍稀树种庙台槭的扦插繁殖及观赏特性研究

Cutting Propagation and Ornamental Features of Rare Species Acer miaotaiense

庙台槭为中国特有种,已处于濒危状态。通过野外调查、引种试验分析、扦插繁殖试验分析证明,庙台槭的枝栓、叶形、果形独特,可整形性强,观赏性好;在黄绵土、年均温10.7℃、年均降雨量531 mm、年均空气湿度70%、全光照条件下生长良好,可在相同或相似环境条件下栽培;采用1年生枝做插穗、耕种土腐殖质土混合土(1∶1)、塑料膜+遮荫网保护等措施后,可使成活率达到30%。庙台槭的园林观赏特点、较好的环境适应性及可人工扩繁使其具备了园林利用的可行性,可以在园林造景中开发利用。

The Acer miaotaiense is a peculiar species in China. It has already been placed in endangered state. Planting tests have proved that it is a fine ornamental tree species for its peuliar features in branch leaf, and fruit shapes, and brown trunks phellem. It can grow well in loess areas with, 10.7℃ annual mean temperature, 531 mm annual mean rainfall, and 70% annual mean air humidity under full sunlighp. The propagation experiment had been successful under the following conditions： using t-year-branch cuttings, farming-humus mixed soil （1： 1）, plastic membrane ＋ shading network protection, the survival rate was up to 30%.
