不同立地条件三桠丰产栽培技术研究

Study on the High-yield Cultivation Techniques for Edgeworthia chrysantha in Different Sites

三桠作为一种综合效益较高的特用树种,广泛分布于安徽大别山南坡的岳西、潜山、太湖等地。本文通过对"四旁"、抛荒地、天然次生林下以及与其他经济林间作等不同条件下三桠丰产栽培技术的研究,特别是不同程度土壤积水试验研究表明,三桠不耐积水,过度积水胁迫了其生长。此研究为合理开发地方特色树种,科学选择其造林地,改善生态环境,提供了良好的技术基础。

Edgeworthia chrysantha, a special tree species with high comprehensive benefits, is widespread in the counties of Yuexi, Qianshan and Taihu and other areas in the southern slopes of Dabie Mountains in Anhui Province. In this paper, a study was made on the high-yield cultivation techniques for Edgeworthia chrysantha in different sites including the ＂four sides＂, derelict land, natural secondary forests, intercropped economic forests and waterlogged soil. The results showed that the species was vulnerable to waterlogged soil. Excessive water in soil inhibited its growth. The study provide technical basis for rational development of local characteristic tree species, scientific choice of forestation land and improvement of eco- environment.
