为了檫木正确有效地在豫南地区推广 ,通过对豫南引种檫木在各种立地条件下的生长调查 ,摸清了檫木的适应性 .根据立地、生长调查结果 ,分析了立地对檫木生长的影响 ,即檫木生长因立地变化而变化 ,其中风口对檫木生长有明显影响 ,土层厚度和腐殖层厚对檫木生长有极显著影响 ,土壤质地和石砾含量对檫木生长有显著影响 ,而海拔高、坡向、坡位等地形因子的影响不显著 .
In order to promote Alnus cremastogyne correctly and effectively in southern Henan, the adaptability of Alnus cremastogyne was found through the investigation on the growth of Alnus cremastogyne introduced in south of Henan Province.According to the site survey and growth survey, The effect of wood growth, that is, Alnus cremastogyne growth varies with site change, of which the tuyere has a significant effect on Alnus cremastogyne growth, soil thickness and humus layer thickness have a very significant impact on the Alnus cremastogyne growth, soil texture and gravel content Wood growth has a significant impact, while the altitude, slope, slope and other topographical factors have no significant effect.
