摘要：在湖北省太子山林场进行木荷家系引种栽培试验，调查分析7个家系的成活情况和早期生长状况，并初步筛选出适合当地栽培推广的优良家系。结果表明：不同家系间成活率、保存率、胸径、冠幅均差异显著，且胸径、树高、冠幅三者间的相关性极显著；最适宜太子山林场栽培的优良家系为A06，其次为A04、A08、A02，建议进一步调查和推广试验。

Abstract： Seven families of Schima superba were introduced and cultivated in Taizi Mountain Forest Farm in Hubei Province， and the survival condition and early growth performance were analyzed to select suitable families for the local area. The results showed that there were significant difference among survival rates， preservation rates， diameter at breast height （DBH）， and crown width of each family. In addition， there was an extremely significant correlation among DBH， tree height， and crown width. The results also indicated that the most suitable family for Taizi Mountain Forest Farm was A06， followed by A04， A02， and A08 which should be further studied and popularized.

木荷Schima superba山茶科木荷属常绿大乔木＼[1＼]，广泛分布于我国南方各省区[2]，包括江苏、安徽、浙江、福建、江西、湖南、广东、海南、广西、贵州等地，是我国南方重要的珍贵优质阔叶用材树种、生物防火和高抗生态防护树种。木荷幼树耐荫，大树喜光，具有速生、丰产、材质优良和适应性强等特点[3]，其树干通直，结构均匀，材质坚韧致密，不开裂，易加工，是纺织工业中制作纱绽、纱管的上等材料，又是桥梁、船舶、车辆、建筑、农具、家具、胶合板等优良用材，树皮、树叶含鞣质，可以提取单宁。太子山区域内森林以针叶林为主，树种结构单一，且现有杉木二代林生长欠佳。为了改善林分现状，优化林区树种结构，提高森林质量，特引进优质阔叶树种木荷进行家系试验，研究其适应性及生长规律，选出适宜太子山气候及立地条件的优良家系，为进一步栽培推广提供理论依据。
