摘　　要：针对长期以来缺乏山皂荚优良品种的现状,笔者依据优树选择目标及标准,经过优树选择、苗期试验、无性系测定、区域试验选育出了山皂荚新品种。结果表明,晋皂2号为生态防护优良树种,生长速度快、抗逆性强,嫁接苗10年生平均树高7.11 m,平均胸径8.18 cm。晋皂3号为城乡绿化优良树种,荚果丰硕、扭曲度大,观赏性强,嫁接苗10年生平均树高6.55 m,平均胸径7.83 cm。这2个山皂荚良种适应性强,应用前景广阔,在山西省海拔1 200 m以下的地区均可栽培。To improve the current situation of lack of good varieties of Gleditsia japonica, new varieties of Gleditsia japonica were selected by means of superior tree selection, seedling test, clonal test and regional test based on the superior tree selection target and standard. Results showed that Jinzao 2 was ecological shelterbelt species with fast growth and strong resistance, the average tree height and DBH of the 10-year-old grafting seedlings were 7.11 m and 8.18 cm. Jinzao 3 was superior greening tree species in urban and rural areas which had rich pods with a large twist angle and high ornamental value, the average tree height and DBH of 10-year-old grafting seedlings were 6.55 m and 7.83 cm. The 2 new varieties of Gleditsia japonica had strong adaptability and wide application prospect, which were suitable to plant in the areas under the altitude of 1 200 m in Shanxi Province.
