试验设在项目区的左权、榆社、和顺三县，通过高接园和新建园两种试验示范园的形式，引进国内１２个最新选育出的早、晚实核桃新品种，经过六年的试验研究，从坚果品质、丰产性能和适应性三个方面进行了筛选。认为：中林３号、薄丰、薄壳香、辽宁１号、晋龙１号、晋龙２号六个品种抗寒、耐旱、抗病性强，适宜在太行山区海拔１０００ｍ以下的干旱气候条件下发展。对于土壤瘠薄、立地条件较差的地方，应加强土壤改良，增施有机肥和树盘覆盖。保水肥田、合理负担是太行山区发展核桃生产的关键性措施。
The experiment was carried out in the Zuoquan, Yushe and Heshun three counties in the project area. Through the experimental and demonstration parks of Gaolinkuan Park and Xinjiangyuan Park, the newly introduced 12 varieties of early and late real walnut varieties were introduced. After six years Of the pilot study, from the nut quality, high yield performance and adaptability in three aspects were screened. The results showed that the drought resistance, drought tolerance and disease resistance of six varieties Zhonglin 3, Biefeng, Xiangfanxiang, Liaoning No.1, Jinlong No.1 and Jinlong2 are suitable for the drought in the Taihang Mountains with the altitude below 1000m Develop under climatic conditions. For infertile soil and poor site conditions, soil improvement should be strengthened and organic manure and tree-plate cover should be added. Watering fertile fields, a reasonable burden is the key measures for the development of walnut production in the Taihang Mountains.
