摘要
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。
Adaptability of 12 new walnut cultivars to the Taihang mountain regions was studied in the experiment, which were selected lately in China and were planted or topgrafted in orchards in Heshun County, Yushe County and Zuoquan County which are located in Taihang mountain regions. From 1991 to 1997, experiment contained nut qualities, high-yield abilities and adaptation to the climate in the Taihang mountain areas. The results were showed as follows: Six cultivars (Zhonglin No.3; Baofeng; baokexiang; Liaoning No.l; Jinlong No.1; Jinlong No.2) were resistant to coldness, arid soil and diseases, which were widely cultivated at elevation of 1 000-meter or below in the Taihang mountain. Arid soil could be improved through adding of manure and laying. The keys of walnut production were to preserve moisture and fertility in the soil and to do a rational fruit set.
