Preliminary Study on Introduction of Walnut at Nang County of Tibet

对核桃品种"薄壳香"和"晋龙1号"在西藏郎县进行引种试验研究,统计分析了在不同土壤、环境条件以及不同时间定植后核桃的成活率及树体生长与结果情况。结果表明:在农家院及农田间作核桃成活率远远高于经客土后的开荒地定植,而且引种的苗木第1年在苗圃假植,第2年选择土质、气候条件好的园子进行定植,不仅成活率高,而且树体生长健壮,同时比当地品种早产、丰产,这是核桃引种至西藏朗县成功的关键所在。

This article to Shanxi＇s shell fragrance with Jin dragon 1 conducted the research in Tibet Lang Xian introduction experiment, the statistical analysis after the different soil, the environmental condition as well as the different time field planting the walnut survival rate, the tree body growth and the result situation. The result indicated that in the agricultural courtyard and the farmland interplanting walnut survival rate was higher than by far after the imported soil opens up wasteland the field planting, moreover introduced a fine variety the nursery stock first year in the plant nursery bedding in earth;the second year choice soil texture, the climatic conditions good garden carried on the field planting.
