摘要
晋龙12、、3号核桃优良品种1999年在黄土高原丘陵区华亭县引种栽培,经过6a的试验观察,其生长健壮、发育良好,晋龙3号单位投影面积产量最高为128.7g/m2,晋龙2号稍差。丰产性状综合指数以晋龙3号最高,三个优良品种经济性状,超过国家一级标准,一些指标达到国家优级标准。6a的试验证明晋龙1、2、3号适宜在黄土高原丘陵区大力推广和发展。
The fineness species of Juglans regia Jinglong 1,2,3 were introduced in the hill area of Loess Plateau of Huating county in 1999. Nased on the introduction experiment of six years, the results showed that they have grown stronger and are well-developed, and the Jinglong 3 was the highest high-yield in unit projection area in 128.7 kg/m^2, and the Jinglong 2 was lower. The highest high-yield character synthetic index was the Jinglong 3. All of the fineness species＇ economic characters beyond the state first standard, and some index reached the excellent standard.The Jinglong 1,2,3 ar all suited for development in the hill area of Loess Plateau.
