【目的】引进欧洲珍稀观赏果树抗寒红叶李优良品种,筛选出适应新疆栽培的观赏果树红叶李抗寒良种,改善我国高寒区彩叶观赏果树品种单一的现状,丰富新疆林果种质资源及品种多样性。【方法】引进少量欧洲抗寒红叶李优良品种,嫁接保存种源,进行生物学、生态学特性观测,适宜砧木、扩繁试验研究,适应性、抗逆性、栽培观赏性中试。【结果】抗寒红叶李集观花、观果、观叶、鲜食于一身;叶片富于变色,果实美味可口,幼果紫红色,成熟后果实亮红色,果肉鲜红色;耐寒、耐旱、耐瘠薄,在-36℃左右的低温环境下能良好越冬,是优良的绿化观赏果树。【结论】通过5 a的试验研究、中试推广,选育的抗寒红叶李在新疆表现出了良好的生长状况,是我国尤其是高寒区域栽植难得的优良观赏果树,2009年通过新疆林木良种委员会审认定,命名为西域红叶李。
【Objective】 The objective of this study was to introduce fine varieties of rare ornamental red leaves of rare ornamental fruit trees in Europe and screen out cold-resistant varieties of ornamental fruit trees such as ornamental fruit trees, Hongye Li, which are cultivated in Xinjiang, to improve the status quo of single ornamental fruit trees of ornamental fruit trees in the alpine region of China and to enrich germplasm resources and species diversity Sex. 【Method】 A small number of fine varieties of cold-resistant Korean red leaf Lee were introduced and their provenances were grafted. The biological and ecological characteristics were observed, suitable for rootstocks, propagation experiments, adaptability, stress resistance and cultivation ornamental test. 【Result】 The results showed that the cold-resistant leaves of red-leafed plants had a concentration of flowers, fruits and foliage, and fresh food in one. The leaves were rich in discoloration, the fruits were tasty and delicious, the fruit was bright red and the fruits were bright red, , Resistant to infertility, good winter at -36 ℃ low temperature environment, is an excellent green ornamental fruit trees. 【Conclusion】 The 5-year experimental study showed that cold-resistant leaves of P. euphratica, which had been popularized in the pilot plant test, showed a good growth condition in Xinjiang. It was a rare and excellent ornamental fruit tree planted in China especially in the alpine region. In 2009, The Committee found that the trial, named the red leaves of the Western Regions.
