Abstract
1985-1998年先后在黄土高原半干旱区的陕西吴旗、安塞县进行了沙棘优良品种引种选育试验研究。通过引种国内不同地理种源20余种优良沙棘类型,引进俄罗斯优良沙棘品种,采用家系选择法进行试验研究,初步筛选出生态经济型5种沙棘类型,经济型2种类型。前者生长迅速、树冠好、根系发达、郁闭快、水土保持效益好,且果实较大(果径0.8-0.9cm,百果重20-31g),单株产果量为2-3.5kg,Vc和含油量较高,其生态、经济性状较当地野生沙棘为好。此种类型沙棘适于在黄土丘陵大面积荒沟、荒坡种植。通过引种俄罗斯大果、无刺沙棘优良品种与本地野生中国沙棘对比分析看出,其适应性、抗性较中国沙棘差,经济性状较好。通过试验筛选出2种优良类型,果径为0.9-1.3cm、百果重46-52g,单株产果量2-3.5kg,无刺或少刺。此项研究为在半干旱黄土丘陵区大面积荒山、荒沟建造高产、优质沙棘林,高效、持续发展沙棘产业具重要意义。在引种试验中必须掌握好其关键技术,建立好采穗圃、种子园,并建立一定面积的集约经营的高产、优质沙棘园及良种繁育基地,掌握好抚育管理技术,特别是水、肥管理技
