摘　　要：以沙枣增殖试管苗为试验材料,对其进行生根培养研究,结果表明:最适宜生根培养基为1/2MS+NAA0.5 mg·L-1+蔗糖20.0 g·L-1+琼脂4.5 g·L-1,生根率可达95%,平均生根数为每株4.5条,最多可达每株6.1条,平均根长2.1 cm,最长根为3.5 cm。在4种试管苗移栽基质中,适宜移栽基质为腐叶土与炉灰混合物,其比例为2:1,移栽成活率为85%。The rooting cultivation research was carried by taking Elaeagnus angustifolia multiplication test-tube plantlet as experiment material. The result showed that the most appropriate root media was 1/2 MS ＋ NAA0. 5 mg · L-1＋ sucrose20. 0 g·L-1＋ agar4. 5 g·L-1. The rooting percentage was 95 %. The average rooting amount was 4. 5 per plant and the most was 6. 1. The average root length was 2. 1 cm and the longest was 3. 5 cm. The appropriate transplant medium was the mixture of leaf mould and stove ash. The proportion was 2： 1. The survival rate of transplanting was 85 %.
