在塑料大棚内人工控制喷雾条件下，利用良种沙棘、优良单株的结果母树和２年生绿枝苗上的１年生半木质化枝条作插穗，进行扦插试验。其结果表明，７月中旬，剪取２年生绿枝扦插苗的枝条，剪穗１２ｃｍ，经５０ｍｇ／ｌＩＢＡ处理１２～１４小时，在河沙基质上扦插，生根率达９４．２％，增加了插穗数，加快了良种沙棘的扩繁 In artificial plastic shed control spray conditions, the use of elite seabuckthorn, the results of good single tree and two-year-old green branches on the seedlings of semi-lignified branches for cuttings, cutting test. The results showed that in mid-July, branches of 2-year-old green shoot cuttings were cut and cut at 12 cm. After 50 mg / l IBA treatment for 12 to 14 hours, rooting rate reached 94.2% Cuttings speed up the expansion of seed seabuckthorn
