在沙棘(Hippophae rhamnoidesLinn)休眠期,以横径0.5～1.0厘米的1～2年生12～15厘术长枝条为试材,采用地膜覆盖法扦插,随即灌水,并盖草帘保湿遮荫,扦插后50天左右,每个插条产生2条以上的不定根并发芽,成活率达95.0％以上。试验结果表明,扦插成活率与生长素处理不存在正相关。雌性插条成活率较雄性为高。
In the dormant period of Hippophae rhamnoides Linn, 12 to 15 cm long shoots of 1 to 2 years old with a diameter of 0.5 to 1.0 cm were used as test materials, and cuttings were mulched with mulching method and then irrigated. After about 50 days, each cuttings produced more than two adventitious roots and sprouting, the survival rate of 95.0% or more. The results showed that there was no positive correlation between cutting survival and auxin treatment. Female ram survival rate is higher than the male.
