Abstract


Atyipiex canexcen(sPursh)Nutt.and Hippophae rhamnoides Linn. are two shrub species introduced of important value of ecology construction, water conservation, salt and alkali terra changing, woody feed production in relatively rough climate area of China. In order to develop the scale propagation technique of these two plants, effects of cottage collection, plant growth regulator treatment, root induction and plantlet acclimation were studies with softwood cutting of these two plants under the condition of full sunlight and automatic water spraying at Gansu Jingchuan agriculture hi-tech demonstration area in the year of 2004.1.Roots emerged without callus generation from the bark of these two plants. The duration of root formation is much shorter(4-7 days).2. Treatments with certain concentrations of plant growth regulator could significantly stimulate the rooting percent. The rooting percent, of Atyipiex canexcens cottage could reach 93.6%, 17.30% higher than that of the control, dipped with 100 mg/L NAA; of Hippophae rhamnoides could reach 98.8%, 25.73% higher than that of control, dipped with 100 mg/L IBA.3. Differences existed within three Atyipiex canexcens varieties. The rooting percent of variety“Jianxiong 1”is 93.3%, 5.978% higher than that of“Wulanshalin”.4. The optimum period of cutting propagation of the two plants is in early June till early September under the condition of full sunlight and automatic water spraying at eastern Gansu province. 150 thousand of these plants of three batches could be produced in one year through this systematic technique.
