半干旱黄土丘陵区沙棘优良品种引种栽培试验研究

1994-2003年在黄土高原半干旱区的陕西吴旗县、安塞县进行中国沙棘优良类型和俄罗斯优良沙棘品种引种试验,采用家系选择法初步筛选出5个中国沙棘生态经济型优良单株,对3个俄罗斯良种沙棘的生长适应性经济性状进行了评价。前者生长迅速、树冠好、根系发达、郁闭快、水土保持效益好,果实较大、单株产量较高、Vc和含油量较高,适于在黄土丘陵区种植;后者经济性状较好,果实大、无刺或少刺,但适应性较中国沙棘差。

Study on Introduction and Cultivation of Seabuckthorn Variety in the Semiarid Loess Hilly Region

The study on introduction and cultivation of seabuckthorn was conducted in the loess semi-arid region at Ansai and Wuqi county Shaanxi Province in 1994-2003. 5 Chinese seabuckthorn varities with good eco-economical form and 3 elite individual Russia seabucktorn varities selected by family method were evaluated to their properties of ecology and economy. The Chinese one has characters of fast growth, quick canopy density, fine crown, developed roots, fine benefit of soil and water conser-vation, and bigger fruit, yield of individual plant, higher Vc and oil content. It is fit to plant in loess hilly-region. The Russian one has better economical properties with big fruit and less thorn. But its adaptability is poorer than that of the Chinese one.
