Primary Study On Introduction Experiment Of Six Kinds Of Bush Coming From American Desert

For enriching the bush resource in the desert, the experiment introduced six species, total tweleve cultivars, from Utah, USA. They were breeded in the nursery. The results were as follows. (1) Before sowing, Kochia prostrate should be soaked, while Atriplex canescens and Atriplex tridentate should be stratificated; Kochia prostrate and Chrysothamnus nauseosus ssp. turbinatus should be planted in the later of Apr., while Ceratoides Ianata,Atriplex canescens , and Sarcobatus vermiculatus should be planted in the early of May. (2) Kochia prostrate and Atriplex canescens liked the sand soil, Ceratoides Ianata & Atriplex tridentate liked the fertile soil, but the check soil was the optimum to Sarcobatus vermiculatus and Chrysothamnus nauseosus ssp. turbinatus; Atriples canesceps ssp. gigante' biomass was remarkably higher than Caragana microphylla's. Caragana microphylla was the indigenous variety, (3) The experiment also found the ambient agents which effected the growth by the linear regression equation. (4) The sequence of drought-hardness ability was Kochia prostrate＜Sarcobatus vermiculatus＜ Atriplex canescens＜ Atriplex tridentate＜ Ceratoides Ianata＜ Chrysothamnus nauseosus ssp. turbinatus＜Caragana microphylla. The order of alkali-tolerance ability was Kochia prostrate＜ Ceratoides Ianata＜ Sarcobatus vermiculatus＜Atriplex canescens＝Atriplex tridentate＜Caragana microphylla. (5) The contents of six kinds of bush's crude-protein were higher than the corn's.
