白滨藜生物学特性及饲用价值的初步调查与试验研究

Initially Investigate and Experiment on Biological Characteristic and Feed Use Value of Atriplex cana

对野生白滨藜进一步调查和进行人工种植试验,以更进一步地了解、挽救和充分利用白滨藜资源。调查结果表明:白滨藜是各类家畜晚秋及冬季所喜食的优良饲用植物,它具有抗旱、抗寒、耐盐、耐牧等优良特性,在我国西北地区开发利用前景广阔。人工种植试验结果表明:白滨藜旱作条件下最佳播种期为临冬(11月),种子出苗率达53.6%;其次为早春(3月下旬),种子出苗率达34.6%;其他时间播种均难以出苗,出苗率仅2.7%。

Atriplex cana C. A. Mey is a half shrub in the Chenopodiaceae Family. This half shrub is an important forage resource in the semiarid areas of northwestern in China. Livestock graze this nutritious forage during late-autumn and winter. Investigations and experiments were conducted in the laboratory, on natural rangeLands, and at cultivated sites without irrigation. Results of these various studies showed that Atriplex cana was resistant to drought,cold ,salinity,and grazing. The best time for pLanting Atriplex carla is Late-autumn and early spring. Prior to planting,The results of this study hopefully will encourage additional investigations of Atriplex cana and its use as forage and in protecting the environment.
