The trials on cultivation of Atriplex canescensconducted in Minqin Desert Control Experiment Station reveals that this speciesentails fine qualities as strong tolerance in drought, cold, salinity and low temperatureas well as high annual biomass. So it cab be extended in sandy areas with favorableirrigation condition, and on hilly in loess plateau with relatively high rainfall and lowevaporation. As a new substitute species for water/soil conservation and rangelandregeneration, it has a big potential to be extended. However, more research on withinwhich scope this species can be extended need to be done

The results are as follows: 1 The ingroups studied are divided into four clades on the molecular phylogenetic trees that we reconstructed.
我们测定了斑腿蝗科10亚科20种蝗虫和其它蝗科3种蝗虫的16S rDNA序列片段,并从GenBank中下载了斑腿蝗科3种、其它蝗科10种及蚱总科2种的16S rDNA相应序列片段,然后对这共计38种蝗亚目昆虫的16S rDNA序列片段进行了同源性比较,以其中2种蚱作外群构建了蝗总科的分子系统树,得到的结论如下:1斑腿蝗科并非是一单系群。2该科中的切翅蝗亚科、稻蝗亚科、黑蝗亚科、秃蝗亚科、卵翅蝗亚科、蔗蝗亚科均不是单系群,分子系统树的聚类结果与基于形态特征的斑腿蝗科的分类体系有较大的出入。3支持将黑蝗亚科和秃蝗亚科合并为一个亚科——秃蝗亚科。4卵翅蝗、伪稻蝗和稻蝗三者有很近的亲缘关系。
