4种国外禾草引种试验研究

Introduction Test of Four Exotic Grasses

通过国外4种禾草材料在内蒙古太仆寺旗的引种试验表明:4种国外禾草在生长季均未发现病株现象,具有很强的耐旱、抗寒性,在本试验区均能安全越冬,且生长良好,适合我国北方干旱及半干旱地区种植,是干燥寒冷地区的优良禾草,值得推广应用。

An introduction test of four exotic grasses （Agropyron desertorum; Agropyron trachycaulum; Elymus dahuricus; Bromus inermis） was carried out in TaiPuSiQi, Inner Mongolia. During the growing season, the phenomenon of plant disease was not observed for these grasses, and they showed strong drought and cold resistance. It was also found that all of them survived safely in winter and grow quite well. It can be concluded that they are suitable for the cultivation in arid and semiarid area of northern China, especially in the dry and cold area, thus they are worthy of popularization and application.
