沙生冰草于1982年从加拿大阿尔伯塔省引种到黑龙江省,裁培结果证明,对我省中、西部地区环境条件有良好的适应性。它原产于东俄、西伯利亚西部、中亚寒冷干旱平原。1911年从西伯利亚西部引种到加拿大萨斯喀切温大学,1927年在加拿大推广种植。沙生冰草有两种类型:二倍体(2n=14)型或扁穗型[Agropyron cristatum (L.)Gaertn.]和四倍体型(2n=28)或标准型[Agropyron desertorum(Fisch.exlink)Schult.]。二倍体型比四倍体型的种子小、株体矮、茎细。二倍体型的寿命长,而四倍体型在严重干旱条件下比二倍体型的保绿性强。生态习性沙生冰草是寿命特别长的疏丛型禾草。1928年在加拿大农业研究
Sarshengcao grass was introduced into Heilongjiang Province from Alberta, Canada in 1982, and the results of its cutting and cultivation proved that it has a good adaptability to the environmental conditions in the middle and western regions of our province. It is native to eastern Russia, western Siberia, cold and dry plains in Central Asia. 1911 introduced from western Siberia to Canada Saskatchewan University, in 1927 to promote planting in Canada. There are two types of Spartina alterniflora: Agropyron cristatum (L.) Gaertn. And tetraploid (2n = 28) or standard [Agropyron desertorum (Fisch. exlink) Schult.]. Diploid than tetraploid seeds, plant short, thin stem. Diploid type has a long life span, while tetraploid type is more green-protective than diploid type under severe drought conditions. Ecological habits Sarcandra grass is a very long life sparse Cong grass. 1928 Agricultural Research in Canada
