摘要
采用电导法对扁艹蓄、白杨、苋菜、马尾松、扁扁草、麻黄、苦豆子、红柳、灰藜和四翅滨藜共10种地被植物的抗寒力进行了研究,其中前九种植物来自新疆寒冷地区。通过对低温处理后的各试验材料电解质的电导率进行分析,结果表明:四翅滨藜抗寒性最强,苋菜抗寒性最弱。10种试验材料抗寒性强弱顺序依次为:四翅滨藜>灰藜>白杨>红柳>麻黄>苦豆子>马尾松>扁扁草>扁艹蓄>苋菜,以上列举的前7种植物在新疆地区可自然越冬,其余3种植物则需采取必要的越冬防护措施[1]。
The cold resistance of 10 kinds of cover plants was investigated, such as Gentianopsis barbara ( Froel. ) Ms, white poplar, Amaranthus tricolor, masson pine, Echinochloa crusgalli ( L. ) Beauv., mahuang , Sophora alopecuroides L. ,rose willow,oak- leaved gcosefeet, Atriplex canescens,the nine kinds of which came from the cold area. The electrical conductivity of electrolyte of tested materials treated by low temperature was analyzed. The results indicated that the cold resistance of Atriplex canescens was the strongest, that of Amaranthas tricolor was the weakest. The orderof cold resistance of the tested materials was Atrplex canescens 〉 Grey canescens 〉 white popular 〉 rose willow 〉 mahuang 〉 Sophora alopecuroides L. 〉 masson pine 〉 Echinochloa crusgalli ( L. ) Beauv. 〉 Gentianopsis barbata ( Froel. ) Ma 〉 Amaranthus tricolor. The first seven species quoted above could overwinter naturally in Xinjiang. The other three kinds of the species could not overwinter without any effective protection.
