两种盐生植物在南北疆地区的适生性及吸盐能力

为了摸清盐生植物在南北疆改良盐碱地的实际应用效果,更好地利用盐碱植物,在南北疆地区进行田间试验,研究了两种盐生植物在新疆南北疆盐碱地的适应性及吸盐能力。结果表明,盐生植物在南疆的成活率明显高于北疆;而盐地碱蓬成活率明显要高于海篷子;北疆种植的盐生植物其植物体内的总含盐量明显高于南疆种植的盐生植物,其中盐地碱蓬高出约55%,海篷子高出约46%。由此可以看出,盐地碱蓬和海篷子更适合于南疆地区生长,而在北疆环境两种盐生植物吸盐能力均强于南疆环境,海蓬子吸盐能力明显强于盐地碱蓬。

The adaptability and salt absorption ability of two kinds of halophyte in southern and northern of Xinjiang

In order to investigate the application effect of the halophyte on salty soil improvement,two kinds of halophyte,including Suaeda salsa and Salicornia,were selected and field experiments on the adaptability and salt absorption ability of them were carried out in both southern and northern of Xinjiang.The results showed that the survival rate of the two kinds of Halophytes in the southern Xinjiang was significantly higher than that in the northern Xinjiang,and the survival rate of Suaeda salsa was higher than Salicornia.The total salinity content of halophytes planted in the northern region was obviously higher than that of halophytes planted in the southern region,which was about 55％ and 46％ higher than for Suaeda salsa and Salicornia,respectively.It was concluded that Suaeda salsa and Salicomia were more suitable for growth in the southern region.Two types of halophytes salt absorption abilities in northern region were stronger than those of the southern region;the absorption ability of Salicornia was higher than Suaeda salsa.
