【摘要】：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。
[Abstract]:In order to find out the practical application effect of salt plants in the saline alkali land of northern and southern Xinjiang, the adaptability and salt absorption capacity of two salt plants in North and South Xinjiang saline alkali land in Xinjiang were studied in the north and South Xinjiang. The results showed that the survival rate of salt plants in Southern Xinjiang was obviously higher than that in Northern Xinjiang; and the salt base was in the northern Xinjiang. The survival rate is obviously higher than that of the sea tarpaulin; the salt content in the plants of the North Xinjiang is obviously higher than that of the salt plants in the southern Xinjiang, of which about 55% of the salt and the sea tarpaulin are higher than 46%., thus it can be seen that the alkali salt and the sea tarpaulin are more suitable for the growth of the southern Xinjiang, and two kinds of salt plants in the northern Xinjiang environment. The ability of salt absorption was stronger than that of Southern Xinjiang. Salicornia had stronger salt absorption ability than Suaeda salsa.
