【摘要】 我国盐碱地面积大，分布广，盐碱地由于含有大量盐离子不适合普通作物的生长.如何开发和利用好这些盐渍化土地对于解决我国的粮食和资源短缺问题至关重要.冰叶日中花是一种既耐干旱又耐盐碱的盐生植物，兼具食用价值和生态价值，在拓展盐渍化土地方面有很大的潜力.本文综述了冰叶日中花的耐盐机理并展望了其在盐碱地上的应用前景.更多还原

【Abstract】 Saline-alkali land in China has a large area and widely distributed. Saline-alkali land is not suitable for the growth of common crops because of its large amount of salt ions. It is very important to develop and make good use of these salinized lands in order to solve the shortage of food and resources in China. As a kind of halophyte, Mesembryanthemum crystallinum L. is tolerant to drought and salinity and has both edible value and ecological value.Therefore, it has great potential in expanding salinized land. In this paper, the salt tolerance mechanisms of M.crystallinum are reviewed and its application in saline-alkali land was prospected.更多还原
