利用盐生植物发展“盐湖农业”研究进展

Research Progress of Using Halophytes to Develop“Salt Lake Agriculture”

由于人口增长和全球气候变暖,次生土壤盐碱化日趋严重,淡水资源缺乏,使得人类粮食和食品供给面临严峻挑战。“盐湖农业”为解决这一问题提供了一种新的思路。本文评述了盐生植物在农业上的应用国内外研究进展,重点综述了盐生植物作为食物、饲料、工业原料等方面的研究。盐生植物生长环境比较恶劣,一些盐生植物为应对逆境环境而合成出丰富的次生代谢物,这些代谢物对预防疾病和促进健康大有益处,因此近年来市场对盐生植物的需求显著增加。我国盐湖资源丰富,利用盐生植物发展盐湖农业有得天独厚的条件,具有广阔的应用前景,本文最后提出了在我国发展盐湖农业的几点建议。

Global food supply faces major challenges due to population growth,global warming,secondary salinization of soils,and scarcity of freshwater resources.“Salt lake agriculture”offers a novel solution to this problem by using salt tolerant plants and animals and saline water to develop agriculture.This article reviews the research progress on halophytes in agriculture,focusing on halophytes as food,feed,and industrial raw materials.As halophytes contain high amounts of health-promoting secondary metabolites,new market demand for such crops has emerged.Salt lakes are abundant in China,and making the development of salt lake agriculture using salt-tolerant crops favorable.Based on the characteristics of China’s salt lake and saltwater resources,proposals for the development of salt lake agriculture have been put forward.
