摘要
盐渍化土壤在世界上分布广泛,在我国也有很大的面积。为了开发利用盐渍化的土地资源,传统的治理途径是采用工程和农业措施相结合的方法。然而,近年来越来越多的研究表明,发掘利用现有的生物资源,应用现代生物技术,通过培育抗盐品种来提高植物抗盐性也是开发利用盐碱土的一个重要方面。本文通过对作物耐盐品种和盐敏感品种的比较,综述了盐胁迫下粮食、果树、蔬菜及棉花等作物对K+、Na+、Ca2+、Mg2+等离子吸收及分配的影响,并提出了进一步的研究方向。
Saline soil are widely distributed in the world,there is also a large area of it in our country.In order to develop and use the saline land resources,the traditional govermance way is through the method of combing the use of engineering and agricultural practices.However,in recent years an increasing number of studies have shown that cultivating salt-tolerant varieties by exploring the use of exiting biological resources,applying modern biotechnology to improve the salt resistance of plant is also an important aspect to develop and use saline-alkali soil.This paper reviewed the effects of absorption and transportation on ions such as K＋,Na＋,Ca2＋,Mg2＋ in grain crops,fruit trees,vegetables,cotton and so on under NaCl stress by the comparison of salt-tolerant species and salt-sensitive varieties.
