钠和其他离子对钾离子替代作用的研究进展

Review on the replacement of potassium by sodium or other ions

为缓解钾素资源紧张的问题,不少学者提出了利用Na+等离子对K+的替代作用来解决。围绕K+、Na+在植物体内的生理功能、钾钠替代的生理效应以及存在的问题,着重阐述了钠对钾的替代作用;另外,还综述了K+与NH4+、Ca2+、Mg2+间的互作关系等。

For alleviate the problem of the shortage of potassium, many scholars put forward to the replacement of potassium by sodium or other ions. This paper focus on physiological function of K ＋ and Na＋ in plant, physiological effect of potassium-sodium substitution and the existing problems, emphatically expounds the replacement of potassium by sodium. In addi- tion, this paper also review the interactions between K ＋ with NH4 ＋ , Ca2 ＋ , Mg2 ＋ etc.
