摘要
概述了东北地区盐碱土形成的宏观机制和过程,并分析了盐碱土的危害及各种耕作的必要性。根据盐碱土的形成过程分析得出,在微观治理上,耕作是改良东北地区盐碱土理化性质的基础,也是化学改良和植物改良的基础,为盐碱土耕作及综合治理提供理论依据和指导。
The macroscopical mechanisms and processes of the formation of saline-sodic soil in Northeast China were reviewed.The disadvantage of saline-sodic soil and the necessity of all kinds of cultivation were analyzed.According to the forming processes of the saline-sodic soil,in microcosmic management cultivation was the basis of improving the physical and chemical properties of saline-sodic soil in Northeast China,and the basis of chemical amelioration and phytomelioration.It provided a theoretical foundation and guidance for comprehensive management to saline-sodic soil.
