黄河三角洲盐渍土综合治理与开发研究

COMPREHENSIVE HARNESS AND EXPLOITATION OF SALINE SOIL IN THE YELLOW RIVER DELTA

黄河三角洲土地资源的开发利用必须以灌溉排盐为主,实行沟、渠、路、林、田配套,从农、林、牧各业的实际出发,因地制宜地推广地膜棉、合理扩种水稻,适当发展林、牧业,维护生态平衡。实行统一管理,科学指导,使该区的整个开发利用过程,不仅是一个土壤脱盐过程,也是培肥和改善土壤理化性质,提高土地生产力的过程。

The results of study showed that the main strategy of exploiting and usilizing land re- source in the Yellow River Delta must be put on irrigation and desalinization.In considera- tion of the actual situation of faming,forestry and animal husbandry,we must reasonally expand rice area,popularize cotton cultivation with plastic film mulching,develop forest and animal husbandy in the light of local conditions,defend ecological balance and carry out comprehensive harness,to make the whole exploitation process not only a desalinization process but also a soil improving and fertilizing process,thus increasing land productivity.
