涝渍盐碱灾害是我国不少地区农业生产发展的主要障碍,提高防御涝渍盐碱灾害的能力,对加速发展农业生产有着重要的现实意义和战略意义。长期的实践证明,农田排水在防御涝渍灾害和土壤盐碱化、改善田间耕作管理、增加农作物产量、促进国民经济发展等方面起着积极的作用。阐述了农田排水技术的重要性,回顾了排水技术的发展与主要实践,指出排水领域存在的问题和差距,结合我国国情,提出今后农田排水领域的研究发展方向。
The waterlogging, high water table and saline-alkaline disasters are the main constraint iactors of agricultural production in many regions in China. The increase of controlling capability of waterlogging and saline-alkali has a significant meaning for speeding agricultural development. The long-term practices showed that the farmland drainage could control waterlogging and saline-alkaline disasters, ameliorate the farming cultivation, enhance the agricultural productivity and promote national economic development. This paper describes the importance of farmland drainage technology, reviews the advancement and practices of drainage technology, points the available problems and major difference between china and world. Combining China＇s conditions, the study trends of drainage field in the future are proposed.
