摘要
本文研究了四湖地区水稻土潜育化的发生、类型及其肥力特性,对该区潜育化现状及发展趋势作了评估。阐述了地貌、水文环境、水利工程及耕作制度等因素与水稻土潜育化的形成和发展的关系。根据该区潜育化现状和发展趋势,本文提出了对潜育性水稻土实行“全面规划、综合治理”的总原则,并认为应实行宏观治理与微观改造相结合、工程措施与生态措施相结合、改良与利用相结合等对策和措施。
This paper presents the gleization genesis, the gleization types and their fertilizer characteristics of paddy soil in Sihu region; estimates the status quo and evolution trend of the gieization; and expounds the relationship of the formation and development of paddy soil gleization with landform, hydrological environment, irrigation projects and cropping systems, Based on the status and trend of the gleization, the paper suggests that, the overall planning and comprehensive control be a general principal for ameliorating the gleization paddy soil in the region; and some concrete strategy and measures, including to combine macroscopic control with microcosmic transformation, engineering measures with ecological measures, amelioration with utilization, etc., be carried out.
