土壤沿育化是人们关心的一个农田退化问题。 本文研究了鄱阳湖地区水稻土潜言化发生、分类及其肥力特性,对农田潜育化现状及发展趋势作了估价。从成土母质、水文环境、排灌工程及耕作制度等因素, 阐述了对水稻土沿育化的形成与发展关系。 强调稻一稻 肥换茬制, 并不是致治的主导耕作因素, 同时指出本区以次潜、 弱沿及上位潜育型为主, 并有所扩大, 从土壤生态前景看不可忽视。 提出了以“四沟…四改” 为主, 工程措施与生物措施相结合的改良技术对策.
Soil along the education is a people concerned about the degradation of farmland. This paper studied the occurrence, classification and fertility characteristics of paddy soil in Poyang Lake region, and evaluated the status quo and development trend of farmland gleization. From the factors such as soil parent material, hydrological environment, irrigation and drainage system and farming system, the relationship between the formation and development of paddy soil along the tillage is expounded. Emphasis on rice-stubble cropping system is not the dominant driving factor for the treatment. Meanwhile, the authors point out that the sub-submarine, weak-edge and upper latent type are dominant in this area and have been expanded, which can not be ignored from the perspective of soil ecological status. Proposed to “four ditch four changes” based engineering measures and biological measures to improve the combination of technical measures.
