Abstract

Abstract: In this paper， the characteristics， distribution and formation mechanism of cold waterlogged paddy were summarized in southern district， China. In order to promote the standardization of the improvement of cold waterlogged paddy field， new concept of cold waterlogged field， classification framework and its improvement technology based on plow pan distribution， geographical environment and soil type were put forward. The future research direction about cold waterlogged paddy field improvement and management under new classification framework was proposed.

Key words: cold waterlogged paddy, classification, paddy soil, improvement of mid\, low yield paddy
