摘要
在易涝易渍地区雨季,涝渍相伴相随,对作物影响很大,研究涝渍连续过程作物排水控制指标具有重要生产意义。根据这类地区涝渍发生特点,以棉花涝渍相随试验为基础,建立了作物排水分析基本模型,依据模型提出了涝、渍连续过程排水控制指标的确定方法。从涝、溃连续过程的统一体中确定适宜的排涝、排渍指标与传统的从涝、渍分别试验确定排涝、排渍指标有很大不同,它符合涝渍地域生产实际,体现了涝渍兼治的排水控制新理念。
In the regions vulnerable to flooding and subsurface waterlogging in rainy seasons, surface and subsurface waterlogging is often accompanied each other, which greatly influences upon the crops. It is important in production to study the dominated quota of drainage under conditions of continuous surface and subsurface waterlogging. According to of the occurrence of surface and subsurface waterlogging in this regions, drainage model was established, and the method to determine the drainage dominated quota under such an continuious conditions was presented. These drainage dominated quota determined under such an continuious conditions are very different from those determined under traditional individual inundation experiments and subsurface waterlogging experiments, This method can reflected the reality in this region and provided a new concept of drainage control.
