摘要
根据在鲁北地区开展的几种主要粮食作物耐渍涝的大田调查和筒栽试验，通过对地表水、地下水和土壤水的动态观测，分析土壤通气率对作物生态的影响，。而提出了玉米、大豆、高粱、谷子不同生育期的耐涝和耐渍的控制标准极限及其高水位允许的持续时间，可为同类地区规划在田排水工程提供设计参数和科学依据。
The standard limitations of subsurface waterlogging control and tolerance duration of high water level in different growing stages of corn, sorybean,sor hum and millet have been presented based on field investigation and plot experiment of subsurface waterlogging control of main food crops produced in the North region of Sandong Province and dynamic measuring of surface water groundwater and soil moisture and analysis of soil aeration rate effect to crop growing status. The standards can be used for planning of irrigation and drainage projects in different regions.
