摘 要：
In this study,ditching is adopted to drain off excessive water in farming soil in wetland.After ditching,the process of draining off is accelerated,underground water level is lowed,soil permeability is improved,soil nutrients are enriched,the growth and devel- opment of rice plant is also promoted and the grain yield is raised.The integral function of ditching to draining off excessive water is fully developed.
