Influence of Water Volume on Soil Water and Nitrogen Transport and Distribution Characteristic under Facilities Condition
Abstract：Through the facilities imitating experiment of film hole irrigation with nitric acid potassium solution under different water volumes,the content of soil water and nitric nitrogen was determined and analyzed in the different times after irrigation.The results showed: the contents of soil water and nitric nitrogen under different water volume reduced with time and achieved the maximum at the center while it was reverse away from film hole;soil water content decreased with the increase of water volume at the same position while the nitric nitrogen content was opposite.The influence of the increase of water volume on soil water and nitric nitrogen distribution was good for plant to absorb water and nitric nitrogen.
