Abstract
The results of analysis are as the following. The irrigation - optimized fertilization and irrigation - optimized fertilization with crop residues significantly make total root amount of winter wheat more than traditional irrigation fertilization. The root length density and root weight density decrease slowly according to soil depth, and the efficiency of nitrogen fertilization using increase significandy. The efficiency of water using in each treatment is insig-nificandy different.
