Abstract
The effects of fertilizer application depth on nitrogen utilization and yield of wheat in dry land have been studied by using soil column method. The results showed that with fertilizer applying in subsurface layer of 20～40cm more nitrogen absorbed was distributed in kernel and less in root system, the utilization ratio and recovery ratio of fertilizer nitrogen increased, the ramainder ratio in soil and loss ratio of fertilizer nitrogen decreased, and yield of wheat increased. However, when the fertilizer applied in surface layer of 0～20cm and deep layer of 60～80cm, the results were contrary. It is concluded that the depth of 20～40cm fertilizer application is the best for gainning higher yield and nitrogen fertilizer utilization efficiency in dry land wheat.
