【 摘 要 】

Scientific fertilization is the key to obtain a high-yield and good quality rice. In order to understand the present situation of rice fertilizer application in the Plain Area of Hanzhong Basin, a survey had been conducted. The investigation results showed that: in the Plain Area of Hanzhong Basin, N application was more higher, P2O5 application was reasonable and K2O application was a little lower. Fertilization was very unbalanced and the application rates were quite different among farmers. The base to dressing ratio was unreasonable. All the P2O5, K2O and most of N were applied as base fertilizer, and only a few farmers use top dressing N fertilizer. In the frame of fertilizer variety, there is a phenomenon that using more ammonium bicarbonate than formula fertilizer, using more chemical fertilizer than organic fertilizer and using more macro element fertilizer than trace fertilizer.
