Abstract: In order to test rice special formula fertilizer for rice to find the best fertilizing amount and proportion Ningxia gravity irrigation area, the rice field demonstration and field tests were carried on. The results showed that： the base fertilizer humic acid fertilizers （20-6-9） at 46.3kg/667m2, Topdressing Urea lOkg/667m2, 6kg/667m2 was fertilized respectively in the tillering stage and heading stage of rice, which not only meet the crop growth on nitrogen, phosphorus, potassium nutrient demand, but also reduce cost and increase benefit.
