Influence of Different Fertilizer Processing on the Yield of Rice and Its Yield Components
To explore suitable application of nitrogen and phosphate fertilizer in rice production and methods of increasing absorption and use efficiency of N and P in rice plants, the experiment of nitrogen and phosphate levels was conducted in Bishan of Chongqing. The results showed that there was a parabola relationship between rice yield and the application rate of N, P fertilizer; The effect of soil/plant conditioner was remarkable in increasing absorption and use efficiency of N and P in rice plants. Under this experiment condition, the high yield was obtained in treatments which amounts of fertilizers and soil/plant conditioner application were as follows: 5.9 kg/667 m2 of nitrogen, 4.1 kg/667 m2 of phosphate, 5 kg/667 m2 of potassium and 33 kg/667 mE of soil/plant conditioner. Rational fertilization and application of soil/plant conditioner could obtained the high yield in rice varieties which great demand for nitrogen and phosphate fertilizer.
