Study on Nitrogen,Phosphorus and Potassium Fertilizer Utilization Rate in Rice Crops of Sanya city
By applying fertilizers in a balanced manner,optimizing the fertilizer formulation,and understanding the efficiency of rice in utilizing nitrogen,phosphorus and potassium fertilizer,this study aims to provide scientific basis for the rational formulation of fertilizer program in Sanya City.The results showed that the yield of formula fertilization treatment was significantly higher than that of other treatments,and 131.73%,92.69%,10.11%and 16.12%were increased compared with no fertilization,nitrogen,phosphorus and potassium deficiency treatments.In addition,the nutrient utilization rates of N,P2O5 and K2O were 41.45%,27.07%and 52.29%under formula fertilization treatment.The results indicated that the fertilization formula had a significant effect on increasing rice yield and improving fertilizer utilization rate effectively.
