Research on Optimization of Nitrogen,Phosphorus,and Potassium Fertilization Formula for Tomato Sweet Pepper
In order to study the optimal nitrogen,phosphorus,and potassium fertilization formula for tomato sweet pepper in Wolong District,Nanyang City,this paper used the response surface methodology(RSM)experimental design,which taked N fertilizer(N),P fertilizer(P2O5),and K fertilizer(K2O)as independent variables and tomato sweet pepper yield in the community as the response face value,and the 3-factor and 3-level RSM experimental design scheme is developed.The research results indicated that the fertilization formula for the highest yield of tomato sweet pepper per acre in the community is 20 kg of N fertilizer,6 kg of P fertilizer,and 23 kg of K fertilizer.Compared with the experimental control group,the yield increased by 43.16%.This experiment can significantly improve the yield of tomato sweet pepper and provided certain reference value for similar experiments.
