Title: Effects of N,P and K Fertilizer Application on Wheat Yield in Jiangsu Coastland
Abstract: [Objective]The research aimed to identify the effect of N,P and K fertilizer on wheat yield in Jiangsu coastal area,then develop a fertilizer formula which was adequate for the specific soil types and wheat cropping system in Jiangsu coastal area.[Method] Take the spring wheat young wheat 18 which was planted in large area in Jiangsu as the test materials,and through field experiment and laboratory analysis,the regulating effect of different ratio of nitrogen fertilizer,phosphorus fertilizer and potash fertilizer on dry matter accumulation,yield and quality was studied.[Result]All levels of nitrogen fertilizer,phosphorus fertilizer and potash fertilizer played a significant regulatory role.In this experiment,the yield of treatment⑥(N 2 P 2 K 2) was the highest.The second was treatment⑦(N 2 P 3 K 2).The lowest was treatment①.Nitrogen stimulation effect was the most obvious in the three nutrient elements nitrogen,phosphorus and potassium that could promote wheat growth and the development.But wheat production decreased when nitrogen content was above a certain level.The yield of treatment N 3 P 2 K 2 was lower than that of treatment N 2 P 2 K 2 by 498 kg / hm2.The phosphorus effect on wheat yield also showed the same trend.[Conclusion]Treatment N2P2K2 can satisfy the demand for fertilizer,and its normal growth enhance photosynthetic characteristics of plants,and increase the strength of grouting.
