Effects of Slow Release Agents on the Growth and Yield of Maize
Field experiments were conducted in Tongzi County,using Lin'ao No.1 maize variety as experimental material,including conventional fertilization,20%reduction of nitrogen fertilizer,20%reduction of nitrogen fertilizer combined with DCD,20%reduc-tion of nitrogen fertilizer combined with DMPP,20%reduction of nitrogen fertilizer combined with CP.The growth,development,yield and quality of maize under different treatments were compared.The results showed that the combined application of three slow-release agents could promote the growth and development of maize,increase the yield and improve the quality of maize,among which DCD and DMPP had the best effect,and the yield and quality of maize could even exceed the conventional fertilization level.
