Effects of Different Amounts of Nitrogen Phosphorus and Potassium Fertilizer on the Growth Rate and Yield of Maize
Taking Denghailiangyu No.99 maize as the research object,the L9(33)orthogonal experiment was used to design the collo-cation ratio of 12 kinds of N P K fertilizer,and the effects of different amounts of N P K fertilizer on the growth rate and yield of maize were studied.It was found that the most suitable nitrogen,phosphorus and potassium fertilizer application rate for the maize of Denghailiangyu No.99 was m(carbamide)∶m(P2O5)∶m(K2O)=10∶8∶5.The effect of nitrogen fertilizer on the growth rate and yield of maize was higher than that of other two fertilizers.
