关键词: 夏玉米, 氮肥, 磷肥, 经济施肥

Abstract: The orthogonal multinomial regression design containing 2 factors,4 levels andsquar root model was used to study the economic application amount of N and P ferilizer forsummer maize with different yield levels.Results showed that the economic applicationamounts of N fertilizer respectively,and that of for summer maize with high,middle and low yield.

Key words: Summer maize, Netrogen, Phosphorus, Economic fertilizer application
