Abstract
Sandy soil in the irrigation area of Ningxia are experimentally studied with the influence of different nitrogen fertilizer on waxy maize growth and yield,the results show that: on the basis of applying P2O5 10 kg/ 667 m2 and K2O 8 kg/ 667 m2,waxy maize yield increased with the increase of nitrogen fertilizer,when nitrogen application rate reaches a certain amount,production no longer increases with the increase of nitrogen application,with 30 kg / 667 m2 advisable,waxy maize to obtain the maximum yield of 645.93 kg / 667 m2. So nitrogen fertilizer in 30 kg/ 667 m2 around,proper fertilization measures(appropriate depth,and combined with water,and optimum fertilization) can meet the needs of waxy maize for nitrogen,a higher yield.关键词
