In order to solve the problems of unreasonable fertilization in saline alkali area,this paper took ZD958 and DY18 as the study material and studied the effect of different organic fertilizer on nutrition concentration of corn,nutrient distribution and producing each unit seeds harvest the nutrient component by field trial. The results showed that： Using organic fertilizers achieved a high and stable yield level,as the different organic fertilizers applicate on different corn varieties; we could conclude that the treatment of chicken manure for stable yield was better than other treatments. Different fertilizers on two kinds of corn varieties had effect on seeds of N,P and K concentration,they all performed as chicken manure 〉green and blue creatures under phosphorus 〉bio-fertilizer 〉under phosphorus in microorganisms 〉the contrast; The nutrient concentration was different in corn varieties of straw,of which chicken manure was the best and green and blue creatures under phosphorus was the second. In the grain and straw the distribution ratio of nitrogen and phosphorus content had good correlation with corn yield,but it＇s not obvious in potassium; the better corn grown,the more N,P and K were consumed to form economic yield per unit. All these illustrated that the use of corn to nitrogen,phosphorus and potassium had luxury absorption on some degree.
