Abstract
Salinization of farmland to grow corn for many years, using different proportions of organic and inorganic fertilizer, the determination of different soil physical and chemical properties and maize production. The results showed that the screening of these several Fertilizers proportion obtained for corn yield, soil improvement, organic and inorganic fertilizer ratio of: inorganic fertilizer(100 kg· hm-2of P2O5and K2O 70 kg· hm-2N 64 kg· hm-2), organic fertilizer(cattle manure 45 m3· hm-2); and inorganic fertilizer nitrogen content of nitrogen and organic fertilizer nitrogen(alkaline hydrolysis N) ratio of 2:3.
