Taking maize of“Xianyu 1225”as the tested variety，and appling no organic fertilizer(conventional fertilizer)as CK，three types of organic fertilizers including bio -organic fertilizer(M1)，sheep manure organic fertilizer(M2)and cow manure organic fertilizer(M3)，and 4 organic fertilizers rates3，6，9，12 t/hm² were applied in this study to explore the reasonable amount of different organic fertilizer types in the area. The results showed that the application of bio-organic fertilizer had the most significant effect on soil physical properties compared withCK，especially the application of bio-organic fertilizer of 6 t/hm². The soilporosity，saturated water content and field water holding capacity increased by 24.96%，26.47%，66.01%，respectively，compared with CK soil bulk density decreased by 10.74%. All three organicfertilizers increased soil nutrientcontent，but the improvement effect was not significant. Sheep manure organic fertilizer could significantly improve the agronomic traits of corn and improve the quality of corn products. When low-level cow manureorganic fertilizer(3 t/hm²)wasapplied，corn yield and economic benefit were thebest，reaching 14.32 t/hm² and 21 400 yuan/hm²，respectively，which was 48.60% and 33.75% higher than CK. All three organic fertilizers can improve soil fertilityin dryland，increase corn yield and increase economicbenefits，and the best effect when applied with chemical fertilizers at 3 t/hm².
