Abstract：In order to screen out the field management measures to improve the soil water holding capacity,the effects of deep tillage,straw mulching,increasing application of organic fertilizer,water retention agent and zeolite on bulk density,water storage capacity,nitrogen content and other physical or chemical properties of brown soil and the crop yield were studied under the wheat-maize rotation condition in field.The resuits showed that compared with the recommended fertilization treatment,the treatments of increasing application of organic fertilizer,deep tillage,straw mulching,zeolite and water retention agent all could decrease the soil bulk density,increase the soil porosity,and improve the soil available water storage capacity and crop yield in different extent.The soil bulk density declined by 0.72％ ～9.21％,the soil porosity increased by 0.30％ ～ 14.25％,the soil available water storage capacity increased by 0.05％ ～ 10.91％,and the crop yield increased by 0.07％ ～10.68％.Comprehensively considering all the indexes,the field management measures,which could increase the soil water holding capacity and ensure the crop yield at the same time,were the treatments of increasing application of organic fertilizer and zeolite.The zeolite treatment had the largest increase of soil available water storage capacity.The increasing application of organic fertilizer treatment had the best effect on the crop yield improving.
