Abstract:The effects of integrated tillage pattern on maize yield, utilization efficiency and direction of nitrogen fertilizer in aeolian sandy soil of northeast China were studied, and the relationships between maize yield and nitrogen utilization efficiency under different tillage patterns were discussed, which would provide scientific basis for rational tillage pattern of maize production in this region. In the aeolian sandy soil region, 15N labelled micro-plots were set up in conventional tillage (CT), integrated tillage pattern 1 (ITP1) and 2 (ITP2) treatment, and CT was taken as contrast treatment. The effects of ITP1 and ITP2 on maize yield, utilization efficiency and direction of nitrogen fertilizer were studied. The results showed that the maize grain yield significantly increased by 30.10% and 15.53% in ITP1 and ITP2 compared with that of CT, respectively. The nitrogen utilization efficiency of three tillage patterns ranged from 27.10% to 35.46%. The nitrogen use efficiency was 35.46% and 31.40% in ITP1 and ITP2, respectively, which was 30.85% and 15.87% higher than that of CT. Compared with CT, the residual nitrogen of ITP1 increased by 18.67%, and the loss rate decreased by 45.65%. The residual nitrogen of ITP2 was lower than that of ITP1, but higher than that of CT, but the difference was not significant. However, the nitrogen loss rate of ITP2 was 24.36% lower than that of CT and 39.17% higher than ITP1. Both of integrated tillage patterns increased maize yield and nitrogen use efficiency, and decreased nitrogen fertilizer pollution. Thus, IPT1 and IPT2 were potential strategies for increasing maize yield in aeolian sandy soil of northeast China.
