[Objective] The aims of this study are to reveal the annual adaptive change pattern of soil moisture in dryland wheat fields in response to maize manure returning in summer fallow period, to elucidate water-driven mechanisms for wheat yield improvement and optimization by maize manure returning patterns, and to provide the theoretical references for dry farming water storage technology. [Methods] Trials of maize manure returning in summer fallow period were carried out in southern Shanxi dryland wheat fields, which adopted a regional comparison method. The no-tillage treatment during the summer fallow period was used as a control. The annual wheat field's soil water storage and consumption variation rules under summer fallow period maize manure returning were studied. Its effects on yield of succeeding wheat and efficiency of water use were also analyzed in this experiment. [Results] Compared to the no-tillage treatment, the treatment of maize manure returning in summer fallow period could significantly increase 0—200 cm soil annual water storage amounts, which also had a better soil water storage capacity in deeper layer. The amounts of 0—200 cm soil moisture consumption and water consumption percentage of maize manure returning treatment were significantly lower than those of no-tillage treatment. The manure returning treatment could improve 0—200 cm soil surplus water amounts during summer fallow period, and reduced 0—100 cm shallow soil layer's water dissipation amounts compared with no-tillage pattern. The wheat spike number and kernels per spike of manure returning treatment were significantly higher than those of no-tillage pattern, but the difference of thousand-grain weight between two treatments was not significant. The efficiency of 0—200 cm soil layer water storage for rainfall under manure returning treatment was significantly higher than that of no-tillage pattern in summer fallow period. The returning field biomass in maize manure returning treatment was significantly greater than that of no-tillage pattern in summer fallow period. The biological yield's precipitation and water use efficiency of maize manure returning treatment were significantly higher than those of no-tillage pattern in wheat season and anniversary stage. The same variation trend was observed in grain yield's precipitation and water use efficiency. [Conclusion] In dryland wheat field humid years, the summer fallow period maize manure returning treatment could significantly improve soil water storage amounts of dryland wheat field, which also reduced crops annual water consumption and optimized the three elements of wheat yield. Finally, the maize green manure returning pattern will increase wheat yield by more soil impoundage.
