Double‐Delay cropping patterns can significantly reduce agricultural water consumption without yield reduction. Annual decreased content is attributed to the in winter wheat season. Late sown consumes less before pre‐winter. Increased maize offset reduced appropriate systems. Appropriate increase annual profit. This study examined impact of delaying sowing time ( Triticum aestivum L.) and harvesting Zea mays on crop yields a region with warm temperature continental monsoon climate. According farmers’ practice (FP), we employed three treatments that each delayed both for 10 d, 20 30 d. No significant differences were observed grain among FP, d (DHS‐10), (DHS‐20), while results these higher than those treatment (DHS‐30). For all treatments, delay summer increased harvesting. rotation, improved season compensated season, DHS‐10 DHS‐20 compared FP. Total followed as DHS‐10, DHS‐20, DHS‐30 order. by 5.6 10.7%, respectively, Higher net economic benefits FP was also obtained (+ 495.4 ¥ ha −1 ) 877.0 treatments. In conclusion, not only substantially total consumption, but maintained stable profits.
