| الوصف: | Diversified cropping systems can enhance soil condition and increase system productivity worldwide. To reduce the negative effects that accompany the continuous winter wheat&ndash summer maize (WM) double-cropping in the North China Plain (NCP), diversified crop rotation (DCR) needs to be considered. The objective of this study is to evaluate the effect of DCR on soil health and wheat productivity as compared to a continuous WM double-cropping. A field experiment (37° 41&prime N, 116° 37&prime E) was established in the NCP including a traditional WM double-cropping as a baseline. During 2016/2017&ndash 2017/2018, the control is winter wheat&ndash summer maize&rarr winter wheat&ndash summer maize (WM&rarr WM) and seven DCRs as follow: fallow&rarr summer maize (F&rarr WM) spring maize&rarr summer maize (Ms&rarr winter wheat&rarr summer maize (W&rarr sweet potato&rarr summer maize (Psw&rarr spring peanut&rarr summer maize (Pns&rarr summer peanut&rarr summer maize (WPn&rarr WM) and potato&ndash silage maize&rarr summer maize (PMl&rarr WM). Our results indicated that DCRs significantly changed certain soil health indicators in 2016/2017 compared with the control, where F&rarr WM rotation significantly decreased soil pH by 2.7%. The DCRs, especial Psw&rarr WM and Pns&rarr WM rotations showed a potential positive effect on soil health indicators at the end of the second year (2017/2018) compared with the control, where sweet potato increased soil organic carbon (SOC), total nitrogen (TN), available phosphorus (AP), urease activity (UA) and alkaline phosphatase activity (APA) in 2017/2018 by 5.1%, 5.3%, 13.8%, 9.4%, and 13.5%, respectively. With the spring peanut, TN, AP, and soil APA were increased by 2.1%, 13.2%, and 7.7%, respectively. Although fertilizer and irrigation input of DCRs were lower than the control, no significant decrease was observed on actual wheat yield as compared to the control (7.79 Mg/ha). The finding of this study highlights the value of DCRs, especially, Psw&rarr WM rotations over WM double-cropping in the NCP. |
