　　 In the North China Plain（NCP）, soil deterioration threatens winter wheat（Triticum aestivum L.） production. Although rotary tillage or plowing tillage are two methods commonly used in this region, research characterizing the effects of mixed tillage on soil characteristics and wheat yield has been limited. A fixed-site field trial was carried out during 2011–2016 to examine the impacts of three tillage practices(5-year rotary tillage with maize straw removal（RT）; 5-year rotary tillage with maize ...
