Effects of Minimum Tillage and No-tillage Systems on Crops Water Use Efficiency of Winter Wheat Relays Summer Maize Cultivation

摘要：

Investigation on the effects of minimum tillage and no-tillage on crops yield,crops water use efficiency (WUE) under the condition of winter wheat relayed with summer maize cultivation was carried out on irrigation field.Five tillage systems were considered at the experimental site in Longkou city,Shandong Province,China.The five tillage systems were as follows: conventional tillage with no straw turnover,conventional tillage with straw turnover,rotary tillage with straw turnover,serrated disk harrow tillage with straw turnover,no-tillage with straw cover.The soil moisture content was measured by oven drying method.Results showed that minimum tillage especially rotary tillage with straw returned could increase soil water content,crops WUE and crops yield of a whole year.Preliminary studies showed that rotary tillage with straw turnover could be adopted in this region,while no-tillage with straw cover returned was not suitable.
