Abstract:To investigate the effects of different tillage measures on maize yield and nitrogen(N) and phosphorus(P)leaching, the field experiment was conducted in the burozem cropland for single maize of Northeast China. Four treatments were designed, including rotary-tillage(RT), no-tillage(NT), deep ploughing-tillage(DT), and deep ploughing with straw incorporation(DTS). We determined the effects of different treatments on N and P leaching, nutrient pools in arable layer, and maize yield. The results showed that compared to RT, NT treatment decreased the flow amount of leaching and N/P leaching, while maize yield was reduced. DT treatment increased the flow amount of leaching, whereas nutrient pools in arable layer and maize yield were enhanced, indicating the regulating effect on N/P leaching. DTS treatment decreased the flow amount of leaching and N/P leaching, and additionally improved nutrient pools in arable layer and maize yield. In conclusion, the no-tillage measure was more effective for N/P leaching control than deep ploughing-tillage. Furthermore, the deep ploughing with straw incorporation was more beneficial for reducing the loss risk of N/P leaching.
