| Notes | LI Chao-su, TANG Yong-lu , HUANG Gang, WU Chun, MA Xiao-ling （Crop Research Institute, Sichuan Academy of Agricultural Science, Sichuan Chengdu 610066, China） 51-1213/S The wheat-rice rotation system was the major cropping system in south Asia and the Yangtze River Basin of China. From 2004 to 2009, the effect of different annual tillage patterns on crop yields and soil properties in a wheat-rice rotation system was studied in the Cheng- du Plain. The effects of four tillage patterns （annual plowing, no-tillage in wheat season with rice straw returning and rotary tillage in rice season, annual no-tillage with rice and wheat straw returning, annual ridge-no-tillage with rice and wheat straw returning）were tested in the experiment. The results showed that the difference in wheat yield among different treatments in the same year was not significant, but the difference in rice yield was obvious. The rice yield of the treatments with annual no-tillage and total straw mulching was lower than that of the control treat |
