No tillage for winter wheat has been conducted in North China. A successive 2-years field experiment in winter wheat growing periods was carried out in Luancheng Experimental Station of CAS in 2003-2005. In the study, taking conventional tillage (CT)and rotary tillage(RT) as check, the dynamics of soil temperature and soil moisture under no-tillage (NT) was measured continuously. Soil physical properties were systemically studied in this paper, effects of No tillage on the growth of winter wheat, the yield ...
