Abstract
In order to study the effects of different tillage management on soil rapidly available nutrient content and the yield of winter wheat, four treatments of once deep plowing tillage (DT), no tillage (NT), subsoiling tillage (ST) and conventional tillage (CT) were conducted in field. The results showed that conservation tillage can improve soil nutrient content. Soil alkali-hydrolysis nitrogen, available phosphorus and potassium content were outstandingly advanced under ST and NT compared with CT, and the effect of ST was better than that of NT. In contrast to CT, available potassium content was evidently increased under DT treatment. Compared with CT, the grain yield of NT and ST was increased by 10.22% and 9.26% respectively.
