Abstract: To select appropriate tillage method and improve soil fertility and grain yield and develop regional resource superiority in shajiang black soil, a field experiment was conducted to study the effects of 3 tillage methods [no tillage, rotary tillage (15 cm) and deep tillage (30 cm)] on soil bulk density, moisture, nitrate nitrogen and grain yield of winter wheat with‘Bainong207’as the material. The results showed that soil bulk density had no significant differences among the 3 tillage treatments in 0-10 cm soil layer (P ＞0.05), but deep tillage decreased soil bulk density in 10-40 cm soil layer significantly (P <0.05). The effect law of the 3 tillage treatments on 0-40 cm soil moisture was not obvious in wheat seedling period (P ＞0.05), but deep tillage significantly increased soil moisture of 0-40 cm soil layer in the wintering, jointing and maturity period (P ＜ 0.05). In 0-40 cm soil layer, the order of soil nitrate nitrogen content was no tillage＞ rotary tillage＞ deep tillage at maturity stage. Compared with no tillage, deep tillage increased grain yield by 9.79% by increasing grain number and 1000-grain weight. In view of soil properties, crop growth and natural environment, the deep tillage (30 cm) was a better management practice for shajiang black soil to decrease soil bulk density, improve soil moisture and increase grain yield of winter wheat.
