Abstract: In order to make clear the possibility to extend conservation tillage in the middle and south area of Hebei Province, a field experiment including three tillage treatments, namely, no-tillage, deep loosing and rotary tillage, were conducted in Lian Zhou, Gao Cheng in 2003—2004.This article analyzed relationship between wheat yield, yield components and water content of soil under different Tillage Techniques. The results showed that no tillage and deep loosing could improve soil structure and water holding capacity, and then increase water use efficiency and yield. So it is necessary and prospective to extend the conservation tillage techniques-no tillage and deep loosing.
