The systematic experiment of conservation tillage in two crops a year region has been designed and performed according to the maximum benefit of resources, environment and production, based on the research achievements of conservation tillage technology in one crop a year regions. Series experiments and embedded theory study have been conducted for estimating the feasibility of water saving in conservation tillage and guiding irrigation. At the same time, the evaporations of soil water under the condition of conservation tillages are measured and its mathematic model is studied and significant research achievements have been obtained.
