Abstract:According to the national environment,social and economical situation in loess hilly areas,the suitable tillagetechniques with soil and water conservation have been taken. The objectives of storing water,conservating soil,in-creasing fertility and yield,decreasing field in order to plant trees and grasses on slope land,and making the a-griecosystem into favourable circle cap be achieved through applving these techniques. Therefore,on the basis ofplanting. in level furrow in a large range,the experiments have been made to study tillage techniques with soil andwater conservation,which includes covering soil with film;reserving stubble for inversing ridge; putting soil blockin furrow; intercropping and rotation of grass and grain in belt shape and intercropping of grain and grass as well asbush in wider belt on slope land,etc. The benefits of storing water,retainning soil,increasing fertility and yield andincreasing return for every technical measures have been evaluated.
