Moreover, it puts forward some suggestions on how to develop conservation tillage in china. The research on conservation tillage of china should play more emphasis on the application of enginery, adjusting suitable measures of local conditions and the weeding of the weeds. At the same time the research on conservation tillage ought to study well the variety of soil characteristics and the effects of crop yield after adopting the measures of conservation tillage then establish the specifications of conservation tillage which according to local productivity conditions. |
