| Abstract: |
| The working performances of four kinds of
typical tine furrow openers were measured on no-tillage soil mulched with wheat stubble.
The working force of furrow openers and its effects on the physical properties of soil
were analyzed. The experiment results showed that the four types can all work properly on
no-tillage soil except the wide-winged one. |
