| Abstract: |
| On the basis of tests and researches in room,and by three years of field test for the amount of water which affects the performance of no-tilt watering and planting for corn,it is proved that no-tilt watering and planting for corn has such merits as increasing products by 17.3%,saving irrigation water by 20.97%,improving the organic matter content by 6.09% after three years of stock returning and decreasing the hardness of tilt layer soil by 7.2%.It is concluded that no-tilt watering and planting machine for corn is the first planting equipment to be selected and used in grain crop fields of wheat and corn. |
