| Abstract: |
| To supply scientific evidences of saving water, a study was made on effects of different irrigation quota on the growth and yield of spring wheat in field conditions in arid and semiarid regions. The results showed that the growth and yield of spring wheat was unchanged under irrigation quota of 4 286 m3/hm2 (209 m3/hm2 less than comparison treatment). Though irrigation quota of 3 670 m3/hm2 (825 m3/hm2 less than comparison treatm
ent) influenced the growth of spring wheat, but the yield did not reduce obviously. Irrigation quota of 3 060 m3/hm2 (1 435 m3/hm2 less than comparison treatment) affected the growth of spring wheat badly: plant height reduced, dry weight and fresh weight decreased, yield reduced obviously. In common years, fitting irrigation quota was 3 900～4 200 m3/hm2 and water-saving potential was 200～500 m3/hm2 in irrigation region in Ningxia. |
