| Abstract: |
| Field experiments
on the coupling effect of water and fertilizer on the intercrop of summer corn with drip
irrigation have been conducted. The results showed that there are 4800m3 water
per hectare of summer corn can be consumed, and applying N and P2O5
at rates of 175k.hm-2 and 145k.hm-2
respectively in entire corn season, yield of summer corn has reached more than 9450k.hm-2,
and WUE(water use efficiency) over 1.9kg.m-3. The
effective measures can results in obvious effects of water-saving and yield-raising. |
