| 摘 要： | 在沈阳地区潮棕壤土上,采用蒸渗仪对不同控制性交替灌溉处理下玉米生长发育、产量和水分生产效率进行分析。结果表明,控制性交替灌溉抑制了玉米地上部分生长,处理2(控制隔沟交替灌水,灌水定额为2/3M)的产量最高,比处理1(均匀灌水,灌水定额为M)增产4.8%,节水13.3%,处理3(控制隔沟交替灌水,灌水定额为1/2M)最节水但产量最低,确定处理2(2/3M)为最优灌溉制度。 |
| 关 键 词： | 控制性交替灌溉 玉米 生长发育 水分生产效率 灌溉制度 |

| Abstract: | The lysimeter was adopted to investigate growth, yield and water use efficiency of corn on aquic brown soil in Shenyang under different treatments of controlled alternate irrigation.The results indicated that controlled irrigation restrained the growth of overground part of corn effectively.Compared with treatment 1(irrigation quota: M),treatment 2(irrigation quota: 2/3M) increased yield by 4.8%,and decreased water consumption by 13.3%;treatment 3(irrigation quota: 1/2M) consumed the least water and its yield was also the lowest.Therefore,treatment 2 was determined as the optimal irrigation system. |
| Keywords: | controlled alternate irrigation corn growth water use efficiency irrigation system |
