| 摘 要： | 依据2004年试验资料,采用SAS统计分析软件,研究了在不同灌水量、灌水时间处理下,春小麦生长前期生长状况、干物质积累、最终产量及其组成、春小麦田的耗水量和水分利用率。结果显示:分蘖拔节期适当减少灌水量并推迟灌水时间,能抑制春小麦地上部分的生长,促进根系生长,减少总耗水量,提高水分利用率。 |
| 关 键 词： | 春小麦 调亏灌溉 灌水时间 灌水定额 SAS |

| Abstract: | Based on the data getting from field experiment in 2004,the SAS software is used to analyses the growth of plants and root,yield and its composition,water consumption and water use efficiency under different quantity of irrigation water and irrigation time in prophase.Results show that the growth of plants is limited,growth of root is enhanced,water consumption is reduced,water use efficiency increase apparently,yield has little reduce when reducing irrigation water and detaining irrigation time properly. |
| Keywords: | spring wheat regulated deficit irrigation water consumption water use efficiency |
