| 摘 要： | 通过温室试验,研究了不同灌溉处理对玉米的生长状况,生理特性及产量和水分利用率的影响。结果表明,充分灌溉处理(FI)的植株株高、茎粗与叶面积长势优于其它处理,而地上部分及根系的干物质累积量低于其它处理。相同的灌溉量条件下,分根交替灌溉处理(PRD)的植株产生的脯氨酸含量高于调亏灌溉处理(DI),说明PRD处理能够使植株提高渗透调节能力。在产量构成中,FI处理的植株产量最高,PRD 75%(灌水量为充分灌溉的75%)处理的植株产量略低于FI处理,二者差异不显著,其次为D I75%处理(灌水量为充分灌溉的75%)。尽管FI处理的植株绝对产量最高,但是以牺牲水分利用率为代价的,而其它处理尽管绝对产量较FI处理略低,但由于其耗水量也低,水分利用率反而高于FI处理。特别是PRD 75%处理的植株绝对产量和水分利用率都有较好的表现。

| Abstract: | The growth,physiological characteristics,yield and water use efficiency of corn were studied under different irrigation treatments in greenhouse.The results show that the growth of plant height,stem diameter and leaf area under full irrigation treatment(FI)increased more than the other treatments.However,the accumulation of root and above-ground dry matter were decreased.Compared with the same apply of water,plants under partial root dry treatment(PRD)had more effective osmotic regulation capacity than that... |
