| 摘 要： | 在滨海盐碱地区，水分，盐分的胁迫，使草坪草体内矿质营养失衡，生长势减弱，在秋季即使轻微水分胁迫，都会使草坪草休眠提前，绿色期缩短，试验发现，秋冬季给高羊茅施用尿素或EDTA－Fe都可以改善其绿色度，增加叶片内叶绿素的含量，延迟草体进入休眠，并能加快春季返青的速度，但尿素和EDTA－Fe的交互效应在本试验中不显著。

| Abstract: | Extreme saline, interacting with drought, usually results in a fall in growth potential and inbalance in mineral nutrient absorption of turfgrasses in coastal areas. Water stress, even slightly, can cause a loss of chlorophyll and dormancy of turfgrasses in autumn. Experimental results indicated that autumn plus winter (September to December) applications of urea could successfully postpone dormancy and enhance post-dormancy growth, similarly, accelerate turfgrass rapidly green-up. The contents of chlorophyll in leaves were significantly higher with urea than without. In addition, EDTA-Fe, When applied alone, positively influenced the color ratings of tall fescue; however, the interaction of urea treatment and EDTA-Fe treatment was not significant. |
