摘要
依据在田间小区的试验,对不同水分条件下冬小麦的生长特性进行了研究,结果表明:水分胁迫使小麦生长速度、叶片伸展速度降低,植株叶面积减小。氮和磷素营养对小麦生长生理特性具有明显的调控作用,但两者调控机理明显不同。
According to the field plot experiment, this paper studied growth characters of winter wheat under different water conditions. The results indicated that relative growth rate (RGR), relative leaf extension rate (RLER) and leaf area ratio (LAR) were reduced by water stress. The adjustment effects of nitrogen and phosphorus on growth characters of winter wheat were found, while adjustment mechanism were not the same between nitrogen and phosphorus.
