采用盆栽的方法,通过控制浇水量设置了3个水分梯度,研究水分胁迫对结缕草叶片生长的影响。结果表明:水分胁迫明显降低了结缕草叶片长、宽,严重干旱减少了分蘖叶片数量,使光合面积减少。重度干旱下,叶片寿命缩短。因此,结缕草在轻度、中度干旱下能维持较正常的生长,证实了结缕草的耐旱性。但结缕草不能长期适应重度干旱环境。对结缕草的应用和草坪管理提出了建议。 Pot experiments were conducted to study the effects of water stress on the growth of zoysiagrass by setting three water gradients by controlling watering. The results showed that water stress significantly reduced the length, width and serious drought of Zoysia japonica reduced the number of tillering leaves and decreased photosynthetic area. Severe drought, blade life shortened. Therefore, Zoysia japonica could maintain a more normal growth under mild and moderate drought, confirming the drought tolerance of Zoysia japonica. However, Zoysia can not adapt to severe drought conditions for a long time. Proposals are made for the application of zoysiagrass and turf management.
