| 摘 要： | 采用单因素随机区组设计，以灌水为试验处理，研究高羊茅（Festuca arundinacea）生育期内不同月份的蒸散量与其草坪质量之间的关系。结果表明，处理Ⅰ（田间持水量100%～80%）、Ⅱ（田间持水量80%～60%）、Ⅲ（田间持水量60%～40%）下，草坪质量与蒸散量有一个界限值，当蒸散量小于此界限值时，草坪质量随草坪蒸散量的增加而增加，且增加的幅度较大；当大于该界限值时，草坪质量不再增加，草坪质量随草坪蒸散量的增大而减小，呈现出抛物线关系。处理Ⅳ（田间持水量40%~萎蔫含水量）条件下，草坪质量与蒸散量在试验期内呈线性关系。不同水分条件下，草坪草蒸散量对草坪质量的影响显著。

| Abstract: | The trial was conducted to determine the relationship between evapo-transpiration and turf quality of Festuca arundinacea in the growth moment by single random grouping design in Beijing.This study indicated that the turf quality was significantly influenced by the turfgrass ET under the different moisture conditions.The turfgrass ET changing the turf quality had a limit threshold value,indicating that the turf quality was increased with the increase of ET when the ET was less than the threshold value and t... |
