| 摘 要： | 对不同供水条件下,草地早熟禾、高羊茅、多年生黑麦草、野牛草、结缕草和狗牙根整个生长季的蒸散量差异进行研究.结果表明,草坪蒸散主要与草坪本身的生物学特性有关,同时与水分条件也密切相关.另外,根据测定结果估测了理论补水量,并通过计算坪草系数Kc,与北方常用作物的耗水量进行了比较.

| Abstract: | Under different water supply conditions in the field, the evapotranspiration (ET) of Kentucky bluegrass, tall fescue, perennial ryegrass, buffalograss, Japanese lawngrass, and Bermudagrass was investigated by the microlysimeter method. The results indicated that the ET of the six turfgrasses was mainly influenced by the turfgrass species, and also closely related to the water condition. The needed water supplement levels were estimated based on the ET. Through calculation of the turf Kc coefficient, a comparison was made with water consumption of common crops in northern China. |
