| 摘 要： | 在4种不同灌水梯度条件下,对高羊茅Festuca arundinacea和白三叶Tritolium repens两类不同草坪草的蒸散进行了研究,得出天津滨海地区草坪草的蒸散量变化规律.结果表明2种草坪草的蒸散量变化趋势基本一致.在4种不同灌水量条件下,白三叶的蒸散量远远大于高羊茅;每一种草不同灌水量梯度之间蒸散量的差异极其显著.

| Abstract: | The evapotranspiration of two different turfgrass species: Tall fescue(Festuca arundinacea) and Trifolium repens were studied under condition of 4 different watering gradients.The result showed that the tendency of the evapotranspiration change of the two turfgrasses was conformable.Under condition of 4 different watering gradients,ET of T.repens was much higher than Tall fescue;among different irrigation gradiengts,the discrepancy of the evapotranspiration of each turfgrass species was extermely notable.Accordingly the change law of turfgrass ET in Tianjin seashore region can be educed. |
