摘要： 采用蒸渗仪法,在田间实验充分供水条件下,研究修剪高度(4、6、8 cm和不修剪(对照))对高羊茅(Festuca arundinacea)和中华结缕草(Zoysia sinica)耗水量的影响及草种间的差异,根据水量平衡原理计算其耗水量。结果表明:供试草种的耗水量均随着修剪高度的增加而增加,草种间存在差异;其中修剪4 cm者较对照区耗水量减少23%;所得参数可为草坪节水和管理提供参考依据。

关键词: 修剪留茬高度, 蒸散量, 高羊茅, 中华结缕草

Abstract: To improve the water efficiency of turfgrasses,the effects of mowing height(4,6,8cm and without mowing) on evapotranspiration of Festuca arundinacea and Zoysia sinica were studied using water balance model under full water supply conditions.The results showed that the evapotranspiration amounts of both species increased along with the increasing of mowing height and there was significant difference between species.The average reducing percentage of water consumption under treatment with mowing height at 4cm reached to 22% in comparison with unmowed turfgrasses.The determined parameters could be expected to provide basic reference for water saving management in turfgrass.

Key words: Mowing height, Evapotranspiration, Festuca arundinacea Schreb.,Zoysia sinica Hance
