摘要 在桂林市农田灌溉试验中心站开展绿化草坪耗水试验,采用水量平衡法计算耗水量和耗水强度。结果发现:(1)冬季、春季绿化草坪的耗水量较低,夏、秋季节较高,年均耗水量835.8 mm;(2)绿化草坪日均耗水量呈“两头低、中间高”的变化趋势,平均耗水强度2.82 mm/d;(3)2019—2021年,绿化草坪耗水量与E601型蒸发量的相关系数R2分别达到0.658、0.7 546、0.734,表明二者具有显著的正相关性。 The water consumption test of green lawn was carried out at Guilin Farmland Irrigation Experimental Central Station. The water consumption and water consumption intensity were calculated by water balance method. The testing results showed that:(1) The water consumption of green lawn was lower in winter and spring, but higher in summer and autumn, with the annual average water consumption of 835.8 mm.(2)The average daily water consumption of green lawn had a change trend of low at both ends and high in the middle, with the average water consumption intensity of 2.82 mm/d.(3) From 2019 to 2021, the correlation coefficient(R2) between the water consumption of green lawn and the evaporation of E601 reached 0.658, 0.7546, 0.734, indicating that there was a significant positive correlation between them.
