| 摘 要： | 采用盆栽模拟大田试验方法，对北京地区3种暖季型单播草坪进行蒸散量研究，结果表明：3种草坪充分灌水条件下蒸散量高于限制灌水条件，其蒸散量顺序为狗牙根〉结缕草〉野牛草；3种暖季型草坪蒸散量随土壤含水量的增加而增加，呈正相关关系，其关系式为：狗牙根为y=1．051z＋2．523（R^2=0．914）；结缕草为：y=1.135z＋3．105（R^2=0．984）；野牛草为：y=0．801x＋2．948（R^2=0．865）。一天内蒸散量呈现单峰变化趋势，并且709，5～809／6的蒸散量时间集中在10：00-16：00。 |

| Abstract: | The evapotranspiration(ET) of 3 warm season turfgrasses was studied with pot experiment in Beijing.The result showed that the ET of 3 warm-season turfgrasses was higher under sufficient irrigation than that under limited irrigation,and the order of ET was Cynodon dactylon>Zoysica sinica>Buchloe dactyloides.Under the different soil water contents,the ET decreased with the decrease of soil moisture.The daily variation of ET showed a single peak curve,and the transpiretion mainly occurred from 10: 00 to 16: 00... |
