摘    要:研究了深圳地区不同灌水处理对马尼拉草坪草蒸散量和生长特性的影响。结果表明,不同的灌水处理显著影响马尼拉草坪草的蒸散量(P〈0.05),供水多,蒸散量大,供水少,蒸散量小。在80%~100%田间持水量(FC)和50%~80%FC灌水处理下,草坪草质量都可以达到理想的水平,不影响草坪的景观效果,50%~80%FC的灌水量适宜马尼拉草坪的灌溉,可以节约灌溉用水,而30%~50%FC灌水处理下,草坪草质量较差。草坪草的生长速率随着水分梯度的增加生长加快。3种处理叶片的叶绿素含量差异不显著。平均月蒸散量与气象因子之间有显著的相关关系,3种水分梯度下的蒸散量同时受气温、日照时数、湿度、风速4种气象因子的影响。’

关 键 词:灌水处理  马尼拉草  蒸散量  草坪质量  生长速率

Abstract:Effect of different irrigation treatments on the evapotranspiration and growth characteristics of Zoysia matrella was studied in Shenzhen.The results showed that different irrigation treatments could significantly influence the evapotranspiration of Zoysia matrella(P<0.05).The evapotranspiration increased along with the irrigation amount.Turfgrass quality could reach the satisfactory level under the irrigation level of 50% to 80% of field capacity(FC).And this was the proper irrigation level for Zoysia matr...
Keywords:irrigation treatment  Zoysia matrella  evapotranspiration  turfgrass quality  growth speed
