摘　　要：对匍匐翦股颖品种Penneross、粤选1号和新品系粤选2号、粤选3号的果岭及绿地草坪蒸散量的研究表明，广州地区5月中旬匍匐翦股颖果岭草坪蒸散量低于绿地草坪，且粤选1号〈Penneross〈粤选3号〈粤选2号，其果岭草坪蒸散率分别为3．10～3．39、3．62～3．86、4．02～4．46、4．18～4．66mm／d，绿地草坪蒸散率分别为4．04～4．23、4．26～4．52、4．50～4．92、5．08～5．58mm／d．按Beard草坪蒸腾量划分，4种品种的草坪日蒸散量均属中偏低以下水平．The evapotranspiration rates of Agrostis stolonifera among cultivars Penncross , Yuexuan No. 1 as well as new strains Yuexuan No. 2 and Yuexuan No. 3 for golf green and amenity were studied. The results showed that evapotranspiration rates for golf green were lower than those of amenity in May in Guangzhou area, and the rank evapotranspiration rates of Agrostis stolonifera cultivars were Yuexuan No. 1 〈 Penncross 〈 Yuexuan No. 3 〈 Yuexuan No. 2, the evapotranspiration rates for golf green were 3. 10 - 3.39,3.62 - 3.86,4. 02 - 4. 46,4. 18 - 4. 66 mm/d, respectively; and those for amenity 4. 04 - 4.23, 4.26 -4. 52,4. 50 -4.92,5.08 - 5.58 mm/d. According to Beard＇ s evapotranspiration classification, the evapotranspiration rates for golf green of Penncross and Yuexuan No. 1 were very low, and those for amenity, low. The evapotranspiration rates of Yuexuan No. 2 for golf green were low, and those for amenity, medium-low. The evapotranspiration rates of Yuexuan No. 3 for golf green and amenity were low.
