| 摘 要： | 高羊茅(贝克)、草地早熟禾(新哥来德)、多年生黑麦草(匹克威)、中华结缕草、狗牙根(萨旺那)5种常用草坪草在播种建植草坪时土壤混合STOCKSORB保水剂,研究保水剂的节水效果。结果表明:足量供水,保水剂用量不超过75g/m2可节约用水28.9～67.2mm;限量供水,使用保水剂可节约用水12.6～52.7mm。根据综合表现看,在草坪草上使用STOCKSORB适宜用量分别为:高羊茅25g/m2、草地早熟禾75g/m2、多年生黑麦草25～75g/m2、中华结缕草75g/m2。

| Abstract: | We mixed STOCKSORB,a superabsorbent polymers,with soil to study its effects on water-saving of five kinds of turfgass: 'Pixie' tall fescue,'Nuglude'Kentucky bluegrass,'Pickwick' perennial ryegrass,Japanese lawngrass and 'Savannah' bermudagrass.The results indicate:in condition of sufficient irrigation,using STOCKSORB can save water 28.9～67.2mm and in deficit irrigation,it can save water 12.6～52.7mm.The suitable amount of STOCKSORB used in 'Pixie' tall fescue is 25g/m2,or'Nuglude'Kentucky bluegrass is 75g/m2,for 'Pickwick'perennial ryegrass is 25~75 g/m2,for Japanese lawngrass is 75g/m2. |
