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。
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 STOCKSOR B 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/m^2, or ‘ Nuglude＇ Kentucky bluegrass is 75g/m^2, for ‘ Pickwick＇ perennial ryegrass is 25-75 g/m^2, for Japanese lawngrass is 75g/m^2.
