摘　　要：控释肥对草坪生长和土壤环境有不少益处,但控释肥在亚热带暖季型草坪上的施用在国内还缺乏研究。试验在东莞长安高尔夫球场“Tifway”杂交狗牙根、从化从都高尔夫球场“Supereme”海滨雀稗和佛山高尔夫球场“Tifsport”杂交狗牙根草坪上开展,对普乐夫控释肥和普通球道肥对草坪坪用性状以及土壤性质进行比较评价。结果表明,施用普乐夫肥料的草坪坪用质量均显著高于普通球道肥,在东莞试验地和从化试验地,普乐夫肥料施量30g/m^(2)坪用性状最佳;除了东莞试验地根系长度,普乐夫肥料施量25g/m^(2)处理的其他坪用性状与施量30g/m^(2)处理的均无显著差异。施用普乐夫肥料的草坪土壤有效氮磷钾含量和土壤电导率均显著高于普通球道肥,说明普乐夫肥料在土壤中的养分流失较少。综合评价后认为,在亚热带暖季型草坪上,普乐夫肥在生长季节每两个半月施用一次,施肥量以25g/m^(2)为宜。Controlled-release fertilizer has a lot of benefits on lawn growth and soil environment,but there is still a lack of research on the application of controlled-release fertilizer on subtropical warm season lawn in China.The experiment was carried out on Tifway hybrid bermudagrass in Dongguan Chang’an Golf Course,Supereme hybrid Paspalum vaginatum in Conghua Congdu golf Course and Tifsport hybrid bermudagrass in Foshan Golf Course to compare and evaluate the turf characters and soil properties of Proturf controlled release fertilizer and common fairway fertilizer on the lawn.The results showed that the quality of the lawn applied with Proturf fertilizer was significantly higher than that of the common fairway fertilizer,and the application amount of 30 g/mof Proturf fertilizer was the best in the dongguan and conghua experimental plots.Except for the root length of the dongguan test ground,there was no significant difference between the othe rturf characters treated with 25 g/m^(2) Proturf fertilizer and 30 g/m^(2) fertilizer.The available N,P,K content and soil electrical conductivity of lawn fertilized with Proturf fertilizer were significantly higher than that of common fairway fertilizer,indicating that the nutrient loss of Proturf fertilizer in soil was less.After comprehensive evaluation,it was concluded that in the subtropical warm season lawn,Proturf fertilizer was applied every two and a half months in the growing season,and 25 g/m^(2) fertilizer was Optimum fertilization.
