摘　　要：通过研究施用两种缓效肥(IBDU和包膜缓效肥)对多年生黑麦草草坪草生长与质量的影响,证明我国北方地区春季施用缓效肥不但避免了草坪草旺长现象,还可获得较速效肥更持久和均一的草坪质量与生长量。但秋季施用缓效肥未表现出明显的优势,包膜缓效肥的效果甚至还低于施用尿素的效果。A field study on the effectiveness of two slow-release fertilizers （Isobutylidene diurea-IBDU and Polymer-coated fertilizer） on the quality and growth of perennial ryegrass was conducted in Northern China. The results indicated that the slow-release fertilizers applied in spring could sustain much longer acceptable and uniform turfgrass quality and biomass of growth compared with urea applied. However, applying slowrelease fertilizers to the perennial ryegrass turf in fall could not produce the improving effects on the turf quality. Polymer-coated fertilizer applied in fall showed somewhat lower applied. trufgrass quality than the ones with urea
