摘　　要：通过比较速效肥与缓效肥对多年生黑麦草草坪质量与坪草生长的影响,证明施用缓效肥不但可以使坪草生长更趋均匀,而且还可长久地维持草坪质量。尤以日本包膜缓效肥与德国产的IBDU效果突出。试验结果表明,在华北地区冷季型草坪上,春季以缓效肥为主,配合一定比例的速效肥,而秋季以速效肥为主,配合施用缓效肥,即可满足春季坪草快速生长和草坪越夏对养分的需求,又可使草坪保持较高的质量,并为草坪越冬打下良好的营养基础。A field study on the effectiveness of several types of fertilizers on the quality and growth of perennial ryegrass was conducted in northern China. The results indicated that the slow-release fertilizers not only made more uniform growth, but also sustained much longer acceptable turf quality, especially for applied isobutylidene diurea-IBDU and polymer-coated fertilizer treatments. The results revealed that applying slow-release fertilizer as main source and combining appropriate proportion of readily available fertilisers in spring could meet the nutrient requirements of turfgrass for rapid growth in spring, and applying readily vailable fertilizers as main source and combining with slow-release fertilizer could assure the high turfgrass quality and build a strong basis for the turfgrass survival in winter.
