| 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。

| Abstract: | 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 slow-release 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 trufgrass quality than the ones with urea applied. |
