施肥对草坪土壤养分及旅游景观草坪质量的影响

Effect of Fertilization to Turf Soil Nutrients and Tourism Landscape Turf Quality

旅游景观草坪是城市园林景观的重要组成部分,实际养护中注重科学施肥技术的应用对提高草坪质量具有重要意义。以草坪施肥的特点为基础,分析了施肥对土壤养分的影响以及草坪施肥后土壤养分的动态变化规律,对指导草坪合理施肥具有重要意义;以早熟禾、结缕草、黑麦草、沟叶结缕草为例,指出了施肥后其生长状况、叶绿素含量的变化,明确了草坪施肥的主要方向,以期为旅游景观草坪科学养护提供理论依据。

Tourism landscape turf is an important part of the urban landscape, attention to scientific fertilization technology to improve the turf quality is of importance to effective conservation. In this paper as the basis of the characteristics of turf fertilizer, we analyzed the effects of fertilization on soil nutrients and law of dynamic changes of soil nutrients after turf fertilization to give guidance to turf rational fertilization. In this paper we used Poa pratensis L., Zoysia japonica, Loliumperenne L., Zoysia matrella as the example, pointed out changes of that the growth condition after fertilization and chlorophyll content and defined the main direction of turf fertilization to provide a theoretical basis for the tourism landscape lawn maintenance science.
