【摘要】：草坪是城市绿化不可缺少的组成部分,草坪的生长发育受到土壤养分的影响,通过测量江西省宜春市40个样地的不同游憩型草坪和观赏型草坪的质量指标及土壤养分,采用SPSS软件分析,探讨二者的相关性,结果表明:氮元素与游憩型、观赏型草坪的整体质量评分结果存在显著的正相关(P≤0.01),钾元素与游憩型草坪的整体质量评分结果存在中度的正相关(P≤0.05)。从草坪各质量指标来看,氮元素与游憩型、观赏型草坪的多项质量指标具有相关性(P≤0.05),在观赏型草坪中,磷元素与多项质量指标具有相关性(P≤0.05),钾元素在游憩型草坪中还与草坪高度相关(P≤0.01)。
[Abstract]:Lawn is an indispensable part of urban greening. The growth and development of lawn are affected by soil nutrients. The quality indexes and soil nutrients of different recreational and ornamental turfgrass in 40 plots of Yichun City, Jiangxi Province were measured. The correlation between nitrogen and recreational type was analyzed by SPSS software. There was a significant positive correlation between the total quality score of ornamental lawn and the total quality of recreational turfgrass (P 鈮，
