【摘要】：草坪是城市綠化不可缺少的組成部分,草坪的生長發(fā)育受到土壤養(yǎng)分的影響,通過測量江西省宜春市40個(gè)樣地的不同游憩型草坪和觀賞型草坪的質(zhì)量指標(biāo)及土壤養(yǎng)分,采用SPSS軟件分析,探討二者的相關(guān)性,結(jié)果表明:氮元素與游憩型、觀賞型草坪的整體質(zhì)量評分結(jié)果存在顯著的正相關(guān)(P≤0.01),鉀元素與游憩型草坪的整體質(zhì)量評分結(jié)果存在中度的正相關(guān)(P≤0.05)。從草坪各質(zhì)量指標(biāo)來看,氮元素與游憩型、觀賞型草坪的多項(xiàng)質(zhì)量指標(biāo)具有相關(guān)性(P≤0.05),在觀賞型草坪中,磷元素與多項(xiàng)質(zhì)量指標(biāo)具有相關(guān)性(P≤0.05),鉀元素在游憩型草坪中還與草坪高度相關(guān)(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，
