为研究园林草坪修剪物堆肥产品用作草花育苗基质的适宜配比和应用效果，探讨园林草坪修剪废弃物利用途径，本研究将福州市草坪修剪物用堆肥添加剂进行堆肥处理后，按25%(T1)、50%(T2)、75%(T3)、100%(T4)的体积比与园土混合作为育苗基质，以100%园土(CK)作为对照，检测其化学性质，并开展万寿菊(Tagetes erecta)、孔雀草(Tagetes patula)、三色堇(Viola tricolor)3种草花幼苗的生长栽培试验。结果表明，适当添加园林草坪修剪物堆肥能够改良土壤化学性质，提高土壤养分；T3(75%堆肥+25%园土)为万寿菊和孔雀草的最适育苗基质，T2(50%堆肥+50%园土)为三色堇的最适育苗基质。研究表明，适当添加园林草坪修剪物堆对草花生长有促进作用，但具体比例需要结合不同植物的特定属性和环境特点以确定。

The aim of this study was to study the suitable ratio and application effect of garden lawn trimming compost products as growth substrates for annual and biennial flowers and to explore the utilization approaches of garden lawn trimming waste. The lawn trimmings in Fuzhou were composted with additives. The compost was mixed at volume fractions of 25%(T1), 50%(T2), 75%(T3), and 100%(T4) with garden soil as the growth substrates, and 100% garden soil was used as the control(CK). The chemical properties of the substrates were determined and the cultivation experiments were carried out with Tagetes erecta, Tagetes patula, and Viola tricolor. The results showed that appropriate addition of garden lawn trimming compost improved the chemical properties and nutrients of soil. The optimal growth substrate for T. erecta and T. patula was T3(75% compost + 25% garden soil), while that for V. tricolor was T2(50% compost + 50% garden soil). Appropriate addition of garden lawn trimming compost can promote the growth of annual and biennial flowers, while the specific ratio needs to be determined considering the specific attributes and environmental characteristics of different plants.
