高尔夫球场草屑循环再利用研究

         

摘要

本研究旨在探讨高尔夫球场草屑的循环再利用问题.试验以高尔夫球场修剪下的草屑为主要原料,将草屑与鸡粪有机肥分别按100%∶0%、90%∶10%、80%∶20%、70%∶30%的不同比例混合后加入菌剂进行发酵,发酵过程中测定温度、pH值、植物毒性等腐熟度指标,以判断草屑发酵的腐熟程度,最后对发酵产物进行养分分析;将4种发酵产物分别与细沙按照1∶1比例混合后作为基质,用兰引Ⅲ号结缕草进行栽培试验,通过测定草坪草密度、盖度、叶绿素含量、地上部分生物量、地下部分生物量等指标,对混合基质进行评价.研究结果表明,草屑与有机肥混合发酵,加入有机肥的量以20%为宜,21d后发酵成熟,发酵产物pH适中,养分含量丰富,使用安全,与沙构成的混合基质可显著提高草坪质量,可作为草坪栽培基质进行资源化有效利用.%Utilization of clippings as a recycling resource on a golf course were studied using a composting exper-iment with turf-grass clippings mixed with chicken dung organic fertilizers at ratios of 100% : 0%, 90% : 10%, 80% : 20% , and 70% : 30%. Microbial inocula were added to improve clippings for reuse on golf courses. The composting maturity was determined by testing temperature, pH, and germination index during composting and matured composts were analyzed for nutrient content. The four matured composts mixed with fine sand at a ratio of 1 : 1 were evaluated as turf growing media using Zoysia japonica cv. Lanyin No. III and measuring turf-grass density, coverage, chlorophyll content, aboveground biomass, and underground biomass. Clippings mixed with 20% organic fertilizer were suitable for composting, but needed 21 days to be well matured with an appropriate pH, good fertility, and safety. The compost mixed with sand significantly increased the turf quality, so that the golf course clippings could be reused as a resource for turf growing media.
