脲醛泡沫栽培基质草坪质量综合评价

Quality Synthetic Evaluation of Urea Formaldehyde Foam Substrate in Turf Establishment

[目的]探讨3种脲醛泡沫栽培基质建植高羊茅草坪的可行性,并对草坪质量进行评定。[方法]将草坪外观质量、生态质量和实用指标作为综合质量评定的一级指标,对应的草坪密度、色泽、质地、均一性,绿期、盖度、生物量,出苗势、生物量、成坪时间作为综合质量评定的二级指标,采用层次分析法(AHP),通过构建权重矩阵,对所评价草坪指标配以权重,然后结合模糊数学综合评判方法,确定草坪质量优劣。[结果]脲醛泡沫栽培基质覆土处理草坪综合质量优于未覆土处理及常规处理,F1处理草坪质量综合评价值最高,为0.770。[结论]脲醛泡沫栽培基质能够生产出优质的草坪,可进一步推广利用。

[Objective] The aim of this study was to explore the feasibility of three kinds of urea formaldehyde foam substrate in tall fescue establishment as well as to study on evaluation of turf quality.[Method] The visual estimates,ecological quality estimates and utility quality estimates were used as the 1st level indicators,and the density,color,texture,uniformity,green period,cover degree,biomass,emergence energy,growth rate and turf-forming time were used as the corresponding 2nd level indicators.With T.L.Satty＇s method Analytic Hierarchy Process（AHP） and the fuzzy synthesis evaluation method,the weight ratio of matrix was obtained and the synthetic evaluation result was accorded with facts,then it could be regarded as the satisfying value of weight.[Result] The quality of three soil covering treatments was better than that of uncovering treatment and conventional treatment,the quality synthetic evaluation of F1 was the best,which was about 0.770.[Conclusion] Urea formaldehyde foam substrate showed high quality for turf establishment,which could be further spread and applied.
