以生活垃圾堆肥为基质的废弃物铺网草皮建植研究

Turf Established by Sod with Municipal Solid Waste Compost as Medium and Waste Materials as Netting

以生活垃圾堆肥为基质,5种生活废弃物为铺网,对高羊茅、草地早熟禾及本特3种草坪植物的草皮培植与铺坪应用进行了研究.结果表明:(1)在草皮培植中,同种草坪植物在不同铺网草皮中的生长效应差异较大,其中早熟禾在草席与塑料纱网草皮中的综合性能表现较好;本特和高羊茅在竹席和草席中的表现较好.(2)草皮的刈割再生生长能力总体上与草皮培植时的生长状况密切相关,草种与基质、铺网间的协同性存在差异,生长协同性较好的草皮组合为早熟禾的草席草皮、本特的草席与塑料纱网草皮以及高羊茅的草席、纤维网袋与塑料纱网草皮.(3)5种生活废弃物铺网中,塑料薄膜在草皮培植中与各草种间的协同性均最差,其铺网草皮在铺坪应用中的再生生长能力也较差,可见塑料薄膜不适宜作为草皮铺网.

Research was conducted to investigate sod culture and sod laying of three kinds of turfgrasses by using municipal solid waste compost as medium and 5 waste materials （fibrous woven sack,plastic window gauze,plastic film,bamboo mat and straw mat） as netting. The results showed that （1） in sod culture, there were significant differences in growth effect of turfgrass among different netting sods with the same turfgrass. Among which, sods with straw mat and plastic window gauze for Poa pratensis L. , and sods with bamboo mat and straw mat for Agrostis stolonifera L. and Festuca arundinacea L. showed better performances respectively than the other sods did. （2） The regrowth ability of sods after mowing was closely correlated with the growth situation of sods in sod laying. There were differences in cooperativity of cultivar, medium and netting. Straw mat sod for P. pratensis,straw mat and plastic window gauze sods for A. stolonifera,straw mat, fibrous woven sack and plastic window gauze sods F. arundinacea achieved better results in cooperativity of growth. （3） Among the 5 nettings of waste materials,plastic film had the worst cooperativity with 3 kinds of turfgrasses. Also plastic film sods showed relatively weak regrowth ability after sod laying. So plastic film was not suitable for sod netting.
