Title: Effects of soaking treatment with earthworm cast and domestic rubbish compost extract on seed germination and seedling growth of turfgrass
Abstract: Seeds of Lolium perenne,Festuca arundinacea and Poa pratensis were soaked with earthworm cast extract,domestic rubbish compost extract and their mixture and then the seed germination and seedling growth were investigated.The results showed that the domestic rubbish compost extract had positive effect on seed germination rate.All extracts,especially the earthworm cast extract,promoted the aboveground biomass accumulation of L.perenne and F.arundinacea.Compared with the control,the aboveground biomass of L.perenne and F.arundinacea were increased by 70.71% and 30.52% respectively.But the extracts had negative effects on the aboveground biomass of P.pratensis.The extracts inhibited root growth and the root weight,root length and ratio of root and shoot of three turfgrasses decreased compared with control.The extracts could increase the content of chlorophyll and promote the photosynthesis and the growth of turfgrasses.
