摘　　要：研究了蚓粪作为草坪草坪床基质改良剂对基质理化性状和草坪草生长的影响,以确定蚓粪作为坪床基质改良剂的可行性。在砂中添加20、40、60、80和100 g.kg-1蚓粪作为坪床基质,并与添加40 g.kg-1泥炭的坪床基质进行比较,结果表明,添加蚓粪可使基质pH值下降,电导率σ值明显增加,100 g.kg-1蚓粪处理σ值比对照(未添加蚓粪或泥炭)提高了约16倍,但成坪后基质σ值明显下降,并与对照接近。添加蚓粪能够明显改良坪床基质,有利于草坪草的生长。与40 g.kg-1泥炭处理相比,添加40、60、80和100 g.kg-1蚓粪处理的草坪成坪时间更短,草坪颜色较深,叶片变宽,再生速度快。蚓粪可作为一种良好的坪床基质改良剂,在20、40、60、80和100 g.kg-1蚓粪添加量条件下,蚓粪添加量越高,其对基质的改良效果越明显,但在实际应用中应注意因蚓粪含磷量较高而可能带来草坪草后期长势过快的问题。Influence on the properties of turf-bed and growth of creeping bentgrass based on cow-manure-vermicompost as the basic materials were studied to determine the feasibility and effectiveness of cow-manure-vermicompost as substrate modifier of the turf-bed.The results show that pH value of the turf-bed decreased with an increasing addition of vermicompost while conductivity（σ） value remarkably increased.Conductivity value in 100 g·kg-1 vermicompost treatment was about 16 times of that in CK.But after the turf establishment stage,conductivity values decreased to the level close to that of CK.Compared with addition of 40 g·kg-1 peat,the addition of 40,60,80 and 100 g·kg-1 vermicompost can significantly shorten the time of the formation process of the lawn,considerably increase the regeneration speed,and remarkably improve the chlorophyll content and the clipping content.The growth of grass in vermicompost treatments was better than that in peat treatment.During actual performance,it should be considered that the growth of grass may be too fast at the later stage due to the higher content of phosphorus in vermicompost.
