采用撒茎覆盖法、开沟植茎法、栽植法和撒茎镇压法4 种方式建植兰引 3 号结缕草(Zoysia j aponica 'Lanyin No.Ⅲ')无土草皮,通过观测草皮生长过程中坪用性状,分析不同建植方式对草皮质量的影响,以期为兰引3号结缕草无土草皮生产提供技术参考.结果表明,撒茎覆盖法的盖度为93.67%、密度为9844株?m—2、均一性8.17、色泽7.6、生长速度4.63 mm?d—1、草屑生物量38.91 g?m—2均高于其余3种建植方式,且整体表现为撒茎覆盖法>栽植法>撒茎镇压法>开沟植茎法.综合分析认为,撒茎覆盖法适合兰引3号结缕草无土草皮生产,而开沟植茎法成坪慢、盖度低,均一性较差,不适合作为兰引3号结缕草无土草皮的建植方式.%The experiment to produce soilless sod of Lanyin No.Ⅲ zoysia grass was carried out using four plant-ing methods,including stolonizing + topdressing,stolonizing in-furrow,sprigging,and stolonizing + rolling. The sod quality with different planting methods was studied by investigating turf characteristics during the sod establishment so as to provide the technical reference for the soilless sod production of Lanyin No.Ⅲ zoysia grass.The results showed that coverage,density,uniformity,color,growth speed,and clipping biomass with the method of stolonizing + topdressing were 93.67%,9 844 plants?m—2,8.17,7.6,4.63 mm?d—1,and 38. 9 1 g?m—2,respectively,which were higher than those of the other three planting methods.The overall sod quality was ranked as stolonizing + topdressing > sprigging > stolonizing + rolling > stolonizing in-furrow. Based on comprehensive analysis of the results,it was considered that stolonizing + topdressing was a suitable planting method for the soilless sod production of Lanyin No.Ⅲ zoysia grass,whereas stolonizing in-furrow was not good due to the slower growth speed,lower coverage,and poor uniformity during the establishment of sod.
