不同繁殖方式对匍匐翦股颖草坪质量及生产成本的影响

Effects of different propagation modes on turf quality and operating costs of Agrostis stolonifera

通过枝条繁殖和丛芽繁殖方式扩繁匍匐翦股颖(Agrostis stolonifera L.)草坪,对两种繁殖方式下匍匐翦股颖草坪的成坪效果及生产成本进行了比较研究.结果表明,匍匐翦股颖通过枝条繁殖方式进行扩繁的草坪成坪质量较好,成坪时间较短,生长速度较快,而且草坪颜色、均匀度、密度等也优于丛芽繁殖方式.枝条繁殖方式在60 d内草坪密度达到200枝/100 cm2,而丛芽繁殖则需要70 d以上;草坪盖度达到90%时,枝条繁殖方式比丛芽繁殖方式短10 d左右.枝条繁殖方式使用剪草机械剪切匍匐翦股颖的地上枝条进行扩繁,可以节省大量人工,减少了人力成本,而且可以不破坏原种源草坪,是比较理想的一种营养繁殖方式.

Two different propagation modes,stolon propagating method and root transplanting method,with respect to establishing Agrostis stolonifera L.turf were compared to study the effects of propagation modes on turf quality and operating costs.The results showed that the turf quality,color,density and uniformity were better by using stolon propagating method than that by using root transplanting method.The turf density of Agrostis stolonifera could reach 200 twigs/10 cm×10 cm in 60 days by stolon propagating method,while it would need 70 days to get the same condition by transplanting root method.It could shorten about 10 days by the first method to reach 90% coverage rate of Agrostis stolonifera turf.Stolon propagating method could economize much work and money when mowing the stolon of A.Stolonifera,at the same time,it could save the old turf.Therefore the sotlon propagating method was a perfect way to establish Agrostis stolonifera turf.
