中文摘要：

为探索华北地区狗牙根草坪建植期养分管理策略,以邯郸狗牙根和保定狗牙根为供试材料,研究了不同用量（0、2、4、8 g/m2）磷肥对狗牙根营养体建坪效果的影响.结果表明,除高磷处理（8 g/m2）显著加快狗牙根匍匐茎生长速度外,施用磷肥能在一定程度上提高草坪盖度和匍匐茎生长速度、增加草屑量、缩短成坪时间、改善草坪色泽,但品种间和品种内处理间均无显著差异.在设置试验条件下,磷对狗牙根营养体建坪的影响不大,这可能与土壤中较高的速效磷含量有关.

英文摘要：

To seek for the optimal nutrition management strategy,the effects of different phosphorous fertilizer rate on vegetative establishment of bermudagrass turf in North China were studied.Application of higher phosphorous fertilizer （8 g/m2） significantly enhanced the growth rate of bermudagrass stolons.Although application of phosphorous fertilizer improved turf coverage and color and reduced the time of establishment in certain degree,there was no significantly difference among the treatments and between the cultivars.This indicated that phosphorous had little effect on vegetative establishment of bermudagrass turf,which may be related to the higher content of available phosphorous in the tested soil.
