| 【Objective】 Paved natural-synthetic hybrid turf is a kind of newly developed hybrid turf in recent
years. The synthetic grass of this hybrid turf is woven, and the natural grass is mostly planted by seeding. By comparing and
evaluating the planting effect of perennial ryegrass, Kentucky bluegrass and tall fescue in paved natural-synthetic hybrid
turf, the study was aimed to provide technical reference for the establishment of paved hybrid turf.【Method】 The perennial
ryegrass, kentucky bluegrass and tall fescue were planted on paved synthetic turf with seeding rates of 40 g/m2, 20 g/m2 and
40 g/m2 to establish hybrid turf. And the comprehensive evaluation of characteristics and quality of the three kinds of hybrid
turfs were conducted.【Result】 The results showed that the three cold season turfgrass are all suitable for the establishment
of hybrid turfs. Based on comprehensive evaluation results, the fitness was ranked as perennial ryegrass ＞ tall fescue ＞
kentucky bluegrass, indicating that perennial ryegrass is the best one as natural turfgrass to be used for the establishment of
hybrid turf with 14 d of turf establishment time and 2.77 shoots/cm2 of natural grass density, 4.72 shoots/cm2 of total density,
100% of both natural grass coverage and total coverage, 6.89 points of uniformity score, 12.57 g of plant biomass, and 8.04
points of weighted score at the end of the experiment. 【Conclusion】 According to the results of comprehensive evaluation,
perennial ryegrass is the first choice for the establishment of hybrid turf in north temperate zone. |
