Abstract：To study diferent nitrogen application levels onthe growth and nitrogenand phosphorus nutrient des tinationina stitched hybrid turf，in this study we used tallfescue（Festuca arundinacea） variety‘crossfireIV’ as the test material，and set the nitrogen level treatments of 1g⋅m^-2 ， 3g⋅m^-2 ， 5g⋅m^-2 and 7g⋅m^-2 ，and no nitrogen treatment was used as control. The efects of nitrogen application levels on the turf quality，growth rate and biomass of stitched hybrid turf，the absorption of nitrogen and phosphorus nutrients，the residues of nitrogen and phosphorus nutrients in soil and the leaching losses of nitrogen and phosphorus nutrients were measured.The results showed that with the increase of nitrogen application rate，the improvement of turf quality was greater in 1-2 months after turfformation.However，in the third month，the high nitrogen treatment group （ 5g⋅m^-2 and 7g⋅m^-2 per month） significantly accelerated the growth rate of turf grass，but also led to the excessive growth of turf. Under the condition of 3g⋅m^-2 nitrogen application per month， the coverage，density，NDVI，color of turf grassand turfgrass verdure dry weight were the highest.The underground biomass of turfgrass was decreased under high nitrogen application，and the root dry weight of 10-20cm in turfgrass under nitrogen application per 3g⋅m^-2 was increased by 63.2% and 189.9% compared with 5g⋅m^-2 and 7g⋅m^-2 respectively.With the increase of nitrogen application level，nitrogen and phosphorus uptake of turf grass increased，nitrogen residue in soil increased，nitrogen leaching loss also increased，but nitrogen use effciency decreased. When the monthly nitrogen application rate was greater than or equal to 5g⋅m^-2 ，the total nitrogen leaching amount of lawn increased significantly，and the monthly nitrogen application rate of 5g⋅m^-2 and 7g⋅m^-2 increased by 250% and 650% compared with 3g⋅m^-2 ，respectively. The nitrogen uses efficiency of turf decreased significantly，and the monthly nitrogen application of 5g⋅m^-2 and 7g⋅m^-2 decreased by 12.4% and 24.0% ，respectively， compared with that of 3g⋅m^-2 . There was no significant effect on phosphorus residue and leaching in turf soil under diffrent nitrogen application treatments.Therefore，it is recommended to apply about 3g⋅m^-2 nitrogen per month to a stitched hybrid turf.

混合草坪是指由天然草和人造材料混合建植而成的草坪系统1]。植丝式混合草坪是使用专门的机械将人造草丝按一定密度和深度垂直植入草坪根系层而建植的一种混合草坪，它结合了天然草坪与人造草坪的优点。植入人造纤维草丝后，根系层形成了一条条通气透水微通道，草坪草在生长过程中，根系会缠绕人造草丝生长，提高了草坪的稳定性[3]，延长了草坪的使用时间[4-5]。植丝式混合草坪已应用于多届世界杯、欧洲杯等大型足球赛事中，并已成为国际专业足球俱乐部草坪建造的“标配\"技术[6]。

有关植丝式混合草坪的研究多集中于植丝后坪床状况、质量评价以及技术的扩展应用。Anderson等研究发现，植丝式混合草坪抗剪切性能和稳定性均优于纯天然草坪。相关研究表明，植丝后对草坪生长及坪床物理性状有显著影响，植丝后，促进了草坪地上部和地下部的生长，土壤紧实度增加[8-12]。Thanheiser等[13]研究发现植丝式混合草坪表面硬度高于纯天然草坪，并且发现植丝能提高草坪的反弹率。具体而言，使用纯天然草坪的球场足球反弹率为 56% ，而使用植丝式混合草坪的球场足球的反弹率高达 77% 。

然而，关于植丝式混合草坪养分管理方面的研究鲜见报道。已有研究发现，植丝促进了草坪生长，提高了草坪氮素和磷素养分利用效率，降低了草坪氮素淋溶风险[14]。……
