摘  要：
【目的】研究不同水分处理对三种冷季型草坪草地下生物量及坪用质量的影响,旨在为草坪养护过程中提高水的有效利用率提供理论依据。【方法】通过草坪线性梯度灌溉,应用水量平衡原理,研究水分处理对草坪草地下生物量、根系分布的影响情况,探讨不同水分处理与草坪地下生物量的关系及对地下生物量动态变化、根系空间分布的影响。【结果】三种草坪草地下生物量春季最大,秋季最小,根系主要分布在0～10 cm的土壤层内,占地下生物总量的84.08%～87.18%。三种草坪的坪用质量与根茎比值呈负相关。【结论】不同水分处理对三种草坪草的地下生物量有显著影响,适宜的根茎比能够得到较好的坪用质量。

摘  要：
[Objective]The purpose of this program was to provide a theoretical basis for the effective utilization of water during the lawn conservation process by studying the effect of soil water on the biomass under the three cold - season turfgrass in Xinjiang.[Method]Linear gradient lawn irrigation and water balance principle were applied to study the effects of water treatment on the biomass under the lawn and root biomass distribution to explore the different underground lawn irrigation and the relationship between biomass and underground biomass dynamics,and the impact of the spatial distribution of roots.[Result]The results showed that the biomass under the three cold - season turfgrass was the largest in spring and autumn,and roots were mainly located at the 0-10 cm soil layer.The biomass accounted for 84.08%- 87.18%of the total. The relationship between the three types of lawn turf quality and root ratio was negative.[Conclusion]The different water treatments affected the under - ground biomass of turfgrass significantly,and the appropriate roots can get a better turf quality.
