土壤水分对三种冷季型草坪草地下生物量的影响
The Effect of Soil Water on the Biomass under the Three Cold- season Turfgrass
摘要
Abstract
[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.关键词
