水分与草坪质量关系研究进展

A review of the relationship between water and turf quality

随着水资源短缺问题的日趋严重,在城市绿地上如何经济合理地利用水资源成为研究的一个重点问题。现今城市草坪面积不断增长,其用水问题也就成为人们关心的问题。水分影响草坪草的生长,水分与草坪质量有着密切的关系。在研究草坪质量与水分关系时,草坪质量的评价是至关重要的。草坪质量是对草坪优劣程度的一种评价,目前草坪质量评价方法众多,但缺少准确、简单、易行的方法。在对水分与草坪质量关系的研究上,目前只有定性的水分对草坪质量的影响,没有研究水分与草坪质量之间的定量关系。综述了草坪质量评价及其与水分关系的研究进展,目的是提出草坪质量与水分的函数关系,从而根据草坪质量要求来确定最佳的水分投入量。

How to make good use of water resources becomes a key issue in lawns management because shortage of water resources. With the increase of lawns area, saving water has been paid more attention to in rheir management, Water influences the growth of turfgrass, which shows a close relation between water and turf quality. Turf quality is an indicator to evaluate on beauty and healthiness of turf. Currently, there are many methods for evaluating turf quality, but are inaccurate and complex. The relationships between water and turf quality are analyzed but not quantified. This paper reviews the progress of turfgrass quality evaluation and the relationship between turfgrass quality and water and propose a functional equation to describe relationship between turfgrass quality and water in order to optimize quantity of water wanted, which is response to turfgrass quality.
