干旱地区草坪的水分管理

草坪建设是人们对生态环境、休闲健身的要求 ,是生活水准提高的重要标志。在干旱地区建设草坪具有与其它地区所不同的特点和要求 ,主要表现在冷季型草种播种、蒸发强烈、夏季需水量大、有防尘淋洗需水量和冬灌要求。从水量平衡原理出发 ,以节水型草坪建设为目标 ,提出了干旱地区草坪坪床土壤水分平衡模型 ,并根据干旱地区草坪水分管理特点 ,应用坪床土壤水分平衡模型制定了草坪水分管理的一般性策略和不同类型草坪的水分制管理模式。

Water Management of Turf in Arid Region

To establish lawn is a need for good environment, leisure and healthy activities, and is an important indicator of high living standard. The characteristics that distinguish the lawn in arid region from others are seeding with cold-season turfgrass species and watermy more due to strong evapotranspiration in summer, cleaning the grass in spring and irrigating in early winter. In this paper, a soil water balance model for turf bed layer was presented on the basis of the principle of soil water balance and the target of producing water saving lawn. According to the turf bed soil water model and the specific requirements for turf water management, some water management strategies for lawn in arid region were proposed.
