摘　　要：彩叶草越冬场所10℃以下会落叶,停止生长,5℃以下会发生冷害,引起软腐。越冬母株往往因疏于管理,不能安全越冬。为解决彩叶草育苗技术的高能耗现状,为栽培者提供一种低成本越冬技术,本文从热水源、自动补水装置、多层育苗装置和调温技术等方面进行了节能越冬栽培研究,以水为媒介,利用热容量最大的水调节热容量最小的空气,实现了以水修根、以水养根、以水调温、调肥、调气,结果表明:只有保持棚温与维持一定水位才能达到彩叶草越冬育苗的最佳效果。In wintering places, colorful grass leaves below 10˚C and stops growing, while chilling injury occurs below 5˚C, causing soft rot. Overwintering mother plants often fail to overwinter safely due to neglect of management. In order to solve the current situation of high energy consumption and provide a low-cost overwintering technology for the cultivators, this paper studies the energy-saving overwintering cultivation from hot water source, automatic water supplement device, multi-layer seedling device and temperature adjustment technology. With water as the medium, the water with the largest heat capacity is used to adjust the air with the smallest heat capacity, so as to realize root pruning, root cultivation, temperature adjustment, fertilizer adjustment and gas adjustment with water. The results show that only the shed temperature and a certain water level can be maintained.
