摘　　要：以天津市3种常见绿化植物国槐、白蜡及海棠为研究对象,分别采用传统漫灌技术、滴灌节水技术、粘土宝根灌节水集成技术3种节水灌溉管理方式,调查分析试验树种的株高、直径、胸径以确定不同灌溉方式对树木生长情况的影响,分析不同灌溉处理对绿化植物健康评价指标和综合健康评价的影响。结果表明,灌溉方式对树高并无显著性影响;滴灌和粘土宝根灌相较于漫灌对照处理有增加植物直径、胸径的趋势,可以良好满足植物正常生长。滴灌和粘土宝根灌均没有对植物健康评价指标和综合健康评价造成显著的影响,并且国槐和海棠2种植物在滴灌和粘土宝根灌方式下健康程度高于漫灌对照。In this study,three common greening plants,Sophora japonica Linn.,Malus spectabilis and Fraxinus chinensis,were selected as research objects at the Liangtou Seedling Base of Jinghai District,Tianjin City.The experiment was conducted over a one-year period,during which time the three kinds of greening plants were irrigated using three different techniques:traditional diffuse irrigation technology,drip irrigation water-saving technology,and clay root irrigation treasure water-saving integrated technology.The height,diameter,and diameter at breast height of the experimental trees were investigated and analysed to determine the effects of different irrigation methods on the growth of the trees.The results demonstrated that there was no significant effect of the irrigation methods on the height of the trees.However,drip irrigation and clay root irrigation treasure exhibited a tendency to increase the diameter and diameter at breast height of the plants compared with the control treatment of diffuse irrigation.This could be attributed to the satisfactory growth of the plants under these treatments.Subsequently,the impact of the implementation of water-saving technologies on the health evaluation indexes and comprehensive health evaluation of greening plants was clarified by measuring and analysing the tree health evaluation indexes under different irrigation treatments.The results demonstrated that neither drip irrigation nor clay treasure root irrigation had a significant impact on plant health evaluation indexes and comprehensive health evaluation.Furthermore,the health degree of the two plants,Sophora japonica Linn.and Fraxinus chinensis,was found to be higher than that of the irrigation control under drip irrigation and clay root irrigation treasure.
