摘要
为解决天津滨海地区园林树木耗水量大的问题,该研究以该地区常见的园林树木为材料进行了灌溉制度方面的研究.该实验是把水分作为单因子的完全随机区组设计,以中子水分仪作为土壤水分测量工具,研究了5—10月洋白蜡和金银木在天津滨海地区特殊土壤条件下的土壤水分动态及其植物形态指标,并制定了相应的灌溉制度,包括灌水饱和点、灌水补偿点、计划湿润深度、灌水定额、灌溉周期和灌溉定额,其中洋白蜡灌溉定额525mm、灌溉次数7次;金银木灌溉定额350mm、灌溉次数10次.
In order to solve the problem of high water consumption volume by garden plants in Tianjin coastal region, this study focused on the irrigation schedule of most common garden plants in this area. The study was carried out by randomizing block experiment design and the single factor experimental technique and used neutron probe to measure the soil moisture. Based on the study of soil moisture dynamics and plant growth about Fraxinus pennsylvanica and Lonicera maackii in Tianjin seaside region, the irrigation...
