| 摘 要： | 应用热脉冲对河套灌区农田防护小美旱杨（Populus popular’s）日蒸腾耗水量进行了研究。结果表明：在正常生长状态下，小美旱杨的日蒸腾耗水量变化曲线呈宽峰状，随着林龄增加，日蒸腾耗水量逐渐增加，在不同水分条件下,灌水时日蒸腾耗水量：萌生苗日蒸腾耗水量大于扦插日蒸腾耗水量。 |

| Abstract: | The heat-pulse technique was applied to study the transpirationwater consumption of Populus popular in May and June of 1998.The results showed that,in the natural conditions,the intensity of sapflow of Populus popular was 0.088 L.cm-2.d-1,the change curves of the transpiration water consumption are broad peak,at noon it reached the maximum.The transpiration water consumption is increased with age of stand increase.In the different soil moisture content conditions,the transpiration water consumption of Populus popular is higher irrigated than non-irrigated.The transpiration water consumption of sprouted seedling was higher than cuttaged seedling. |
| Keywords: | heat-pulse technique transpiration water consumption Populus popular |
