摘要:
为了解红富士苹果叶片蒸腾规律,并为气孔计法提供经验校正系数,采用气孔计法和离体枝条称重法,于2008~2009年在山东省泰安市潮泉镇上寨村(36°15′N,117°06′E),对红富士苹果叶片蒸腾作用进行了连续定位观测,比较了2种方法的不同,提出了采用气孔计法测定红富士苹果叶片蒸腾作用的校正系数.结果表明:气孔计法蒸腾强度测定值恒大于离体枝条称重法测定值,气孔计法测定值为称重法的1.03~4.00倍,平均为2.02倍,整个生长期校正系数为0.495.气孔计法测定的离体枝条(水分供应充足)叶片蒸腾速率是活体叶片蒸腾速率的1.07~3.44倍,平均为1.45倍.%In order to understand the law of leaf transpiration rate in Red Fuji apple and offer a empirical correction coefficient, using porometer method and in-vitro shoots weighing method, continuous located observation of leaf transpiration rate of Red Fuji apple was carried out in Shangzhai Village (36° 15'N, 117°06'E), Chaoquan Town, Tai'an City, Shandong Province, during 2008 to 2009, the two methods were compared, and the correction coefficient of leaf transpiration rate of Red Fuji apple was obtained by using porometer method. The results show that value obtained by using porometer method is constantly larger (0.03-3.00 times with a mean as 1.02 times) than that obtained by using in-vitro shoots weighing method, and the correction coefficient of the whole growing phase is 0.495. Leaf transpiration rate of in-vitro shoots (supplied with sufficient water) measured by porometer method is 1.07-3.44 times (with a mean as 1.45 times) as large as the leaf transpiration rate of living tree.

摘要:
为探讨荒漠化地区不同立地条件下树木适应干旱的能力,研究了章古台沙地主要固沙造林树种的蒸腾强度在不同时期的变化。通过对章古台沙地樟子松、小叶杨的蒸腾强度的研究,发现树种蒸腾强度的大小与树种的抗旱性密切相关。树木蒸腾强度和生理指标的测定结果表明,樟子松的蒸腾强度在不同时期均低于小叶杨。樟子松更适宜在章古台地区栽植。

摘要:
The research took 8 wild grand cover plants in South China as study objects. They were widely distributed in the wild and had ornamental value. Photosynthetic datum were collected in winter and summer, to research on saving benefits by calculation transpirations. The results showed that: for the daily average net photosynthetic rates,Hgdrocotyle Sibthorpoilides, Melastoma dodecandrum,Viola inconspicuahad high value in winter than in summer, and could be excellent winter growing ground cover plants.Alysicarpus vaginalis had high daily average net photosynthetic rate in summer, and its growth was vigorous. From the viewpoint of transpiration characteristics,Melastoma dodecandrum had small total daily transpiration per unit leaf area in winter and summer. In summer, the evaportranspirations per unit greening area per unit time ofMelastoma dodecandrum,Desmodium triflourum,Dichondra repens,Hgdrocotyle Sibthorpoilides,Murdannia loriformis were small, therefore their irrigation volume could be reduced according to the actual situation.%对华南地区野外资源分布较广且具有一定观赏价值的8种野生地被植物进行冬季和夏季的光合数据采集,并通过计算蒸腾强度分析其节水效益。结果显示:天胡荽、地稔和长萼堇菜日平均净光合速率在冬季显著高于夏季,说明它们为冬季生长优良的地被植物;而链荚豆则在夏季的日平均净光合速率较高,生长较为旺盛。从蒸腾耗水特性来看,地稔在冬季和夏季的单位叶面积日蒸腾总量均较小;在夏季单位时间单位绿化面积内,地稔、三点金、马蹄金、天胡荽和牛轭草的蒸腾量较少,可根据实际情况减少灌溉量。

摘要:
利用野外离体快速称重法选取5个主要乔、灌木造林树种进行蒸腾强度的日变化及蒸腾耗水量进行观测和研究.同时,结合小气候因子的同步观测,研究各被调查树种的蒸腾耗水量与小气候的关系.对比研究结果表明:以红松的蒸腾强度为最大0.4300g/g·h-1,其次是落叶松为0.4117g/g·h-1,以榛子的为最小0.2799g/g·h-1,蒸腾强度大小规律为红松>落叶松>樟子松>樟子松幼林>水曲柳>水曲柳幼林>榛子且各树种的蒸腾强度日进程曲线均呈单峰,气温与植物蒸腾强度的有密切的相关性.

摘要:
为了探究北京山区常绿树的耗水规律,利用大型称重式蒸渗仪于2010年对北京西山地区油松蒸腾进行连续高精度的观测,分析油松蒸腾的动态变化,同时结合气象因子的观测数据,分析蒸腾强度与气象因子的相关性,从而定量得到各因子对蒸腾的影响程度.结果表明:油松晴天蒸腾日变化呈单峰曲线趋势,在中午时刻出现最大值,与太阳辐射和气温变化趋势保持一致;阴雨天表现为多峰曲线趋势.在各气象因子中,蒸腾强度(Ti)与大气温度(Ta)、大气相对湿度(RH)、冠层净辐射(Rn)和饱和水汽压差(VPD)的相关性较好,其相关方程为Ti=2.228-0.07 Ta-0.032RH-0.002Rn+1.108VPD.%In order to explore the evapotranspiration of evergreen trees in Beijing Mountainou Area,the dynamic change of Pinus tabuliformis transpiration in the West Mountain Area of Beijing was continuously and high-precision measured in June 2010 using large-scale weighing lysimeter.Combined with the observational data of meteorological factors,the correlation between transpiration intensity and meteorological factors was analyzed.The results showed that:In sunny days,diurnal variation of transpiration of Pinus tabulaeformis showed a single-peak curve trend and the maximum was found at noon,which was in accordance with the solar radiation intensity and the temperature.But in rainy days,it showed the multi-peak curve trend.Transpiration intensity (Ti) was significantly related to atmospheric temperature (Ta),relativeair humidity (RH),canopy net radiation (Rn) and vapor pressure deficit (VPD),the regression equation was Ti =2.228-0.07Ta-0.032RH-0.002Rn + 1.108VPD.
