摘要:
在自然条件下采用盆栽方法，用LI1600和SL20K天平对8种苗木的瞬时蒸腾速率和实际耗水速率进行了比较测定。结果发现火炬树耗水速率峰值最大为56.5g·h-1，杏最小只有30.5 g·h-1，日耗水量的大小顺序为火炬树＞绿宝石＞婆枣＞冬枣＞核桃＞花椒＞黄冠梨＞杏，白天耗水量占日总耗水量的93.8%98.0%；8种苗木的蒸腾速率大小顺序虽然与耗水速率结果基本一致，但它们之间数值差别较大，如黄冠梨的耗水速率测定结果是蒸腾速率测定结果的3. 77倍，最小的也达到1.65倍（火炬树）；除花椒外，7个树种的蒸腾速率与光合有效辐射均达到了0.01水平或0.05水平的显著相关，除花椒和冬枣外，各树种的回归效果较好，特别是火炬树、杏、核桃，R2均在80%以上；但耗水速率与各气象因子之间的相关性稍差，回归效果也不太理想。
Abstract:
In the natural conditions, instant transpiration rate and actual water consumption rate of 8 tree species in the "Green for Grain Project" areas were determined comparatively by LI1600 poprometer and SL20K（20 000g/1g）balance scale with pot tests, results showed that water consumption rate of Rhus typhina was the biggest, which was 56.5g·h-1, while Prunus armenica was the smallest, which was 30.5 g·h-1.Sequence of water consumption per day was Rhus typhin＞Lvbaoshi＞Pozao＞Dongzao＞Juglans regia＞Zanthoxylum bungeanum＞Huangguan＞Prunus sibirica. Water consumption occurred mainly in the day, which reached 93.8%98.0%. Sequence of 8 trees water consumption was consistent with consumption rate, but their values are significantly different such as Huangguan, the rate of water consumption was 3.77 times more than the rate of transpiration. The smallest was 1.65 times(Rhus typhina), except for Zanthoxylum bungeanum, the transpiration rates of 7 tree species were correlated obviously with photosynthetically active radiation at the levels of 0.01 and 0.05. Except for Zanthoxylum bungeanum and Dongzao, other trees regression effects were better. R2 of Rhus typhin, Prunus sibirica and Juglans regia were more than 80%, correlation between consumption rate and some weather factors was poor, so was regression effects.
