树木的蒸腾耗水量是植树造林设计与环境水分研究的重要水分参数,它是一个复杂的生理学与物理学过程。采用不同的根系保水措施,定量研究了人工栽植黑松的日耗水量以及水分蒸散差异规律,结果表明在充分灌水条件下,苗木日平均耗水在0.004 93 kg(7月中旬以后),并且保持持续地稳定失水;秸秆造林与保水剂造林在持续干旱36d条件下持续供水能力强,维持其生长状况的能力分别是无措施条件下的3.66倍和7.31倍。
The transpiration water consumption of trees is an important moisture parameter for afforestation design and environmental moisture research. It is a complex physiological and physical process. Using different water conservation measures, the daily water consumption and the law of evapotranspiration of artificial planted black pine were studied quantitatively. The results showed that the average daily water consumption of seedlings was 0.004 93 kg (after mid July) under the condition of sufficient irrigation, Stable waterlogging afforestation and water retention agent afforestation in the continuous drought 36d continuous water supply capacity, ability to maintain their growth conditions were 3.66 times and 7.31 times without measures.
