【摘要】 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。更多还原

【Abstract】 Trees’evapotranspiration is the important moisture parameter of afforestation design and environment moisture inves- tigation,and also is a complex process of physiology and physics.A quantitative study on water consumption of the black pine planting as well as the differences of moisture evaporation is carried out under different condition.The results show that the av- erage water consumption of seedlings is 0.004 93 kg(after mid-July)in the full irrigation,and continued to maintain stable wa- ter loss.Straw stalk afforestation and water retaining agent afforestation maintained a strong ability of water supplement under 36-day continuous drought condition,and maintaining its capacity growth is 3.66 and 7.31 times of non-measure condition re- spectively.更多还原
