摘要
准确地估算农作物腾发量对于农业节水领域的科学研究具有重要意义。为此,以蒸渗仪法直接测定腾发量为切入点,系统地介绍了非称重式蒸渗仪和称重式蒸渗仪的类型、组成、工作原理及其应用现状,对比分析了几种称重式蒸渗仪的应用特点,并指出小型称重式蒸渗仪的检测精度有待提高。
Accurately measure or estimate the amount of crop evapotranspiration, which is significant to scientific research in the field of agricultural water saving. Based on the direct determination of the amount of crop evapotranspiration, and take Lysimeter method as the breakthrough point. Some weighing and non- weighing types Lysimeter, and their form, working principle, and the status quo of application were introduced systematically. More- over, the advantages and disadvantages of the large and small weighing types Lysimeter were contrast analysed, and researches on small weighing types Lysimeters remains to be further strengthened was pointed out.
