摘  要:
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.
