| Abstract: | A new model of lysimeter was designed, which uses water balance in soil for the determination of plant evapotranspiration, with no or little interference with major field cultivation operations. The drained water was stored in a water tank and the water samples were collected by pressurization or suction method. It indicated that water collecting effect of this lysimeter was evident and sediment content in water was very low by field test of 12 such lysimeters. |
