摘要：

The influence of irrigation with leachate on biomass production and evapotranspiration was studied on three sanitary landfills in southern Finland in 1982 - 1984. Irrigation with leachate increased biomass production significantly. The quality of the irrigation water and substrate, mode of irrigation and tree species also influenced biomass production. In a willow stand, 30% of the irrigation and precipitation was intercepted. Evapotranspiration calculations based on biomass production measurements, water consumption per unit dry matter produced and interception measurements gave results similar to the values obtained with the Penman - Monteith equation. Irrigation with leachate was found to increase evapotranspiration on a sanitary landfill. The evapotranspiration of the mini-rotation plantations during the growing season amounted to 600-700 mm.
