【Objective】 Polypropylene microplastics are fragments of polypropylene. They exist in soil and have potential impact on soil environment. This paper investigates their influence on water flow and salt redistribution in soil under drip irrigation. 【Method】 The experiment was conducted in cuboid tanks packed by saline soil. Steady water infiltration into the soil was maintained by a Martensian flask; the infiltration rate was controlled at 0.36 L/h by a rotameter. The content of polypropylene microplastics in the soil was 2%, and the salt content was 0.5%, 4% or 7%. 【Result】 Soil water content and initial soil salt content were positively correlated. The average water content in the soil with initial salt content of 7.0% was 9.4% and 11.2% higher than that in soils with initial salt contents of 4.0% and 0.5%, respectively (P |
