农田渍害是制约嘉湖平原农业综合经营及作物高产的重要因素。农田渍害形成的外因是地势低洼、降雨集中、排水不畅、地下水位高等；其内因是土壤颗粒匀细、粘闭持水，通气孔隙少、无效孔隙多、土壤长期处于饱和含水量至田间持水量之间等因素。通过总结、归纳，试拟嘉湖平原渍害田的８项指标及针对性的治理措施 Farmland waterlogging is an important factor restricting the integrated management of agriculture in the Jiahu Plain and the high yield of crops. The external causes for the formation of farmland waterlogging are low lying, concentrated rainfall, poor drainage and high underground water level. The internal factors are that the soil particles are fine and sticky, the pores are small and have no effective pores. The soil is saturated with water for a long time to the field Holding water and other factors. By summarizing, inducing and trying out the eight indicators and the corresponding control measures
