稻田由于地下水位过高或耕层长期滞水,使土壤水多气少,水、肥、气、热失调。并伴有过量的毒害物质,产生渍害,危害水稻正常生长,影响产量。水稻是我省的主产作物,近年来稻田渍害已成为影响我省水稻增产的障碍性因素之一,且渍害面积尚有继续扩大之趋势。因此,寻求有效的治渍措施是水稻生产中一项急待解决的问题,这对于保护和开发利用我省土地资源、发展粮食生产,具有深远的意义。我们于1982年选择了我省上高县东边大队渍害稻田为技术治理的中间试验区,进行了以地下排水为中心的水利措施治理试验。其目的主要是探索治理渍害稻田地下排水工程的合理布局及其效应,为治理渍害稻田地下排水工程的规划设计及生产应用方面提 Due to the high groundwater table in paddy fields or long-term stagnant topsoil, the soil has little water and more water, water, fertilizer, air and heat. Accompanied by excessive toxic substances, resulting in waterlogging, endangering the normal growth of rice, affecting the yield. Rice is the main crop of our province. In recent years, waterlogging in rice fields has become one of the obstacle factors affecting rice yield in our province, and the area of ​​waterlogging stains continues to expand. Therefore, it is of great significance to seek effective measures to control soil erosion in rice production. This is of far-reaching significance for the protection and exploitation of land resources in our province and the development of food production. In 1982, we selected the pilot area where the east brigade of Shanggao County in our province wiped out paddy fields for technical control and conducted experiments on harnessing water conservancy measures centered on underground drainage. Its main purpose is to explore the rational distribution and its effect of underground drainage works for treating paddy soils, in order to improve the planning, design and production and application of the underground drainage works of paddy soils
