饱和土栽培是一种连续灌溉、保持恒定水深、使土层处于饱和状态的栽培技术。该技术适用于防止潮滩湿地上黄铁矿氧化，提高潮滩湿地大豆产量。研究了饱和土壤培养条件下淹水对大豆生长和产量的影响。实验于5月至9月在南苏门答腊省Banyuasin区丹戎湖分区Mulyasari村（海拔11英尺，南纬2°38'42.35“，东经104° 45' 5.92”）进行。试验采用裂区设计，重复三次。主要试验区为淹水条件，包括：1）从种植到收获时间的连续饱和土壤条件（作为对照），和2）0-10 DAP（种植后天数）的饱和土壤条件+11-13 DAP的淹水+14-28 DAP的饱和土壤条件+29-31 DAP的淹水+32 DAP的饱和土壤条件直到收获时间。亚区为变种，由Tanggamus、Anjasmoro、Wilis、Detem-2和Malika组成。在饱和土培上进行灌溉，水深为土壤表面以下20 cm，并在土壤表面上方5 cm处进行临时淹没。结果表明，唐加末、安茉莉、德特姆2号为感病品种，威利斯、马利卡为中耐品种。
Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. This technology is appropriate to prevent pyrite oxidation on tidal swamp and has been proved to increase the soybean productivity on tidal swamp. The objective of the research was to study the effect of temporary flooding under saturated soil culture on the growth and productivity of soybean. The experiment was conducted at Mulyasari Village, Tanjung Lago Sub District, Banyuasin District, South Sumatra Province (11 feet above sea level, 2°38’42.35 “South Latitude, and 104°45’5.92” East Longitude), from May to September. The experiment used a split plot design with three replications. The main plot is flooding condition, consisted of: 1) saturated soil condition continuously, from planting until harvesting time (as control), and 2) saturated soil condition from 0-10 DAP (Days after Planting) + flooding from 11-13 DAP + saturated soil condition from 14-28 DAP + flooding from 29-31 DAP + saturated soil condition from 32 DAP until harvesting time. The sub plot is variety, consisted of: Tanggamus, Anjasmoro, Wilis, Detam-2, and Malika. Irrigation on saturated soil culture was made with water depth 20 cm under soil surface, and temporary flooding was made with 5 cm upper soil surface. The result showed that Tanggamus, Anjasmoro, and Detam-2 were grouped as sensitive variety, while Wilis, and Malika were grouped as moderate-tolerant variety.
