为了消减冷浸型中低产田长期浸渍、还原性物质毒害、有效养分低等障碍因子，通过田间小区试验和动态取样与室内测定，研究了不同栽培和灌溉方式对冷浸田还原性物质及水稻生长的影响。结果表明：与常规栽培灌溉比较，起垄栽培湿润灌溉的土壤活性还原物质含量和亚铁含量分别降低21.9％和18.2％，早稻分蘖数增加25％，叶绿素总量增加38％，根系活力提高75％，产量增加10.8％。起垄栽培结合湿润灌溉方式是适合冷浸田早稻增产的农水管理措施。

The rice yield was poor in cold spring paddy soils because of flooding ,high content of soil deoxidized materials and low soil available nutrient.The effect of different tillage and irrigation modes on soil properties and rice yield were re-searched.The results showed that compared with conventional tillage and irrigation mode ,combination of bed-planting and wet irrigation reduced soil deoxidized materials and ferrous ion content by 21.9%and 18.2%respectively ,increased rice tillering and chlorophyll content by 25% and 38% respectively,promoted root activity and early rice yield by 75% and 10.8%respectively.Combination of bed -planting and wet irrigation was suitable for increasing early rice yield in cold spring paddy soil.
