摘　　要：冷浸田水稻全程地膜覆盖湿润栽培 ,具有增温、保肥、节水、灭草等改善冷浸田土壤理化性状的综合作用 ,为水稻正常生长发育创造了良好的生态环境。冷浸田由于采取排水覆盖地膜 ,协调了土壤水、热、气、肥等因素 ,从而促进了水稻早生快发 ,有效穗、每穗实粒数增多 ,大幅度提高水稻的单产。水稻覆膜栽培比常规水层栽培增产 11.1%～ 32 .2 %。Rice humid planting technique with plastic mulching in whole life time in cold water paddy field improved soil physically and chemically: increased temperature, kept fertilizer, saved water, killed weed etc. It created favorable ecological environment for rice growing. Due to draining and covering with film in cold water paddy field, it adjusted water with heat, gas and fertility of the soil, so it accelerated rice early and rapidly growing. The effective spikes, available grains per ear and yield were all significantly increased. Rice yield, increased from 11.1% to 32.2% comparing with conventional planting.
