摘　　要：水稻覆膜直播湿润栽培技术是一项减轻劳动强度、节水、降耗、增效的新技术。为了使这一成果尽快转化为现实生产力,我们本着边试验、边示范的策略,2004年在全市多点示范102.13hm2,平均每公顷产量7528.5kg,比常规淹水栽培、覆膜插秧栽培分别增产1968.0kg和586.5kg,增幅达到35.4%和8.4%。着重分析增产节本机理,指明栽培应该注意的问题及展望技术发展方向。As a new technique, plastic-film mulching wet cultivation of paddy-rice could not only alleviate labor intensity, but also achieve a range of effects such as saving water, reducing cost and increasing profit. In order to transform this outcome into real productivity promptly,the writer had made experiment and demonstration simultaneously in several places of the city in 2004 and total area was about 102.13hm^2. As a result, the average yield was 7528.5kg·hm^2,increasing 1968kg·hm^2 and 586.5kg·hm^2 than routine inundation cultivation and transplanting rice-seedlings cultivation respectivly,increasing rate were 35.4% and 8.4% respectively. This article also analysed principles of increasing yields and saving costs,pointed out important problems and developing trends of this technique.
