莱州湾地区防治海水入侵灾害的农田生态工程试验研究

针对莱州湾地区面临的干旱缺水、海水入侵严重、土地生产力下降的严峻现状,在莱州和寿光两地进行了以良种选育、结构调整、轮作套种、地膜覆盖、节水灌溉、改土培肥和林农间作等技术为主的农田生态工程试验示范研究,取得了显着生态效益和经济效益。为防治海水入侵灾害,实现农业可持续发展,建立了可供借鉴的典型样板.

Experimentalstudies of farmland ecological engineering on controlling disasters of seawater intrusionin Laizhou Bay.

In view of the serious situations of drought, water shortage, seawater intrusion and land productivity decline in Laizhou Bay area of China, exemplary experimental studies of farmland ecological engineering were carried out in Laizhou and Shouguang. The ecological engineering mainly included the techniques of the selection of improved varieties, crop structure adjustment, rotation and intercropping, plastic film covering , water saving irrigation, soil fertilization and crop tree intercropping, which gave a remarkable ecological and economical benefit. Based on this, the exemplary models on controlling the disaster of seawater intrusion and on realizing the sustainable development of agriculture were set up.
