摘要: 经过对地膜物料结构的深入研究,提出了单向渗水原理,设计并发明了渗水地膜。渗水地膜具有保温、调温、渗水、保水、微通气等多种功能,可使半干旱地区发生频率为70%左右、年累计量为100~150mm的小雨量资源得到开发利用。旱地试验表明:渗水地膜覆盖的粮食作物比常规地膜覆盖的增产157%~383%,比无覆盖的增产1倍以上。

关键词: 渗水地膜, 小雨, 孔隙, 旱地

Abstract: Based on in depth studies of structure of membranes, the principle of water osmosis in single direction was put forward, and water osmotic plastic film was designed and developed. Plastic film of the kind possesses various functions such as temperature preservation, temperature regulation, water percolation, water conservation and micro air ventilation.The tests covered with water osmotic plastic film showed an increase of 15 7%~38 3% in grain yield, 1%~4 5% of increase in soil water over conventional membrane, and double increase in grain yield than no covered.

Key words: water osmotic plastic film, small rainfall, fissure, dry land
