摘要
针对夏季温室易出现极端高温,不利于作物生长发育的现象,研究不同内遮阳材料对温室的降温效果。结果表明:遮阳材料在不同程度上都有一定的遮光降温保湿作用,且其降温效果与材料的透光率有很大的关系,透光率越低,降温效果越好,保湿性越高。其中降温效果优劣排序为铝箔>双层的确良布>遮阳网>单层的确良布>无材料。
Extreme high-temperature frequently occurred in greenhouse in summer, and it is harmful to crop growth and development. In view of the need of cooling in greenhouse during summer, the four kinds of cover materials were carried out. The results showed that cover materials had the effects of sun-shading, cooling, and keeping moisture to some degree, and the cooling effect was related to transmittance. The lower the light transmission rate, the better the cooling effect. The cooling effects of four kinds of materials followed the order,aluminum roll〉double dacron〉shade net〉single dacron〉without coverage.
