| 摘 要： | 研究了3种不同薄膜覆盖大棚内小气候因子的变化.研究结果表明,在不同测定日期中,覆盖不同塑料薄膜大棚的棚内外日平均气温和日平均地温变化相似,转光膜1的保温性能优于转光膜2和无滴膜;转光膜1的透光率高于转光膜2和无滴膜,无滴膜的透光率则略高于转光膜2.不论晴天还是阴天,转光膜,均表现出较好的保温与采光性能,而且使用这3种农膜后.大棚内温度和光强变化规律相似.

| Abstract: | The changes of microclimate factors in greenhouse covered with three different films were studied. The results showed that the changes of the average temperature and the average soil temperature were similar in greenhouses covered with different films in different dates. The insulation properties of Sunlight -conversion film 1 were better than the Sunlight-conversion film 2 and the No-dip tunnel film. Light transparence comparison of the Sunlight-conversion film 1 are higher than the Sunlight -conversion fi... |
