浙江冬季大棚不同覆盖方式保温效果研究

Effects of Different Mulching Methods on Warmth Preservation through Winter Cultivation in Zhejiang

比较了农膜不同覆盖层数、不同保温材料及覆盖方法对南方单体大棚的冬季保温效果。研究结果表明,在台州黄岩区气候条件下,低温期间大棚采用三膜覆盖,一般可提高棚内最低温度5℃以上;在强冷空气影响时,棚外再加盖一层遮阳网并在大棚两头进行套膜处理,可保植株免受零下6~7℃极端低温天气伤害。

This investigation was conducted to compare the effects of different mulching methods on warmth preservation of winter cultivation.The results showed that the temperature inside the single plastic house was increased more than 5℃ when covered with three layers of plastic films.In extreme low temperature,three-layer mulching plus top sunshade and intensive mulching on two gates were able to save plants from being injured at minus 6-7℃.
