采用四段变温管理，即揭棉被—13：00、13：00—盖棉被、盖棉被—19：00、19：00—次日揭棉被，以贝美番茄和津早一号黄瓜为材料，研究了冬季温室气温调控对其生长的影响。研究结果表明，在冬季温室生产中，采用透光率较高的PO膜覆盖和适当较高的四段变温管理，即4个时间段下番茄和黄瓜的温度指标分别为26℃—24℃—18℃—12℃和28℃—25℃—19℃—13℃时，更有利于番茄和黄瓜植株生长，株高、茎粗、叶面积的相对生长量增加，坐果率和果实膨大速度增加，叶片叶绿素含量增加及净光合速率增强。

Taking tomato cultivar Beimei and cucumber cultivar Jinzao No.1 as materials and adopting the four-section variable temperature treatment (uncovering quilts-13:00-covering quilts-19:00-uncovering quilts), we studied the effects of different temperatures on the growth of tomato and cucumber in winter greenhouse. The results showed that, during the production in winter greenhouse, when covered PO film with high light transmittance on the greenhouses, the suitable temperature indexes of four-section variable temperature treatments for tomato and cucumber were 26℃-24℃-18℃-12℃and 28℃-25℃-19℃-13℃ respectively, which promoted the growth of tomato and cucumber, and increased relative growth of plant height, stem diameter and leaf area, fruit-setting rate, fruit enlargement speed, chlorophyll content and net photosynthetic rate as well.
