所谓“变温管理”就是在大棚蔬菜生产中，根据蔬菜作物生理活动的昼夜变化及其对温度条件的反应，搞好温度棚内调节，以促进光合作用，抑制呼吸消耗，加速营养物质的运输和积累，以达到增产的目的。据试验结果和生产实践表明，采用变温管理措施，可使黄瓜增产20％，茄子增卢5％ The so-called “variable temperature management” is the greenhouse vegetable production, according to the diurnal changes in the physiological activities of vegetable crops and their response to temperature conditions, do a good job of adjusting the greenhouse shed to promote photosynthesis, respiratory depression, accelerate the transport of nutrients and Accumulation, in order to achieve the purpose of increasing production. According to the test results and production practices show that the use of temperature management measures can increase cucumber yield by 20%, eggplant by Lu 5%
