韭菜生长的适温为白天１８～２８℃，夜间８～１２℃，冬季靠生产韭黄、韭青的韭田，全靠日光照射提供热量和覆盖保留热量。在其生长适温范围内，随着棚内气温和土温度的升高韭菜生长加快，而冬季往往由于畦内温度低致使韭黄韭青主长缓慢，收割周期拖长。因此，要促进韭黄韭青 Chives growing temperature of 18 ~ 28 ℃ during the day and 8 ~ 12 ℃ at night, by the production of chives in winter, leek green allium, thanks to sunlight and cover the heat to provide coverage. In its growth temperature range, with the shed temperature and soil temperature increased leek growth accelerated, while in winter is often due to the temperature inside the low chives and leeks leading to slow, long cycle of harvesting delay. Therefore, to promote chives and leeks
