从栽培角度看支配蔬菜生育最重要的条件是温度。当温度条件满足不了蔬菜的要求时,相应的光照、水分、养分等条件就不能充分发挥作用。因此,温室大棚中的温度管理,就成了极其重要的技术。 果菜的生育适温因蔬菜种类、品种、生育阶段、光照强度(季节和天气)、湿度和CO_2浓度,以及昼夜不同生理活动重心过程而变化。其保护地栽培的温度管理应依其适温要求进行变温管理和综合调控,并
The most important condition that governs vegetable fertility from the cultivation point of view is temperature. When the temperature conditions can not meet the requirements of vegetables, the corresponding light, moisture, nutrients and other conditions can not fully play its role. Therefore, the temperature management in the greenhouse has become an extremely important technology. Fruit and vegetable fertility temperature due to vegetable species, variety, stage of growth, light intensity (seasons and weather), humidity and CO 2 concentration, as well as diurnal changes in the center of gravity of different physiological activities. The protective cultivation temperature management should be based on its temperature requirements for temperature management and integrated control, and
