温室黄瓜四段变温管理是根据黄瓜自身的生物学特性和一天内生理活动中心的转移规律制定的一种新的栽培管理措施。它将一昼夜划分成四个阶段,每一阶段都给予适宜的温度条件,能够保证光合产物的充分积累和最低消耗,从而获得较高的产量。据试验,温室黄瓜应用该措施比常规温度管理(昼温28℃,夜温14℃)增产22%,节约燃料17%。
Greenhouse Cucumber four sections of the temperature management is based on the biological characteristics of cucumber and physiological activity within a day transfer rule developed a new cultivation management measures. It divides day and night into four stages, each stage is given appropriate temperature conditions, to ensure the full accumulation and minimum consumption of photosynthetic products, resulting in higher yields. According to the experiment, the cucumber application of greenhouse cucumber than the conventional temperature management (day temperature 28 ℃, night temperature 14 ℃) 22% increase, saving 17% of fuel.
