菜豆在节能日光温室内栽培,宜选用矮生品种,且一般作春提前和秋延后两茬栽培。菜豆是喜温植物,对温度的适应范围比较广,适应温度范围为15～29℃,因此它能适应节能日光温室的温度特点。菜豆属于短日照作物,但它在细苗期仍需要较长和较强的日照。节能日光温室内的光照虽比露地差,但春秋季栽培,一般都能满足它的要求。菜豆是自花授粉作物,在温室内一般都能开花结果,但过密、温度 Beans cultivated in energy-saving sunlight greenhouse, should use the dwarf varieties, and generally for spring ahead of schedule and the second crop cultivation. Bean is a thermophilic plant, the temperature to adapt to a wide range of adaptation temperature range of 15 ~ 29 ℃, so it can adapt to the energy-saving greenhouse temperature characteristics. The kidney bean is a short-day crop, but it still requires longer and stronger sunshine in the seedling stage. Although the light inside the energy-saving sunlight greenhouse is worse than the open field, cultivation in spring and autumn generally meets its requirements. Beans are self-pollinating crops that generally bloom in greenhouses but are over-dense and temperature-prone
