蔬菜(含幼苗)作物,对环境条件非常敏感,不良的恶劣的环境,会诱发许多类型的生理障碍。由于冬春季节气候变化异常,大棚蔬菜在长期阴冷、弱光、多湿的环境中,菜体营养消耗过多,叶绿素含量减少,抗逆力降低。如若栽培管理不善,会形成僵苗或引起落花落果。久阴后突然曝晴,又会发生植株萎蔫,低温多湿环境,会引起沤根。冬春大棚蔬菜,根据天气情况进行栽培管理,不仅能避免生理 Vegetables (including seedlings) crops, are very sensitive to environmental conditions, poor adverse conditions, will induce many types of physical disorders. Due to the abnormal climate changes in winter and spring, greenhouse vegetables in the long-term cold, light, wet environment, too much nutrition consumption of vegetables, chlorophyll content decreased, reducing the resilience. If cultivation and management is not good, it will form stiff seedlings or cause plum blossom. Long Yin suddenly exposed after the clear, wilting plants will occur again, low temperature and humidity environment, can cause purplish root. Spring and winter greenhouse vegetables, cultivation and management according to the weather conditions, not only to avoid the physiology
