连阴天气连阴天大棚内光照弱、温度低,这是影响大棚花卉正常生长的最关键因素。要想植株平稳度过连阴天,最重要的是尽量提高弱光环境下的光合效率,以增加养分制造量,同时尽可能降低呼吸消耗,减少养分流失。因此,冬春季连阴天大棚花卉管理必须围绕这一点来展开。 Even with cloudy weather cloudy sky light green house, the temperature is low, which is the most crucial factor affecting the normal growth of greenhouse flowers. The most important thing to do is to improve the photosynthetic efficiency under low light conditions so as to increase the amount of nutrients produced and reduce the respiratory consumption as much as possible while reducing the nutrient loss. Therefore, the spring and winter flowers and even cloudy management of the greenhouse must be started around this point.
