大棚蔬菜在春季需要加强管理,因温度不断提升,大棚夜温也不断上扬,管理不合理容易导致蔬菜发生激素中毒、徒长、高温障碍,从而导致蔬菜早衰、叶片黄化、落花、落果等现象,需要加强处理。一、光照和温度、湿度管理阳光是植株叶片光合作用的能量来源,光照条件的好坏直接影响植株的长势,春季大棚内空气湿度较大,温度高湿度大常会引发各种病害的发生,适时通风降温降湿是有效地控制病害发生的重要手段。正确的放风方法为,白天温度控制 Greenhouse vegetables need to be strengthened in the spring management, as the temperature continues to rise, the night temperature of the greenhouse also continue to rise, irrational management can easily lead to vegetable hormone poisoning, leggy, high temperature disorders, leading to premature aging vegetables, leaf yellowing, falling flowers, Need to be strengthened. First, the light and temperature, humidity management Sunshine is the energy source of photosynthesis of plant leaves, the light conditions directly affect the plant growth, the larger the spring air humidity in the greenhouse, high temperature and humidity will lead to a variety of diseases, the timely Ventilation, cooling and dehumidification are important means to effectively control diseases. The correct method of ventilation, daytime temperature control
