夏季,棚室温度迅速升高,给蔬菜生产带来很多问题,而高夜温是引发诸多问题的关键。夜间基本没有光照,有机营养处在单纯消耗的状态,若温度过高,呼吸作用一直维持在高强度,会导致白天制造的有机营养大量消耗,有机营养不足,使得植株细弱、落花落果严重。因此菜农朋友一定要注意夜温的控制。遮阳与浇水结合白天,为了将棚内温度降下来,菜农们应该都尝试过多种方法,如覆盖遮阳网、喷降温剂、泼泥浆等,但有时难以达到预期目的,反而使植株
In summer, the temperature of greenhouse rapidly rises, which brings many problems to vegetable production. High night temperature is the key to many problems. There is no light at night, and the organic nutrition is in a state of pure consumption. If the temperature is too high, the respiration will be maintained at a high level for a long time, leading to a large amount of organic nutrition consumed in the daytime and insufficient organic nutrition. Therefore, farmers and farmers must pay attention to the control of night temperature. Shade and water combined with the daytime, in order to lower the shed temperature, vegetable farmers who have tried various methods, such as shade net coverage, cooling agent, splashing mud, but sometimes difficult to achieve the desired purpose, but the plant
