番茄是喜温作物,长时间生存在5℃以下的低温环境里,植株会因冻害导致叶片失绿且呈白化状,进而导致植株死亡。番茄冻害的症状与番茄缺镁症状非常容易混淆。缺镁症是因镁素的缺乏造成叶肉褪绿黄化,虽然因天气低温、氮磷肥过量,影响镁肥的吸收,易产生缺镁症,但分析季节气候,在气温较低的深冬如果出现叶片褪绿,首先应考虑是低温冻害。从季节气候入手,通过科
Tomato is a thermophilic crop, long-term survival in the low temperature below 5 ℃ environment, the plants will be due to frost damage leaves green and whitish, leading to plant death. The symptoms of tomato frost damage and tomato magnesium deficiency symptoms are very easy to be confused. Magnesium deficiency is caused by the lack of magnesium leaves mesophyll chlorosis, although due to the weather is cold, excessive nitrogen and phosphorus, affecting the absorption of magnesium fertilizer, magnesium deficiency disease is easy to produce, but the analysis of seasonal climate in the winter, if the temperature is low if Leaves appear chlorotic, should first be considered low-temperature frost damage. From the seasonal climate, through the Section
