1. Pay attention to antifreeze insulation. Now that the residential housing conditions have improved, the closed balcony is very beneficial to the wintering of flower pots. If there is no enclosed balcony, potted flowers should be put in the room at night, and some special cold flowers such as tropical orchids, pineapples, poinsettia, and red The room temperature at the palm of your hand should not be less than 10°C. 2. Take care not to water too much water. The amount of water evaporation in winter is small. In addition, the stagnation of flower plants at low temperatures, especially the loss of vitality in the root system, excessive water, make the roots breathless, and can easily cause root diseases. Even rotten root died. 3, note that can not be more nitrogen fertilizer winter flower absorption capacity is not strong, excessive nitrogen fertilizer, will cause the basin soil electrical conductivity increases, damage the root system, at the same time, apply more nitrogen fertilizer, the leaves become tender, cold resistance, disease resistance The decline in capacity is not conducive to wintering. 4, pay attention to more sun exposure in winter light intensity is not high, flowers need to add more light, in order to facilitate photosynthesis, generate organic nutrients to increase the resistance of plants, for some winter flowering flowers, but also conducive to lush foliage, flowering Bigger and more beautiful. 5, pay attention to disease prevention and control pests are susceptible to winter diseases are fungal diseases, such as gray mold, root rot, disease, etc., the reason is nothing lower than the low temperature, high temperature, plant resistance decreased, so the key is to reduce the humidity, so that plants grow robust Enhance efforts in improving resistance, supplemented by chemical control. Insect pests are mainly against scale insects and aphids.
