In the winter, due to the low temperature and low light, many flowers need to enter the indoor nursery. Most flowers are in a dormant and semi-dormant state. Managing flowers at this time will cause death and death of flowers due to improper technology. The causes of the death of flowers and their prevention and control measures are as follows: First, the reason 1. Watering amount. During the winter season, the flowers cannot be watered blindly due to the fact that the flowers are not long and the temperature is low, the evaporation is small, and the transpiration is low. Excessive watering will cause the leaves to yellow, and water shortage will make the leaves wilting and change. Brown. 2. The temperature is too low. A notable feature of winter is that the temperature is low, and flower growers cannot timely put the flowers in a warm place according to this feature. Over time, the flowers are wilting due to insufficient temperature. 3. The light is weak. Although the lack of indoor illumination will not cause the death of flowers, it will show poor growth and development, pale leaf color, small leaves, and failure to flower. 4. Frost effects. In winter, because the indoor and outdoor temperatures are very different, if the indoor flowerpots are placed improperly and placed on the door seams, window seams, etc., they will be blown by cool winds, withering, severe and even death. Second, prevention measures 1. Water should be appropriate. Most flowers in winter go to sleep and stop growing. Watering should be controlled but not equal to not watering. Because the roots of flowers are still undergoing slow breathing activities, they also need a certain amount of water supply, but only a small amount. With less evaporation and less evapotranspiration, it is possible to pour water once in a relatively long period of time. The principle is to quit, not to pour, to pour, and to water at noon in winter. Water temperature and pot temperature do not differ too much. Rainwater, well water, river water, and tap water can all be used. If the water temperature and temperature are significantly different, water can be stored in water tanks, buckets, and other containers for a period of time. It is generally preferable to water once every 5 to 7 days. 2. Avoid nighttime low temperatures. The environment in which the potted flowers are located has a higher daytime temperature, and the greater its damage is caused by the low temperature at night. At night, move the flowers to the inside or cover it with a plastic film. 3. Adjust the lighting timely. Flowers placed in corridors, corners of rooms, etc., where there is insufficient light, should be changed regularly and often moved to a sunny place. 4. Prevent frost. The flowers placed on the windowsill are most vulnerable to freezing. Therefore, do not put pots on the window sill at night when the temperature is low, and put the curtains down at the same time. If the weather forecast has cold or frost and the room cannot be warmed, remove the flower pot from the window sill. 5. Change indoor dry hot air. In winter due to indoor heating or other reasons, the indoor air humidity is generally low. Such environmental conditions are extremely detrimental to the growth of many indoor flowers, and some delicate flowers may even die in such an environment. Always spray water on flowers to increase its humidity and ensure the normal growth of flowers.
