Rescue measures of flowers after waterlogging

Long-term overcast rain or irrigation watering too much, low-lying waterlogging or flowerpot bottom hole is blocked, resulting in waterlogging hypoxia, so that flowers are waterlogged, roots become brown and rotten, leaves turn yellow, branches and leaves wilt, resulting in fallen leaves, flowers and withered branches, and the whole plant dies over a long time. In order to reduce the loss of waterlogging, rescue measures should be taken quickly after flowers are waterlogged.

1. Drainage for ground-planted flowers to open ditches and drainage, for potted flowers to dredge the bottom hole of the flowerpot, drain the stagnant water in the pot, move the flowerpot to a place where rain is ventilated and dry, and reduce the humidity of the potted soil. After waterlogging, the roots of flowers were damaged to a certain extent, and the absorption function decreased. In order to maintain the relative balance between root water absorption and foliar transpiration, foliar spray or anti-transpiration agent was sprayed with clear water while strengthening soil drainage, so as to reduce plant water loss and promote normal growth as soon as possible.

2. The consolidation of soil after stagnant water is the cause of anoxic rotting roots. After being flooded, the flowers should be ploughed and loosened in time to enhance the air permeability and meet the oxygen needs of the root system.

3. Change the soil and plane the wet soil on the surface of the root and replace it with dry soil. For potted flowers, plant ash or dry soil is applied on the potted surface to reduce the water content of the roots and promote the recovery of metabolic function. For the potted flowers with stagnant water for a long time, knock out the plant together with the soil ball from the basin, put it in a cool and ventilated place, make it evaporate water, and return to the basin for maintenance when it returns to normal water content three or four days later.

4. Keep the flowerpot in a cool and ventilated place to prevent sudden sun exposure. Due to the flowers after waterlogging, the root absorption function is obviously weakened, such as sudden sun exposure, aggravating the water loss of branch and leaf transpiration, resulting in wilting.

5. After the fertilizer-controlled flowers were waterlogged, the root system was damaged in varying degrees, and the absorption function decreased significantly, so there was no need to apply fertilizer, otherwise it would accelerate the death of the plant. When the root system returns to normal absorption and metabolism function, then fertilize, light fertilizer is applied frequently, and the concentration should not be too high.
