Treatment of rotten Root of hydroponic Flowers

Methods: with the continuous increase of air temperature, the water temperature will also rise, the propagation of microorganisms will be accelerated, the dissolved oxygen will decrease, and the water quality will deteriorate. Improper addition of nutrient solution and too high dissolved concentration may lead to root rot of hydroponic flowers, especially Zhu banana of Liliaceae, horsetail iron (fine leaf millennium wood) and five-colored millennium wood.

Flowers with rotten roots can regain their growth by using the following methods:

The flowers washed by ④ are put into the original utensils and cultivated in clean water (the utensils should be washed).

⑤ every two days to change the water, only change the water without nutrient solution. The water quality is clear, which can reduce the number of water changes. New roots can sprout after 10-15 days.

The newly sprouted roots of ⑥ were still cultivated in clear water, when the temperature was stable at 18-25 ℃, and cultivated in nutrient solution.
