Second, hydroponic green radish can refer to the following points:
1. First, we must choose the branches and stems of the green radish. Healthy and robust branches and leaves with aerial roots are good hydroponic objects, so that the branches and leaves with aerial roots can adapt to the hydroponic environment quickly after being cut and put into clean water, and water roots can grow in about ten days. Note that the branches and leaves put into the water cannot have leaves, otherwise the leaves will easily affect the water quality.
2. Pay attention to changing water a few days before hydroponics, at the same room temperature every two or three days, and once a week after the produced water takes root. When new leaves grow, you can replenish nutrient solution every ten days or so, or spray some diluted nutrient solution on the leaves, which will make the leaves green and shiny.
3. The roots of hydroponic radishes should be cleaned and repaired frequently. If the root system is too long, it should be cut short in time to avoid nutrient loss. If the root system is rotten and sticky, it should be cleaned in time, cut off the rotten root system, soaked in potassium permanganate solution for disinfection and then restored to maintenance. Water should be changed every two or three days a few days before the restoration of maintenance, and every ten days after the growth is fully restored, just like the initial hydroponics.
4. hydroponic radish needs enough scattered light to make its leaves stretch and turn green. Usually, it is best to place it where there is enough scattered light. If the environment is too dark, you can move to a place with enough scattered light for a few hours every ten days or so, and you can also keep the luster of the leaves.
5, the green radish itself likes a warm and humid environment. In the dry season, it is necessary to spray water on the leaves frequently to increase the humidity of the environment, which can also play a role in cleaning the leaves. Keep away from heating in winter and pay attention to prevent frostbite. Hydroponics leaves are delicate and sensitive to temperature changes, so attention should be paid to keeping the room temperature as normal as possible, and there should be no big temperature difference.
6, hydroponic green radish also needs to be trimmed frequently, cut off long and messy branches, and maintain a dense and orderly appearance.
