Sweet potato is a common crop and vegetable, which can be planted and propagated, cultivated in soil or hydroponics. Hydroponics is simple, easy to survive and easy to manage. Before hydroponics, select a glass container with appropriate size, disinfect it with alcohol and dry it. After drying, fill the glass container with nutritious river water or well water.
Choose robust and undamaged sweet potatoes with buds, wash them, and put them in a glass container for hydroponics, with the buds facing up. Proper amount of 1 ~ 2 drops of nutrient solution can provide nutrition for sweet potato. Putting the glass container in a well-ventilated place indoors can stabilize the temperature at 5-35 degrees, which is beneficial to the germination of sweet potatoes.
During the maintenance period of hydroponic sweet potato, change the water regularly to keep the water clean. Generally, it takes 3-4 days to change water 1 time in spring and autumn, and 2-3 days to change water 1 time in high temperature period in summer. When changing water, it should be noted that the water temperature should be consistent with the indoor temperature. If the water temperature is too high, it will affect the normal growth of sweet potatoes.
Sweet potato will sprout and grow leaves in the later stage. In its growing period, appropriate amount of nitrogen fertilizer can be applied to sweet potato, which can promote the growth of branches and buds and make the leaves greener. After the sweet potato seedlings grow stably, they can be transplanted into loose, fertile soil with good ventilation and drainage performance, or they can be propagated by cutting.
