A method of cultivating plant in transparent sealed container and base used therefor, wherein the base is mainly obtained by solidifying a mixture formed by adding gellan gum to transparent nutritional liquid; the gellan gum being added to the nutritional liquid is in an amount of 2-10 g/L; the base has a PH value of 3.5-10.0. The use of gellan gum as the sole transparent solidifying agent ensures the gellan gum, the base of the present invention is capable of adhering securely in the transparent sealed container. As shown by experiments, the base of the present invention will not slide or disperse in the transparent sealed container under normal shaking state, and can remain adhered to the transparent sealed container for 3-10 minutes when the transparent sealed container is turned upside down.
