A method of cultivating plants in a transparent sealed container, comprising the following steps: S1: selecting a transparent container with an opening, wherein the opening is engaged with a sealed plug; S2: preparing a base, by: S21: adding gellan gum to a transparent nutritional liquid to form the base for cultivating plants; wherein an electric conductivity corresponding to a soluble salt content in the base is lower than 0.5 mS/cm; wherein the gellan gum being added to the transparent nutritional liquid is in an amount of 8-10 g/L; wherein the base is obtained in form of a transparent liquid; and wherein a pH value of the base is adjusted to 3.5 - 10.0; S22: filling the base in liquid form as obtained in Step S21 into the transparent container and sealing the opening of the transparent container with the sealed plug; S23: sterilizing the transparent container obtained in Step S22 at a temperature of 122±2°C and a pressure of 1.06±0.02 Kg/cm 2 for 15-40 minutes, then cooling down to room temperature until the base in liquid form in the transparent container solidifies; S24: performing an adhesive treatment on the sterilized transparent container obtained in Step S23 at 20-25°C, RH30-50%, 5-20 μmol/m 2 /s; wherein after 5-14 days the base and the transparent container adhere to each other and do not slide against each other; and wherein during the entire adhesive treatment the transparent container is positioned at a vertical position; S3: in a sterile environment, removing the sealed plug, and cultivating a live sterile plantlet or sterile seed to the solidified base via the opening of the transparent container; wherein the live sterile plantlet or sterile seed is cultivated according to a plant growth direction to ensure harmonization among the plant, the base and the container; finally sealing the sealed plug to ensure that the live sterile plantlet or sterile seed is cultivated in a sterile environment; S4: positioning the transparent sealed container with the cultivated live sterile plantlet or sterile seed under a temperature of 20-27°C, a humidity of RH30-70%, and a light intensity of 10-200 μmol/m 2 /s for 2-6 weeks; to grow new leaves and new root system, wherein Angiospermae and the base match with each other.
