Disclosed are a cultivation carrier and a cultivation system. The cultivation carrier comprises: a floating carrier body (102), the carrier body (102) being provided with at least one cultivation hole (104), and further comprises: at least one ventilation structure (108) in communication with the cultivation hole (104), wherein the ventilation structure (108) can enable the external air to enter the cultivation hole (104), the cultivation hole (104) comprises an upper part and a lower part, a plant (110) enters from an opening of the upper part and is supported at the upper part, and at least a part of a root system (110A) of the plant (110) is located at the lower part. The cultivation carrier and the cultivation system can enable the external air to enter the cultivation hole (104) during the process of cultivating the plant (110) so as to enable the root system (110A) of the plant (110) to be in contact with oxygen in the air, thus reducing the decomposition of the root system (110A) during the process of
