The invention relates to a distributed intelligent flower cultivation management system based on NB-IOT. The system comprises distributed monitoring ends, a control end and a cloud server, wherein each monitoring module in distributed monitoring ends uploads collected environment monitoring data of flower planting to the cloud server; the cloud server sends a control command to the control end according to the environment monitoring data uploaded by each monitoring module; the control end receives a control command sent by the cloud server, and controls corresponding facilities of a flower planting area and adjust a flower planting environment parameter according to the control command. The system provided by the invention utilizes the characteristic that the NB-IOT technology has dense and massive connections to creatively achieve the intelligent cultivation of lots of different kinds of flowers; the flowers can be increased by only needing to increase the NB-IOT monitoring modules ofthe flowers without changing the control end, the cloud server and the intelligent terminal, so that the cost is greatly saved, and meanwhile the user management is facilitated.
