The invention relates to the technical field of nursery stock drip irrigation, in particular to a nursery stock drip irrigation device based on the Internet of Things. The nursery stock drip irrigation device comprises a drip irrigation mechanism, supporting mechanisms, adjusting mechanisms, water shutoff mechanisms and a fertilizer application mechanism. The two sets of water shutoff mechanisms are installed on the surface of the drip irrigation mechanism, when one position of the drip irrigation mechanism needs to be shut off, the set of water shutoff mechanism is made to slide, then one endof the drip irrigation mechanism is shut off, the situation that drip irrigation is carried out on places without nursery stocks is avoided, water resources are saved, meanwhile, the drip irrigationmechanism can be protected when not used, and impurities are prevented from entering and blocking the drip irrigation mechanism. The adjusting mechanisms are arranged between the water shutoff mechanisms and the supporting mechanisms, on one hand, the water shutoff mechanisms and the supporting mechanisms are connected, on the other hand, sliding ways are provided for the water shutoff mechanisms,adjustment of the water shutoff mechanisms is facilitated, and meanwhile the drip irrigation mechanism is supported; and the fertilizer application mechanism is mounted on the surface of the drip irrigation mechanism, pesticides and fertilizer are dripped on nursery stocks, and the nursery stocks are subjected to fertilizer application and pest prevention.
