The invention relates to a low-energy-consumption precise baking method and system for improving tobacco leaf baking quality, and belongs to the field of tobacco leaf modulation. The method comprisesthe steps that on the basis of a conventional bulk curing barn, an air dehumidification device, an air heating device and a control system are arranged, and return air of the bulk curing barn is dehumidified and heated through the air dehumidification device and the air heating device; the bulk curing barn is divided into a plurality of areas, and each area is provided with a variable air volume air mixing valve and an air supply outlet; the dehumidified and heated air is respectively fed into inlets of the variable air volume air mixing valves in all the areas through air pipes; the control subsystem adjusts the mixing proportion and the air volume of each variable-air-volume air mixing valve in real time, so that the tobacco leaf baking quality is improved, and the energy consumption isreduced. The tobacco leaf
