The invention discloses a biomass particle and heat pump combined heating method for a bulk curing barn. According to the biomass particle and heat pump combined heating method for the bulk curing barn, a biomass particle burner and an air source heat pump are additionally arranged on an ordinary coal-fired curing barn, and the air source heat pump is used for heating in the baking stage at the temperature below 42 DEG C; biomass particles burn for heating in the baking stage at the temperature over 42 DEG C; and the heat pump and biomass particles are combined for heating in the moisture discharging stage. Compared with the ordinary coal-fired curing barn, labor for baking can be obviously reduced, and energy-saving and emission-reduction advantages are remarkable; compared with a heat pump heating type bulk curing barn, the working efficiency of the heat pump can be improved, the electric load required by the bulk curing barn is reduced, and an extra high-power standby power supply is not needed except the heat pump; and compared with a biomass particle heating type bulk curing barn, failures, caused by a large quantity of tar generated when biomass particles burn at a low temperature, of the burner in use are avoided, and complete combustion of biomass particles is promoted.
