In order to develop the optimized fire retarding treatment process,the authors used nitrogenphosphorus-boron fire retardant to treat poplar with different impregnation methods. Fire resistances of samples were evaluated through the limiting oxygen index ( LOI) ,drug loading,impregnation depth,heat release rate,and total heat release. Results showed that the optimized process was microwave heating samples for 2 minutes,impregnating the samples under ultrasonic waves for 30 minutes under a temperature of 40 ℃ . Under the same treatment,fire resistance of sapwood samples was slightly better than that of heartwood samples.
