摘　　要：分别采用正交试验和单因素试验方法研究漆酶活化法制造竹材刨花板的酶处理工艺和热压工艺,结果表明:竹材刨花漆酶处理优化工艺参数为酶用量30U/g、反应体系pH值4、处理时间2h、处理温度60℃;当板材密度为0.70g.cm-3、厚度为10mm时,热压优化工艺参数为热压压力4.0MPa、热压温度200℃、板坯芯层温度140℃、热压时间17.5min。The lacease treatment conditions and the hot-pressing technology parameters were studied systematically by orthogonal test and single factor experiments. The optimal laccase treatment conditions were obtained as enzyme dosage 30 U/g, pH 4, incubation time 2 hours, incubation temperature 60 degrees C. The best hot-pressing parameters for the bamboo parti-cleboard with density of 0.70 g·cm^-3 and panel thickness of 10 mm were obtained as hot-pressing pressure 4.0 MPa, hotpressing temperature 200 degrees C, mat core temperature 140 degrees C, and hot-pressing time 17.5 minutes.
