摘　　要：利用单螺杆挤压机对农作物秸秆进行颗粒饲料的加工试验。通过单因素试验和通用旋转组合试验,找出各影响因素及其间的交互作用对性能指标的影响规律,建立数学模型,并对试验结果进行分析;对秸秆进行碱化处理再挤压成形,经分析测试,该方法可明显降低粗纤维含量,从而有利于动物消化率和采食率的提高。Experiment of processing pellet for crop straw by single-screw shaping extruder was carried out. The mathematical models describing functional parameters were established by single factor experiments and general rotary regression design for second power. Test results were analyzed; Smashed bean straw was extruded after dealing with sodium hydroxide. With the help of analysis and determination, it was found that this method could reduce the content of coarse fiber and improve intake ratio and digestive ratio.
