摘　　要：用造纸废液处理秸秆可显著提高秸秆的营养价值。用造纸废液加尿素复合处理秸秆可使秸秆的干物质消失率提高20个百分点,粗蛋白含量增加1.0～1.5倍,处理效果优于一般的尿素氨化处理。研究结果表明,取造纸废液用量20%～30%、尿素用量3%～5%,处理温度为25℃左右,并经过一定的处理时间,效果最佳。Treating straw with the waste liquor of paper mill can greatly improve the nutritive value of straw.The dual treated straw with the waste liquor and urea can have a 1.0～1.5 time increase of the crude protein and a 20% increase of dry matter disappearance compared with untreated straw.The treatment result is bet- ter than the urea treatment.The experimental results show that the favorable dosage of the waste liquor and urea should be 20%～30% and 3%～5%,respec- tively.The best result can be achieved under the condition of 25℃ and 7 days.
