Abstract��
Environmental organic fertilizer which can fix sand and maintain soil was obtained by environmental black liquor produced in papermaking process after evaporation,improved treatment.The black liquor contained large amount of lignin with great cohesive property because soda was replaced by magnesium ammonium in the papermaking process.The experiments in room and out room were carried out in China Academic Sinica Desert Laboratory.The results indicated that:the effect of fixing sand is obvious,the anti-wind erosion performance is very good.Because the organic content is nearly 40%,it can give nutrient for desert and sand,and favor the desert plant to grow to obtain long-term fixing sand.To widely apply this complete set of innovation technology can not only eradicate the pollution of waste liquid of papermaking but also solve the technical difficult problem on fixing sand and controlling desert.It has notable benefit in environment,society and economy.
