造纸废液木质素用于边坡植被建植的探索

摘要

The mechanism, methods, functions, characteristics and application effects of the chemical modification of lignin in paper making waste liquor used as base planting material additive to the vegetation construction in difficult slope-site were explored and practiced. The results showed that the base planting material additive had a lot of functions and good performance. It can effectively improve planting base material's ability of maintenance of water and fertilizer, supplying of fertilizer and stress resistance of plants, especially suitable for the site conditions especially bad for high and steep slope vegetation construction. It provides new ideas and supporting technical to solving industry common problems, such as base planting material easy to slide, easy degradation of vegetation, and so on. It also provides a new approach for resource utilization of papermaking wastewater.%对造纸废液木质素化学改性、谱学分析以及作为植生基材添加剂用于边坡困难立地植被建植的机理、方法、功能、特点、应用效果等进行了探索和实践.结果表明,造纸废液木质素化学改性后,用作植生基材添加剂功效多,性能好,能有效提高植生基材保水、保肥、供肥性能及植物的抗逆能力,尤其适合水热条件特别恶劣,施工养护极为不便的高陡岩石边坡的植被建植,为解决植生基材易滑落、植被易退化等行业共性难题提供了新的思路和支撑技术,亦为造纸废液的资源化利用提供了新途径.
