【摘要】 木质素存在于绝大多数陆生植物的木质部，估计占陆生植物生物量30%,对于维持地球生态系统的稳定性具有重要意义。在农林领域，多年来人们一直十分重视研究木质素相关产品的生产工艺，探讨了它对农作物和林木的地上部及地下部生长的影响，取得了许多有价值的研究成果，促进了农业和林业生产的发展。系统总结了木质素的性质，木质素对植物生长、土壤理化性质、土壤微生物的影响，以便为木质素在农林方面的研究与应用提供参考依据。更多还原

【Abstract】 Lignin existed in the xylem of most terrestrial plants, it was estimated to account for 30% of terrestrial plant biomass, it was significant for maintaining the stability of the Earth’s ecosystem. In the field of agriculture and forestry, people had been paying great attention to the research on the processing technology of lignin-related products, explored the effects of the above-ground and below-ground growth of crops and forest trees, obtained many valuable research results, and promoted the development of agriculture and forestry production for the past many years. In the paper, its properties, effects on plant growth, soil physical and chemical properties and soil microorganisms were summarized, in order to provide a reference for the research and application of lignin in agriculture and forestry.更多还原
