生态恢复领域草种丸粒化研究进展

Review of grass seed pelletizing in ecological restoration

生态环境治理,是我国提出的旨在保护和建设好生态环境,实现可持续发展的战略决策。退化草地修复和矿山生态恢复是我国生态环境治理重要的任务之一。而当前草地退化严重区的治理难点主要集中在种子萌发和幼苗生长两个阶段。种子丸粒化作为一种种子管理技术,在促进种子萌发、增强出苗率和提高播种能力等方面具有重要作用。通过丸粒化机将种子与丸粒化配方粉剂相结合,制成不同倍数的丸粒化种子,以改善土壤与种子的接触面和生存环境,为生态恢复提供充分的基础保障。前期通过查阅大量有关种子丸粒化相关文献和专利等资料,本研究综述了可被使用在退化高寒草地治理、高寒矿区修复,以及退牧还草等生态恢复领域的种子丸粒化材料,包括填料、黏合剂和活性成分等。以期为我国生态修复工程提供科学理论依据,进而为种子和草种业的高质量发展提供一种新路径。

Ecological environmental management is a strategic direction proposed by China in order to protect and build a healthy ecological environment and achieve sustainable development.Ecological restoration of degraded grassland and historical mine sites is one of the important tasks of ecological environment management in China.At present,the management difficulties in the degraded areas are mainly related to seed germination and seedling growth.Seed pelletizing as a seed management technology plays an important role in promoting seed germination,enhancing seedling emergence and improving seeding establishment capacity.By combining seeds with formulated powder applied through pelletizing machines,different types of pelletized seeds were developed that improved the contact surface between soil and seeds and improved the seed survival environment,so providing improvement in seed establishment to ensure successful ecological restoration outcomes.Based on a large amount of literature and patents related to seed pelletizing,this study reviews seed pelletizing materials,including fillers,binders and active ingredients,that can be used in ecological restoration fields such as alpine grassland degradation management,alpine mine restoration and pastureland rehabilitation.This work provides technical data for the development of high quality seeds and a successful grass seed industry in China.
