Review of grass seed pelletizing in ecological restoration

doi:10.11686/cyxb2022152

Abstract

Abstract:

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.

Key words: seed pelletizing, ecological restoration, degraded grassland restoration, revegetation
