Development of methods for multi-seed pellets using native shrubs and forbs

采矿后复垦的监管是复杂的，要求资源开采行业建立一个功能齐全的草本、灌木和乔木植物群落。大多数情况下，设想的植物群落是通过苗木苗木实现的。重建植物群落的一种经济有效的替代方法是直播。在开垦地成功利用种子受制于播种情况极差。种子与土壤接触不良、捕食造成种子损失、种子休眠是限制出苗和建植成功的主要因素。种衣剂是将同一种或不同种的单粒或多粒种子包被到含有有效成分的单一分散单元中的一种做法。将这项技术应用于本地灌木和杂草，可以为复垦企业在复垦场地应用直播播种时遇到的挑战提供解决方案。该项目旨在帮助一家小型企业开发灌木和叉树多种子颗粒的方法，并对其发芽和幼苗生长进行测试。该项目将评估添加三种不同的填充材料和有机粘合剂，以覆盖来自两个灌木和两个杂草的两个种子物种；然后在实验室和温室进行发芽测试。该项目的成果将使苗圃和复垦企业掌握有效的种子改良方法，但由于主要跨国种子公司的“商业保密”，它们无法获得这些方法。中小型企业也缺乏进行科学实验和开发种衣剂配方的能力。预计研究结果将提高商业播种过程的效率，提高种子出苗率和存活率，降低填海成本，并允许修复从业者在填海地点建立植物物种多样性。

Post-mining reclamation regulation is complex and requires the resource extraction industry to establish a fully functioning plant community of herbaceous, shrubs, and trees. Most often, the envisioned plant communities are achieved using nursery stock seedlings. A cost-effective alternative method to re-establish plantcommunities is by direct seeding. The successful use of seeds in reclamation sites is constrained by a very poor establishment of sown seeds. Poor seed-to-soil contact, loss of seed due to predation, and seed dormancy are among the main factors limiting seedling emergence and plants establishment success. Seed coating is thepractice of covering single seed or multiple seeds of the same or different species into a single dispersal unitwith active ingredients. The application of this technology to native shrubs and forbs could provide a solution to challenges that reclamation enterprises encounter while applying direct broadcast seeding on reclamationsites. This project aims at assisting a small enterprise in developing methods for multi-seed pellets of shrub andforb and testing their germination and seedling growth. The project will assess the addition of three different filler materials with an organic binder to coat two seed species from two shrubs and two forbs; followed bygermination testing in the lab and greenhouse. The project outcomes will equip nurseries and reclamationenterprises with efficient seed enhancement methodology, which they do not have access to due to'commercial-in-confidence' by the major multinational seed companies. Small- to medium-sized enterprises(SMEs) also lack the capability to conduct scientific experiments and develop their seed coating recipes. It is anticipated that the findings of the study will increase efficiency in the commercial seeding process, improve seed emergence and survival rate, reduce the cost of reclamation, and allow restoration practitioners toestablish plant species diversity in reclamation sites.
