为了最大限度地利用海草作为基于自然的解决方案，需要进行大规模的恢复。需要新的方法和知识来解决生态瓶颈，提高其可靠性和有效性。尽管人们对利用种子恢复海草的兴趣越来越大，但对如何最好地种植海草的理解有限，大多数关于发芽和幼苗出苗的知识来自实验室研究。在这里，我们提出了一项新的实地研究结果，研究了不同种植处理下海草Zostera marina种子的出苗成功率。按照三种处理（沉积物类型、碎屑添加和营养添加）的析因设计将种子种植在麻袋中。通过在天然沉积物中添加营养物，本研究提供了一些海草芽出现和最大芽长加倍的证据。本研究提供的证据表明，即使在营养丰富的环境中，海草沉积物也可能需要额外的营养来促进幼苗的萌发和生长。它还强调了在浅海沿岸环境中种植海草种子的高度可变性。关键的是，这项研究提供了越来越多的证据，表明该方法中的细微之处可能对海草恢复产生重大影响，并且为了将恢复规模扩大到与基于自然的解决方案相关的水平，仍有许多未知因素需要考虑。
To maximize the opportunities of seagrass as a nature-based solution requires restoration to occur on a large scale. New methods and knowledge are required that can solve ecological bottlenecks, improving its reliability and effectiveness. Although there is increasing interest in the use of seeds for seagrass restoration there exists a limited understanding of how best to plant them with the most knowledge on germination and seedling emergence coming from laboratory studies. Here we present the results of a novel field study on the emergence success of seeds of the seagrass Zostera marina when subjected to varied planting treatments. Seeds were planted into hessian bags according to a factorial design of three treatments (sediment type, detritus addition, and nutrient addition). By adding nutrients to natural sediment, the present study provides some evidence of seagrass shoot emergence and maximum shoot length doubling. The present study provides evidence that even in heavily nutrient-rich environments, seagrass sediments may require additional nutrients to improve seedling emergence and growth. It also highlights the highly variable nature of planting seagrass seeds in shallow coastal environments. Critically this study provides increasing levels of evidence that small subtleties in the method can have large consequences for seagrass restoration and that for restoration to scale to levels that are relevant for nature-based solutions there remain many unknowns that require consideration.
