Optimal seed germination conditions for cattail bio-platform remediation system

位于加拿大温尼伯省的Curry Industries Ltd.已经开发出一种香蒲生物平台收获系统的原型，该系统可以在水中系统的浮动框架上控制香蒲的生长，并提高营养含量，从而使这种潜在的生物修复介质在更深的水域中生长。通过在这些系统中促进香蒲的生长，营养物质从水柱中去除，从而减少了其他形成水华的藻类和蓝藻物种的营养物质的可用性。香蒲可以在生长季节结束时收获，生物质可以在土地上堆肥，用作花园或农田的肥料。拟议的ENGAGE拨款将在申请人和Curry Industries， Ltd之间建立合作研究伙伴关系，以确定最佳播种条件，以最大限度地提高香蒲生长。如果能够开发出一种可靠而简单的香蒲播种方法，生物平台将更容易扩展到大规模部署。在这项研究中，我们将确定发芽率和理想种子种植密度，以最大限度地提高香蒲在生物平台上的发芽和生长。

Curry Industries Ltd. in Winnipeg MB, has developed a prototype for a Cattail Bio-Platform HarvestingSystemTM that allows for the controlled growth of cattails on a floating frame in an aquatic system withelevated nutrients to allow for growth of this potential bioremediator in deeper waters. By encouraging thegrowth of cattails in these systems, nutrients are removed from the water column, thus reducing the availabilityof nutrients to other bloom-forming algal and cyanobacterial species. The cattails can then be harvested at theend of the growing season, and the biomass can be composted on land and used as fertilizer for gardens orcropland. The proposed ENGAGE grant will establish a collaborative research partnership between theapplicant and Curry Industries, Ltd to determine the optimal seeding conditions to maximize cattail growth.The Bio-Platforms will be more easily scalable to deploy in large volumes if a reliable and simple method ofcattail seeding can be developed. In this study, we will determine the germination rates and ideal seed plantingdensity to maximize cattail germination and growth in the Bio-platforms.
