覆盖物胶水是一种由丙烯酸或聚氨酯聚合物制成的无毒水性粘合剂，被用来防止鸟类在花园中翻动覆盖物[1]。虽然这类产品允许水和空气渗透到土壤中，但使用它们可能会带来生态代价[1]。
鸟类在花园中翻动覆盖物的行为实际上是有益的[1]。这一活动有助于土壤通气，增加有机物含量，并为土壤微生物和昆虫创造良好条件[1]。相比之下，覆盖物胶水虽然具有紫外线稳定性，但持久存在于环境中，降解时可能将塑料颗粒释放到水道和排水管中[1]。此外，有关该产品的同行评审研究很少，但专家对其可能通过减缓覆盖物分解而间接影响蚯蚓和其他土壤生物的方式表示担忧[1]。
在大多数情况下，园艺专家建议应该接受花园中的自然混乱，而不是依赖覆盖物胶水等产品[1]。不过，在某些特殊情况下，例如陡峭斜坡或老年人和行动不便人士管理的花园中，初次应用这类产品可能是有益的[1]。
Landscape glue—a non-toxic, water-based adhesive made from acrylic or polyurethane polymers—has emerged as a tool to prevent birds from disturbing garden mulch [1]. While the product allows water and air to penetrate the soil, it may restrict the foraging activities that birds naturally perform in gardens [1].
This restriction carries ecological consequences. Bird foraging contributes significantly to soil aeration, increases organic matter content, and benefits soil microorganisms and insects [1]. Landscape glue is designed with UV stability to persist long-term, but when it degrades, it may release plastic particles into waterways and drainage systems [1]. Additionally, peer-reviewed research on mulch glue remains scarce, though concerns exist that by slowing mulch decomposition, the product could indirectly harm earthworms and other soil organisms [1].
For most gardeners, accepting some natural messiness in the landscape may be preferable to relying on such products [1]. However, the initial application of mulch glue may offer practical benefits in specific circumstances, such as on slopes or for elderly and mobility-limited gardeners [1].
