传粉媒介减少的原因之一是构成其营养需求的花卉资源的可用性减少。特别是，农业做法的集约化导致了花卉资源的损失。多年来，作为共同农业政策和保护生物多样性努力的一部分，欧洲一直在推广几项农业环境计划和广泛的耕作方法。为了评估广泛的农业实践，如绿篱，有机作物和广泛的草地的相对贡献，我们比较了比利时的农业景观对。记录了每个生境和每个月的昆虫传粉植物物种密度、主要访花昆虫的丰度和多样性。4月，灌木篱和林缘构成了主要的花蜜资源。5月份，大部分花蜜资源由草原和大量开花作物产生。6月，大面积草地和有机作物对花蜜资源的贡献与农业要素的密集相反。因此，应鼓励广泛和多样化的农业做法，在景观尺度上提供波动较小的花蜜资源。农业实践的强化导致花卉资源的丧失，并导致传粉媒介的减少。欧洲鼓励广泛的农业做法，这有助于保护生物多样性。我们比较了三个农业景观没有广泛的耕作方式与三个相邻的景观有机作物和广泛管理的草地在比利时。花蜜资源的可用性和植物传粉者的相互作用进行了监测，从4月至6月。每种植物的花密度和植物-传粉者的相互作用记录在不同的景观元素。4月，主要的花蜜资源是由线性元素，如树篱和森林边缘。在密集的草地和大量开花作物的推动下，花蜜产量在5月达到顶峰。广泛的草地和有机作物的出现显着缓解花蜜资源的差距观察到6月。我们的研究结果强调了保持景观异质性的重要性，为连续的花卉资源，并突出了广泛的草地和有机作物在6月的具体作用。
One of the causes of pollinator decline is the decreased availability of flower resources, that constitute their nutritional requirements. In particular, the intensification of agricultural practices has led to a loss of flower resources. For many years, as part of the Common Agricultural Policy and the efforts to preserve biodiversity, several Agri-Environmental Schemes (AESs) and extensive farming practices have been promoted in Europe. To assess the relative contribution of extensive farming practices such as hedgerows, organic crops and extensive grasslands, we compared pairs of agricultural landscapes in Belgium. We recorded the densities of the insect-pollinated plant species per biotope and per month, the abundance and diversity of the main visiting insects. In April, hedgerows and forest edges constituted the main nectar resources. In May, most of the nectar resources were produced by grasslands and mass-flowering crops. In June, extensive grasslands and organic crops contributed to nectar resources, contrarily to intensive agricultural elements. Extensive and diverse agricultural practices should therefore be encouraged to provide less fluctuating nectar resources on a landscape scale. Intensification of agricultural practices leads to a loss of floral resources and drives pollinator decline. Extensive agricultural practices are encouraged in Europe and contribute to the preservation of biodiversity. We compared three agricultural landscapes without extensive farming practices with three adjacent landscapes containing organic crops and extensively managed grasslands in Belgium. Nectar resource availability and plant–pollinator interactions were monitored from April to June. Flower density per plant species and plant–pollinator interactions were recorded in different landscape elements. In April, the main nectar resources were provided by linear elements such as hedgerows and forest edges. Nectar production peaked in May, driven by intensive grasslands and mass-flowering crops. Occurrence of extensive grasslands and organic crops significantly alleviated the nectar resource gap observed in June. Our results underscore the importance of maintaining landscape heterogeneity for continuous flower resources and highlight the specific role of extensive grasslands and organic crops in June.
