在世界许多地方，农田授粉媒介在 20 世纪下半叶显着减少，主要是由于土地利用变化和农业集约化。我们研究了不同典型作物轮作和农业环境计划 (AES) 对爱沙尼亚熊蜂多样性的影响。我们比较了四种作物轮作类型（谷物轮作[一年到下一年没有变化]、谷物到大量开花作物[以下简称 MFC]、MFC 轮作和 MFC 到谷物田）之间的物种丰度，其中所有计数均在第二年进行，并且在三种农业类型（传统农业、有机农业和环境友好管理）中进行。我们连续五年沿 401 个田地边缘调查了熊蜂和花卉覆盖情况，记录了 20 个物种和超过6,000 人。谷物轮作田地边缘的长舌和受威胁的熊蜂物种数量高于其他三种轮作类型。此外，谷物轮转田地边缘比 MFC 轮转和 MFC 到谷物或谷物到 MFC 田地边缘具有更高的中等群体物种、通才和森林灌丛物种丰度。两种 AES 类型田间边缘的熊蜂物种丰富度均高于传统农业。然而，总的来说，熊蜂存在的最强驱动因素是花朵覆盖。谷物翻滚田地边缘的熊蜂丰度较高可能是由于那里的集中效应和/或 MFC 田地的稀释效应。两种 AES 方案都支持增加田地边缘的花朵覆盖率，从而增加熊蜂的多样性，表明 AES 对野生授粉媒介有积极的影响。合成和应用。轮作和农业环境计划通过花卉资源的可用性来决定熊蜂的丰富度和丰度，但轮作对熊蜂的限制因熊蜂的性状而异。因此，未来的农业环境政策应考虑这些管理方案。轮作可能是增加农业景观生物多样性的简单而有效的解决方案。
In many parts of the world, farmland pollinators decreased significantly during the last half of the 20th century mainly due to land‐use changes and agricultural intensification.We studied the effect of different typical crop rotations and agri‐environment schemes (AES) on bumblebee diversity in Estonia. We compared species abundances between four crop rotation types (cereal rollover [no change from 1 year to the next], cereal to mass‐flowering crops [hereafter MFC], MFC rollover and MFC to cereal fields) where all counts were conducted in the second year and in three farming types (conventional farming, organic farming and environmentally friendly management).We surveyed bumblebees and flower cover along 401 field margins in five consecutive years and recorded 20 species and more than 6,000 individuals. Abundances of long‐tongued and threatened bumblebee species were higher at the field margins of cereal rollover fields than for the other three crop rotation types. In addition, cereal rollover field margins had higher abundances of medium colony species, generalists and forest‐scrub species than MFC rollover and MFC to cereal or cereal to MFC field margins. Bumblebee species richness was higher at the field margins of both AES types than those of conventional farming. However, in general, the strongest driver of bumblebee presence was flower cover.Higher bumblebee abundances in cereal rollover field margins were probably owing to a concentration effect there and/or a dilution effect into MFC fields. Both AES schemes supported increasing flower cover in field margins and thereby diversity of bumblebees, indicating positive AES impacts upon wild pollinators.Synthesis and applications. Crop rotation and agri‐environment schemes determine bumblebee richness and abundance via the availability of flower resources, but crop rotation constrains bumblebees differently based on their traits. Therefore, future agri‐environmental policy should account for these management options. Crop rotation could be a simple, but efficient solution to increase the biodiversity of agricultural landscapes.
