通过确定最能吸引授粉者的红三叶草(Trifolium pratense)栽培品种,改善花粉和花蜜供应
红三叶(Trifolium pratense)是农业中一种重要的豆科植物,可用作饲料和提高土壤肥力。在开花期间,红三叶草的花也是授粉者宝贵的花粉和花蜜来源。农民可以从数百种市售的红三叶草栽培品种中选择种植,但不同栽培品种对传粉昆虫的价值目前尚未得到评估,也未作为农民的推荐标准。在此,我们比较了 2022 年和 2023 年在英国青贮饲料生产的典型管理下种植的 20 个红三叶草品种(12 个栽培品种和 8 个育种品系)上的传粉昆虫数量。我们还测量了其他可能对授粉者友好的性状(花序密度、每花序小花数、小花长度和花蜜糖产量),以帮助确定哪些性状适合纳入红三叶草育种计划。每个小区吸引的传粉昆虫数量相差很大,达到 50 倍之多,而且所有其他考察性状的差异也很大。只有花序密度与昆虫数量和物种丰富度呈显著正相关。这些结果表明,培育和使用能产生更多花序的红三叶草栽培品种可以提高红三叶草对传粉昆虫的价值。我们注意到,昆虫来访的数据很容易收集,可以提供给农民,帮助提高红三叶草田对传粉昆虫的价值。

期刊介绍: Agricultural and Forest Entomology provides a multi-disciplinary and international forum in which researchers can present their work on all aspects of agricultural and forest entomology to other researchers, policy makers and professionals. The Journal welcomes primary research papers, reviews and short communications on entomological research relevant to the control of insect and other arthropod pests. We invite high quality original research papers on the biology, population dynamics, impact and management of pests of the full range of forest, agricultural and horticultural crops.
