Weed management using synthetic herbicides is undergoing a global decline, necessitating a re‐evaluation of existing control measures and the development of novel weed management tools. ‘Mini‐ridging’ is a non‐discriminatory, physical weeding method that functions by burying weeds in the intrarow with a laterally shifted ridge of soil. In glasshouse trials using potted plants, we found that plant recovery after soil application was influenced by plant size, which in turn was influenced by plant species, developmental stage and/or age. The likelihood of plant recovery after soil application was negatively related to the depth of soil applied: very few plants survived total coverage by soil but, conversely, survival could be substantial if some parts of the plants were not covered. The results suggest that burial under a depth of 6 cm of soil would eliminate most plants regardless of species or growth stage. Larger plants would require the application of a greater total depth of soil to achieve this 6 cm of soil cover, and weed management would, therefore, tend to be more successful and more practical if weeds were targeted when still small. This research demonstrates the potential of plant burial as a simple and reliable means of non‐chemical weed management, and re‐emphasises that, for weed control to be effective, the applied soil layer must cover the whole plant.

控制行内杂草的微型垄的潜力：估计最小致死埋藏深度

使用合成除草剂的杂草管理正在全球范围内下降，需要重新评估现有的控制措施并开发新型杂草管理工具。“迷你垄”是一种非歧视性的物理除草方法，其功能是将杂草埋在带有横向移动的土壤垄的行内。在使用盆栽植物的温室试验中，我们发现土壤施用后的植物恢复受植物大小的影响，而植物大小又受植物种类、发育阶段和/或年龄的影响。土壤施用后植物恢复的可能性与土壤施用的深度呈负相关：很少有植物能够完全被土壤覆盖，但相反，如果植物的某些部分未被覆盖，则存活率可能很高。结果表明，无论物种或生长阶段如何，埋在 6 厘米深的土壤中都会消灭大多数植物。较大的植物需要施用更大的土壤总深度才能达到这 6 厘米的土壤覆盖层，因此，如果在杂草还很小的时候就将其作为目标，杂草管理往往会更成功和更实用。这项研究证明了植物掩埋作为一种简单可靠的非化学杂草管理手段的潜力，并再次强调，为了有效控制杂草，施用的土壤层必须覆盖整个植物。如果在杂草还很小的时候就将其作为目标，往往会更成功、更实用。这项研究证明了植物掩埋作为一种简单可靠的非化学杂草管理手段的潜力，并再次强调，为了有效控制杂草，施用的土壤层必须覆盖整个植物。如果在杂草还很小的时候就将其作为目标，往往会更成功、更实用。这项研究证明了植物掩埋作为一种简单可靠的非化学杂草管理手段的潜力，并再次强调，为了有效控制杂草，施用的土壤层必须覆盖整个植物。
