Highlights • Farmyard manure increased earthworm populations more than straw in the field.• Milled straw increased earthworm growth more than milled manures in microcosms.• Earthworm growth rates are positively correlated with amendment calorific value.• Straw only benefits earthworm growth when milled.• Incorporating milled straw in arable soils may increase earthworm populations.

磨碎的谷物秸秆比选定的有机添加物更能加速蚯蚓 (Lumbricus terrestris) 的生长

亮点 • 农家肥比田间秸秆更能增加蚯蚓种群。• 在微观世界中，磨碎的秸秆比磨碎的肥料更能促进蚯蚓生长。• 蚯蚓生长率与修正热值呈正相关。• 稻草只有在磨碎时才有益于蚯蚓的生长。• 掺入在耕地中磨碎的秸秆可能会增加蚯蚓的数量。
