Introducing cover crop (CC) mixtures is a promising approach to enhance the multifunctionality of ecosystem services provided by CCs. However, CC mixtures have contrasting effects on subsequent crop yield, depending on multiple factors such as the type of subsequent crop and the mixture composition. In the context of climate change, sunflower (Helianthus annuus L.), which is adapted to environments with low nitrogen (N) and water requirements, has multiple varieties with different drought-tolerance strategies. However, little is known about how drought-tolerant sunflower varieties differ in their response to CCs in low-input systems.

向日葵品种的表型性状取决于覆盖作物的组成


引入覆盖作物 （CC） 混合物是增强 CC 提供的生态系统服务的多功能性的一种有前途的方法。然而，CC 混合物对后续作物产量的影响截然不同，这取决于多种因素，例如后续作物的类型和混合物成分。在气候变化的背景下，适应低氮 （N） 和低水需求环境的向日葵 （Helianthus annuus L.） 有多个品种，具有不同的耐旱策略。然而，对于耐旱的向日葵品种在低投入系统中对 CCs 的响应有何不同，人们知之甚少。
