摘要： Increasing agricultural biodiversity by diversifying crops or by co-culture of crops and aquatic animals has been widely recognised as a way to promote ecological intensification of crop production and reduce the use of pesticides. However, the potential of multi-trophic-level production systems, such as the co-culture of vegetables, flowers and aquatic animals, has received little attention. We performed a two-year experiment comparing multispecies (cauliflower, taro, flowers and aquatic animals) co-culture, and mono-cauliflower farming practices on the Chongming Eco-island of China. The abundance of herbivorous insects and their predators, pesticide input and cauliflower yield were recorded. The results indicated that multispecies co-culture decreased the abundance of insect herbivores by 19.9-26.0% and thus decreased pesticide use by 22.2-30.0%. Meanwhile, we found that co-culture of crops, flowers and aquatic animals increased the abundance (29.5-34.1%), and species diversity of invertebrate predators (3.3-3.8%), and increased cauliflower yield (6.9-7.5%). There were significant positive relationships between the abundance, species richness (or diversity) of arthropod predators and cauliflower yield. Multispecies co-culture has great potential to promote ecological intensification of vegetable production and the associated ecosystem services. (C) 2020 Elsevier Ltd. All rights reserved.
