摘要
Food security is one of the top priorities of sustainable development. Conventional intensive agriculture provides high crop yields of important food staples such as wheat and rice, but comes with severe environmental impacts. Intercropping, the mixed cultivation of crop species on the same land, is traditionally and widely practiced by small-holder farmers world-wide in various ways, using a diversity of crop combinations, temporal and spatial arrangements, and at different levels of fertilizer input. There is considerable evidence that intercropping can increase efficient use of land, light, water and nutrient use, suppress weed growth, reduce pest and disease, enhance soil carbon sequestration and soil fertility, and enhance yield stability and farmers’ profitability (Stomph et al., 2020).
