摘要： Several organic (e.g., compost, hay, straw, grass) and inorganic (e.g., plastic film) ground cover (GC) forms are used in peach orchards worldwide. Yet, there is a lack of quantitative studies on peach orchard ecosystem services comprising fruit yields and quality, soil health indicators, and biological pest control. To fill this knowledge gap, we performed a meta-analysis of 55 peer-reviewed research. Overall, inorganic GC increased peach yields by 7.7 +/- 1.8%, while organic GC reduced it, though not statistically significant (p > 0.05), by 1.7 +/- 3%. Both forms of GC have enhanced single fruit mass, with a greater increase in inorganic (4.2 +/- 1.7%) than in organic GC (1.2 +/- 1.2%), and soluble solids content by 5.9 +/- 0.9% and 3.2 +/- 0.7%, respectively. Inorganic GC did not significantly affect titratable acid and fruit hardness, while organic GC reduced titratable acid (13.7 +/- 2.1%), and fruit hardness (89 +/- 2.9%). Soil temperature has increased in orchards with inorganic GC (2.8 +/- 2.9%) and reduced with organic GC (8.3 +/- 2.4%). Inorganic GC marginally increased soil water storage, while organic GC increased it by 9.3 +/- 2.1%. Both organic and inorganic GC increased soil water content by 13.1 +/- 2.4% and 26.1 +/- 3.4%, respectively. Unlike inorganic GC, organic GC increased soil organic matter, available nitrogen, available phosphorus, and available potassium by 28.3 +/- 3.3%, 25.1 +/- 2.7%, 23.5 +/- 4.6%, and 30.9 +/- 3.3%, respectively. Equally significantly, organic GC increased predator abundance (47.5 +/- 5.9%) and reduced pest incidence (2.4 +/- 1.8%). Overall, inorganic GC systems slightly increased peach yield but are not sustainable due to their negative soil health and environmental impacts. In contrast, organic GC systems delivered an acceptable yield level while providing numerous ecosystem services, enabling sustainable long-term peach production.
