摘要

High-density planting (HDP) has emerged as a transformative orchard management strategy designed to enhance yield, land-use efficiency, and profitability across major fruit crops. This manuscript systematically synthesizes and critically evaluates empirical evidence comparing HDP with conventional orchard systems in apple (Malus domestica), mango (Mangifera indica), citrus (Citrus spp.), guava (Psidium guajava), and banana (Musa spp.) production. The review integrates multi-location field trials, meta-analyses, and economic assessments conducted over the past two decades. Results demonstrate that HDP generally accelerates fruiting, improves light interception and canopy management, and increases cumulative yield, although the magnitude of gains ranging from 30% to 200% varies by species, rootstock, agroclimate, and management intensity. Economic analyses indicate higher gross returns, improved benefit–cost ratios, and shorter payback periods for HDP relative to conventional orchards; however, these advantages depend on rigorous canopy management, fertigation, and pest control. Potential limitations, including increased disease risk under dense canopies and variability in long-term orchard performance, are also discussed. The review identifies critical knowledge gaps, comprising long-term impacts on soil health, orchard lifespan, and climate resilience, and highlights opportunities for integrating mechanization, digital monitoring, and species-specific HDP models. Overall, HDP represents a scientifically validated and economically viable approach to sustainable orchard intensification, with adoption particularly valuable in regions facing land scarcity, labor constraints, and increasing demand for high-quality fruit.
