FRUIT CROPS

The Station conducts breeding, conservation, and evaluation of regionally important fruit crops, including mango, pomelo, pitaya and longan. In cultivation research and industry extension, we have improved mango pollination techniques, developed slope-orchard management and export-oriented orchard guidance, and improved papaya scion-supply systems and greenhouse propagation methods.

To enhance Matou wentan productivity and fruit quality, we established branch-and-shoot management practices to increase the proportion of leaf-bearing inflorescences and stabilize fruit set; for Matou hongyu we developed production management and long-term storage protocols to reduce weight loss and maintain quality.

Investigations into mango gummosis and fruit discoloration have informed measures to improve external appearance; longan inflorescence thinning increases fruit set and soluble-solid content; and pineapple off-season scheduling, together with an electric quantitative injection device, mitigates concentrated harvest risk. For pitaya, a semi-mesh bag was devised to correct uneven solar-side coloration and facilitate maturity assessment.

 In response to climatic variability, we formulate pre-disaster preparedness and post-disaster recovery measures for papaya, mango and citrus, and provide technical assistance to export orchards and packing houses to optimize postharvest operations and equipment.
