本文基于广东梅州地区气候及土壤条件，从选地建园等方面总结了西施柚高产栽培技术。选择向阳、水源充足的砂质壤土，深挖种植穴并施入腐熟粪肥、豆麸、磷粉及微生物菌肥，以改良土壤。以酸柚为砧木，采用枝接或芽接法培育壮苗，并于春季或秋季按行距4.5 m、株距3.5 m的密度定植。在土壤、肥料及水分管理上，幼树以高氮有机肥促进树冠形成，成年树根据春梢萌发、果实膨大等不同时期精准追施高氮、高钾及有机肥，并结合深翻扩穴、间作绿肥、覆盖树盘及排水灌溉等措施维持土壤活力与水分平衡。整形修剪方面，幼树及时打顶定干，结果树在采果后疏剪重叠枝、病虫枝等，同时辅以多效唑等植物生长调节剂。花果管理遵循去弱留强原则，确保叶果比在（200～300）∶1。病虫害防治采用物理、生物防治相结合的方法，通过选用脱毒苗木、果实套袋以及在关键时期喷施高效低毒农药等措施综合防控。于10月中下旬果实达到成熟标准时采收，并经杀菌、分级和热缩膜包装等采后处理。本文为西施柚的推广种植提供参考。

Based on the climatic and soil conditions of the Meizhou region in Guangdong, the high yield cultivation techniques for Xishi pomelos were summarized, covering aspects such as site selection, orchard establishment. Sandy loam soil with good sunlight exposure and a reliable water source was selected. Planting holes were dug deep, and decomposed farmyard manure, soybean meal, phosphate powder, and microbial fertilizer were applied to improve soil conditions. Seedlings were grafted onto sour pomelo rootstocks using branch grafting or bud grafting to cultivate robust plants, and they were planted in spring or autumn at a spacing of 4.5 meters between rows and 3.5 meters between plants. In terms of soil, fertilizer, and water management, high-nitrogen organic fertilizer was applied to young trees to promote canopy formation. For mature trees, precise topdressing with high-nitrogen, high-potassium, and organic fertilizers was carried out during different growth stages, such as spring shoot germination and fruit expansion. Additionally, measures such as deep plowing and hole expansion, intercropping with green manure crops, mulching of tree disks, and drainage and irrigation were implemented to maintain soil vitality and water balance. In terms of pruning and shaping, young trees should be topped and dried in a timely manner. As a result, the tree should be pruned after harvesting, including overlapping branches, diseased and insect infested branches, and supplemented with plant growth regulators such as paclobutrazol. For flower and fruit management, the principle of removing weak flowers and fruits while retaining strong ones was followed, ensuring a leaf-to-fruit ratio of (200-300)∶1. Disease and pest control was primarily based on physical and biological methods, supplemented by the use of virus-free seedlings, fruit bagging, and the application of highly effective, low-toxicity pesticides during critical periods. Fruits were carefully harvested in mid-to-late October when they reached maturity. Post-harvest treatments, including sterilization, grading, and heat-shrink film packaging.
