Abstract
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.This article provides a reference for the promotion and cultivation of Xishi pomelo.关键词
