Scope

Main technical content: 5.1 Site Conditions: Slope lands and flat lands with an inclination of less than 25°. The soil type is red soil, with an organic matter content ≥ 1.5% and a pH value between 5.0 and 6.5. 5.2 Seedling Propagation: Using sour pomelo as the rootstock, grafting with scions from excellent mother trees. 5.3 Cultivation Management: Planting time is in spring and autumn, with planting specifications of 5m × 4m or 5m × 5m, and rows planted in a north-south orientation or at the same elevation. Within the orchard, 5% to 8% of pollinating trees such as sour pomelo and Guanxi honey pomelo are evenly distributed. Soil management: Starting from the second year after planting, deep tillage and soil improvement are carried out. Organic fertilizers such as green manure, straw, and manure are applied in layers at 80–100 kg per cubic meter. Calcium is applied 1–2 times per hectare. For flat-land orchards, soil is gradually raised and terraces are constructed each year. Shaping and pruning: Through measures such as bud removal, shoot control, shortening, thinning, line-shaped pruning, and trimming, a natural open-crown tree canopy is cultivated. Fertilization: For young trees, "one shoot, two fertilizations" are implemented, with nitrogen as the main component and a nitrogen-phosphorus-potassium ratio of 1:0.3:0.7. For fruiting trees, organic fertilizers are the main source, with an annual application of at least 10,000 kg per hectare. Inorganic fertilizers and trace elements are rationally applied, with emphasis on promoting shoot and flower growth, strengthening shoots and fruits, and harvest fertilizers. The nitrogen-phosphorus-potassium ratio is 1:0.5:0.8, calculated based on a yield of 100 kg per tree, with a total annual nitrogen application of around 3.0 kg. Water management: Based on the growth characteristics of young and fruiting trees, irrigation and drainage are carried out rationally. Pest and disease control: Pest and disease preven
