Scope

Main technical content: 5.1 Site conditions: Sloping land and flat land with a slope of less than 25°. The soil type is red soil, with an organic matter content of ≥1.5% and a pH value of 5.0 to 6.5. 5.2 Seedling propagation: Using sour pomelo as the rootstock, grafting branches from excellent mother trees. 5.3 Cultivation management: Planting in spring and autumn, with a planting spacing of 5m×4m or 5m×5m, and planting rows oriented north-south or on contour lines. Evenly distribute 5% to 8% pollinating trees such as sour pomelo and Guanxi honey pomelo in the orchard. Soil management: Starting from the second year after planting, deep plowing and soil improvement are carried out. Organic fertilizers such as green manure, straw, and manure are applied in layers at 80kg to 100kg per cubic meter. Lime is applied 1 to 2 times per hectare. For flat land orchards, soil is gradually raised and ridges are formed over the years. Shaping and pruning: Measures such as bud removal, shoot control, shortening branches, thinning, and line-guided shaping are used to cultivate a natural open-crown tree crown. Fertilization: For young trees, "one shoot, two fertilizations" are applied, with nitrogen as the main nutrient and a nitrogen-phosphorus-potassium ratio of 1:0.3:0.7. For fruiting trees, organic fertilizers are the main fertilizer, with an annual application of no less than 10,000kg per hectare. Inorganic fertilizers and trace elements are also applied rationally, with a focus on promoting shoot and flower growth, strengthening shoot and fruit growth, and harvest fertilization. The nitrogen-phosphorus-potassium ratio is 1:0.5:0.8, and based on a yield of 100kg pomelo per tree, the total annual nitrogen application is about 3.0kg. Water management: Based on the growth characteristics of young and fruiting trees, reasonable irrigation and drainage are carried out. Pest and disease control: Pest and disease prevention and control are carried out in accordance wit
