Scope

Main Technical Content: 6. Planting 6.1 Seedling Cultivation 6.1.1 Use natural seedlings of plum trees as rootstocks, and avoid using natural seedlings of peach or apricot trees. 6.1.2 Select high-quality varieties such as salt plum, bitter plum, and Zhaoshui plum. 6.1.3 For flat or gently sloping land with good soil conditions, use a planting spacing of 4m × 4m, with 42 plants per 667m2; for sloping land, use a planting spacing of 3m × 4m, with 55 plants per 667m2. 6.1.4 Mark the planting location with a string according to the set planting spacing, ensuring rows are straight and horizontal. The planting pit should be 80cm × 80cm × 80cm in length, width, and depth. When digging the pit, separate the topsoil from the subsoil and apply 25kg–30kg of organic fertilizer to each pit. After mixing the soil and fertilizer, backfill the pit 20cm–30cm above ground level and create a circular tree disk. 6.1.5 Determine the planting position in the center of the planting pit. Dig a 30cm-deep and 40cm-wide planting hole. Unwrap the seedling and uprightly place it in the planting hole, ensuring even root distribution. Cover the roots with soil, gently lift the seedling to expose the grafting union, and water it thoroughly before covering with a plastic film. 6.2 Field Management 6.2.1 In the second year after planting, combine autumn base fertilization with pond expansion and soil improvement. Dig pits along the drip line of the crown and backfill them with organic fertilizer, accounting for 70% of the annual application amount, gradually transferring it outward as the crown expands each year. 6.2.2 Maintain loose and weed-free soil within the tree disk. In the first–third years after planting, intercrop vegetables, short-stemmed legumes, or green manure between rows. Select green manure or pasture grass species and implement full-field grassing or inter-row strip grassing. 6.2.3 Base fertilization: Apply 50kg of composted organic fertilizer and 0.2kg of sl
