T/ZLX 002-2020 Green food Wencheng Yangmei production technical specifications

Scope

Main technical content: Selecting ecologically favorable areas with good environmental quality, far from pollution sources, with slopes less than 30° and altitudes below 700 m for slope and mountainous areas to establish orchards. Requirements include sufficient sunlight, abundant rainfall, good drainage, soil pH of 4.5–6.5 with slightly acidic, gravel-containing sandy soil, an average annual temperature of over 14°C, and an absolute minimum temperature of no less than -9°C, with an annual accumulated temperature of over 4,500°C. The production environment should meet the requirements of NY/T 391. 5. Cultivation and Management 5.1 Seedling transplantation can be divided into spring planting and autumn planting. Spring planting is from late February to mid-March, and autumn planting is from early October to early November. Spring planting is preferred. Choose a windless overcast day for planting, with planting density determined based on the site conditions and management level of the orchard plot, with a spacing of 5 m × 6 m or 6 m × 6 m, resulting in 18–22 trees per mu. The planting pit should be 100 cm × 100 cm × 80 cm deep. 5.2 Shaping and Pruning 5.2.1 Young tree shaping adopts the natural open crown form. The height of the stem is 20–30 cm, with 3–5 main branches, and the angle between the main branches and the trunk should be greater than 45°. On the main branches, equip 3–4 secondary branches in different directions, and cultivate fruiting branches on these branches. Methods such as bud removal, pinching, branch pulling, shortening, and pruning are used to ensure a moderate density and orderly distribution of branches, forming a good structure for high and stable yield. 5.2.2 Fruit-bearing tree pruning appropriately removes overly dense, upright, and crossed branches, as well as diseased and pest-infested branches. Gradually remove central upright large branches to open up the crown, promote healthy branch growth, and ensure good ventilation and lig
