Peach and plum trees grow relatively quickly, especially in flatlands and floodplains within our city. With proper care, they can be planted, flower, and bear fruit within a short period—often achieving tree growth in the same year, flowering in the same year, and producing fruit by the second year. If the soil is rich in nutrients, their growth rate can be even faster, but without careful management, they may become too vigorous and unmanageable. Therefore, controlling the canopy and encouraging early fruiting is crucial for their healthy development.
In the first year after planting, the key strategy is "promote first, then control." This is essential for ensuring early fruit production. The "promotion" phase refers to accelerating the growth of young seedlings during the 4th to 7th months after planting, allowing them to complete all necessary nutrient growth for high yield. The "control" phase involves managing vegetative growth from mid-July onward, encouraging the tree to shift toward reproductive growth and develop sufficient flower buds for future harvests. To achieve this, immediately after planting, set a trunk height of 30–50 cm, maintain a natural tree shape, and keep 3–4 main branches on the trunk. When new shoots reach about 30 cm, prune them to encourage branch development. In early July, reduce water and fertilizer inputs. Mid-month, spray the entire orchard with 15% paclobutrazol diluted 100–250 times, and repeat the treatment after two weeks for better results. Adjustments can be made based on tree condition and flowering performance.
For trees that are growing too vigorously or have large branches, stop applying nitrogen fertilizers immediately and spray the entire orchard with 15% paclobutrazol at a dilution of 100–250 times. For strong trees, use 100–150 times; for weaker ones, use 200–250 times. Repeat the spray after two weeks and adjust as needed to prevent new leaf growth and promote flowering. Increase pruning efforts by removing large branches and thinning out dense areas.
Pruning should mainly be done during summer, with some winter cuts as a supplement. Light pruning helps open up the tree structure. Techniques like topping and spreading branches are effective. Typically, 3–4 prunings per year help shape the canopy quickly. During winter, shorten long branches and fruiting spurs, while extending middle and short branches. Remove overly vigorous and dense branches on the upper and outer parts of the tree, along with leggy, diseased, or weak branches.
Fertilizer and water management is also important. In the first year, saplings should receive light and frequent applications, ideally 1–2 times per month from March to May. Nitrogen-based fertilizers should be used in combination with phosphorus and potassium to support shoot growth and structural development. Later, focus on controlling vegetative growth and promoting flower bud formation. Avoid using nitrogen-rich fertilizers after July. Once the tree enters the high-yield stage, apply organic fertilizers in autumn and compound fertilizers from October to November, using about 50 kg of compost per plant. After fruit set, apply manure or nitrogen-based fertilizers, and add phosphorus and potassium during the hard core stage, while keeping nitrogen levels under control. Drainage should be ensured during rainy seasons.
Pest control is critical. Use a mix of long-acting and short-acting agents, combining preventive and curative measures. Employ high-efficiency, broad-spectrum, low-toxicity pesticides and biological controls to meet green food standards. Pay special attention to diseases like anthracnose, gummosis, brown rot, borers, and fruit flies. (Hubei Dangyang Agricultural 110 Service Center)
