Postpartum Care of Kiwifruit Fruit Trees

Xixia County, located in the western part of the Nanyang Basin in southwest Henan Province, is a region known for its ideal conditions for kiwifruit cultivation. With a total area of 5.18 million mu and a forest coverage rate of 76.8%, the county benefits from abundant sunlight, sufficient rainfall, and distinct seasons—factors that make it one of the most suitable areas for growing high-quality kiwifruit. Historically, local farmers focused heavily on fruiting management but often neglected the care of the fruit trees after harvest, which had a negative impact on tree health and future yields. Proper post-harvest management is crucial for maintaining tree vitality and ensuring good production in the following year. After harvesting, kiwifruit trees are in a weakened state and require proper nutrition to recover. Most of the nutrients needed for next year’s growth, including flowering, fruit setting, and leaf development, come from reserves stored in the tree during the previous season. Therefore, effective "postpartum" management is essential. Based on the actual farming practices in Xixia County, several key strategies have been developed to improve the long-term productivity and quality of kiwifruit. First, water and fertilizer management should be strengthened. After harvest, the soil should be tilled to a depth of 5–10 cm, with deeper plowing (30–40 cm) done before the trees lose their leaves. Quick-release fertilizers such as urea (0.5 kg per tree) should be applied, followed by watering. In the fall, base fertilizers like farmyard manure mixed with small amounts of phosphorus and potassium can be used. It's also important to drain excess water in orchards during rainy seasons to prevent root damage. Foliar sprays can help regulate growth. A solution of paclobutrazol at 500 mg/L, mixed with 0.3% urea or 0.3% potassium dihydrogen phosphate, can be sprayed once or twice after harvest to promote balanced growth. Winter watering is also essential. Before the ground freezes, a thorough watering should be done to ensure the trees survive the winter safely. The amount of water depends on drought levels and tree age. Pest and disease control is another critical aspect. Regular pruning of dead or diseased branches, cleaning the orchard, scraping bark cracks, and applying whitewash to trunks can help reduce infection sources and protect trees from pests. Pruning is an important practice that should be carried out between 10 days after leaf fall and 20 days before the first frost. For newly planted saplings, a light cut is made to encourage strong growth. One-year-old trees should have their strongest shoots shortened, while older trees need more detailed shaping to maintain balance and productivity. For young trees (3–4 years old), the focus is on developing a strong structure, promoting long branches, and controlling fruit load to accelerate the onset of fruiting. For mature trees, pruning aims to update old branches, control bud numbers, and maintain consistent yields year after year. Finally, after winter pruning, branches and twigs should be tied up using a “8”-shaped pattern on wire supports. This helps maximize sunlight exposure, protect against wind damage, and maintain an organized canopy structure. These practices not only enhance tree health but also contribute to higher quality and more consistent kiwifruit production.
