As late August approaches, apple trees begin to enter the harvest season. Not only early-maturing varieties are ready for picking, but mid and late-season apples also start to show color and prepare for harvest. To ensure a successful harvest and maintain tree health, the following management practices should be carried out during this period: 1) Due to increased rainfall in the previous weeks, weeds have grown rapidly, leading to excessive ground cover in orchards. This overgrowth hinders air circulation, increases the risk of disease, and interferes with the application of reflective mulch. It is recommended that growers clear the ground of weeds before bagging to improve airflow and prepare the orchard for proper mulch placement. 2) The combination of high temperatures and humidity, often caused by prolonged drought, has led to early leaf drop in some orchards. There are two main causes: one is improper pre-treatment, which resulted in premature leaf loss in certain trees. Growers are advised to continue pruning in autumn to enhance light penetration and air circulation. Alongside regular treatments, it's important to combine medication with nutritional supplements and physiological color enhancers. The second cause is related to inadequate disease control earlier in the season, leading to leaf drop from incorrect pesticide use. In such cases, immediate pruning and spraying are necessary to protect remaining leaves, ensuring healthy fruit development and flower bud formation later on. 3) After removing the bags, it’s essential to prune branches and thin out dense foliage to promote better fruit coloring. Some shade-blocking leaves should also be removed to reduce the need for post-bag removal leaf picking. Once pruned, all fallen branches should be cleared from the ground, and the surface should be leveled to ensure proper placement of reflective mulch. 4) When conditions are favorable (in terms of timing, weather, and market demand), it’s crucial to remove the bags quickly and efficiently. Avoid doing it gradually, as rapid and uniform coloring is key to achieving consistent fruit quality and maximizing market value. Immediately after bag removal, lay the reflective mulch. Following the 2009 May 16 disaster, it was determined that paper bagging should be used in specific areas. After securing the market, remove the bags and apply reflective mulch to enhance fruit appearance and increase sales price. After spraying, apply an additional treatment containing calcium to prevent microbial infections. Two to three days later, manually remove the leaves around the fruit twice and rotate the less-colored fruits by at least 90 degrees. Harvest in batches once the market price is favorable, avoiding multiple harvests that could lead to price drops. 5) After harvesting, it’s important to re-prune the trees to delay leaf fall and help accumulate organic nutrients. Apply a good quality fertilizer to replenish what was lost during fruiting, restore tree vitality, and prepare for next year’s harvest. In summary, this period is a critical test of the overall effectiveness of orchard management throughout the year. A thorough understanding of market trends and timely, efficient sales are even more crucial. If high-quality apples are not sold well, it can significantly impact the motivation and success of orchard operations. Therefore, staying informed about market conditions, managing every detail carefully, and striving for the best possible returns this season is essential.
