Apple sweetness is a key factor that influences consumer satisfaction. To achieve better sweetness and color in apples, several effective methods can be applied. Here are some detailed techniques: (1) Use reflective film. In early August, place aluminum foil plastic around the tree canopy, about 1 meter high. This reflective material helps increase light exposure, improving fruit color, especially on the inner parts of the tree and lower fruits. Trees treated with this method showed 71% red or partially red fruits, compared to just 40% in untreated trees. (2) Apply bacterial agents. Using a sweetening agent not only boosts sugar content but also enhances color uniformity while maintaining the fruit’s natural green quality. These agents are safe and environmentally friendly, making them ideal for organic farming. (3) Practice proper fertilization. Red Fuji apples require high potassium levels. Applying extra potassium fertilizer after July can improve the coloring index by 24.4% and increase sugar content by 2.4% in absolute terms. (4) Fruit bagging. Bagging helps protect the fruit from sunburn and improves color development. It's recommended to use double-layer waxed paper bags that offer good shading, air circulation, and water resistance. Bags should be placed before harvest and removed 15–20 days before picking. Spraying water 1–2 times during this period can further enhance color. (5) Prune leaves, twist fruits, and support branches. Remove leaves that block sunlight from reaching the fruit. For fruits that are not fully colored, gently twist them to expose the shaded side to sunlight. Install supports like poles and hanging sticks in the later growth stages to prevent branches from overlapping or sagging, which can hinder color development. (6) Place reflective film in the orchard. After pruning and twisting fruits, lay reflective film under the trees. This technique significantly improves the color of the lower parts of the tree and increases the overall red fruit ratio. These methods, when combined, can greatly enhance apple sweetness and appearance. For more information or detailed guidance, visit our website or contact us directly.
