Key points of apple tree management technology in September

September is a critical period for apple tree management. Reasonable management techniques can help apple trees grow healthily, increase yield and fruit quality, enhance tree vigor, and promote flower bud differentiation, laying a solid foundation for increasing the flowering rate, fruit setting rate, and high yield, stable yield, and high quality of fruit trees in the coming year. Here are the key points of apple tree management techniques in September.

1. Water management

In September, the temperature gradually drops, but an adequate supply of water is still needed. Water appropriately according to weather conditions and soil moisture, keeping the soil moist but not too wet. Avoid overwatering, which can lead to root hypoxia and disease. At the same time, pay attention to good drainage and avoid water accumulation.

2. Fertilization management

In September, apple trees are in the fruit expansion period and need adequate nutrient supply. Apply organic fertilizer and chemical fertilizer reasonably according to the soil analysis results and the growth conditions of the apple trees. Organic fertilizers can provide slow-release nutrients that aid in soil improvement and microbial activity. Fertilizers should be rich in phosphorus and potassium to promote fruit development and improve disease resistance. At this time, spray "Peng Da Taizong" or "Tian Liang Taizong" on the leaves at 1000ml per acre to promote balanced absorption of fruit nutrients, uniform coloring, increase yield and quality, and also allow the fruit to be put on the market earlier.

3. Thinning fruits and branches

During the fruit expansion period, apple trees may have too many fruits, resulting in small fruits or weak trees. Therefore, it is necessary to thin the fruits and retain an appropriate amount of fruits to ensure the size and quality of the fruits. At the same time, thinning and shaping of branches should be carried out, and branches that grow too densely should be pruned to maintain ventilation and light transmission of the crown, promote fruit photosynthesis and prevent and control diseases and pests.

4. Fruit bagging management

September is the time when apples are ripe, and it is also a good time to remove the bags from the fruits. Removing the bags can promote the ripening and quality of the fruit, and also make it easier to pick and sell. However, attention should be paid to proper timing and gentle operation to ensure the integrity and quality of the fruit.

5. Pick leaves and turn fruits

During the fruit expansion period, the apple tree has too many leaves, which can easily affect the light and ventilation conditions of the fruit. Therefore, it is necessary to remove leaves and turn them into fruits, that is, to remove some leaves to promote photosynthesis and sugar accumulation in the fruit. When picking leaves to transfer fruits, you should choose to remove leaves that are old, damaged by pests and diseases, or that block the fruit, and keep the healthy leaves to maintain a reasonable nutrient supply for the tree.

To sum up, the key points of apple tree management in September include water management, fertilization management, fruit thinning, branch thinning and shaping, fruit bagging management and leaf picking and fruit rotation. Reasonable management techniques can help apple trees grow healthily and increase yield and fruit quality. However, adjustments need to be made according to specific circumstances and management needs to be carried out in combination with actual conditions to ensure the healthy growth, high yield and high quality of apple trees.
