Detailed Explanation of Key Technical Points for Soil, Fertilizer and Water Management in Apple Orchards
1. Soil management For the soil management of mature fruit tree orchards, the clear-root method or tree-disk mulching method should be adopted. From spring to before the rainy season each year, after combining fertilization and irrigation, carry out intertillage and loosening of the soil. Weed 1-2 times to keep the soil loose and free of weed growth. In the rainy season, cut grass and cover the tree disk 1-2 times. In autumn, after the fruit trees shed their leaves, carry out autumn plowing. Use an iron shovel to deep-turn the tree disk to 15-20 cm, then apply additional organic fertilizer. Apply topdressing three times, respectively before and after sprouting, after flower drop, and during the fruit enlargement stage, using nitrogen, phosphorus and potassium elements in combination. The ratio is 1:0.6:1.5.
