Carry out pruning well. After harvest, summer pruning should be carried out, cutting off dry and broken branches, and appropriately retracting the fruiting branches that have significantly weakened and drooped after fruiting; for vigorous shoots sprouting inside the canopy, if there is growing space, measures such as pinching and twisting should be taken to control vegetative growth; if there is no growing space, they should be removed promptly. Strengthen soil and fertilizer management. First, after the apricot fruit is harvested, the soil should be loosened by shallow cultivation immediately, generally to a depth of 5-10cm. Before leaf fall, deep plowing should be carried out in combination with applying base fertilizer, preferably 30-40cm. Second, a quick-acting fertilizer should be applied promptly, with 0.5 kg of urea applied to each mature tree, followed by immediate watering. Apply base fertilizer once before leaf fall in autumn. Finally, because apricot trees are not tolerant of waterlogging, if there is standing water in the apricot orchard during the rainy season, it should be drained promptly to prevent disease caused by waterlogging.
