Plastic trimming
After the apricot tree is harvested, open the branches and open the branches to ease the tree's vigor and promote flowering; take measures such as pinching and twisting the new shoots twice to promote branching and cultivate branch groups. The fruiting branches that are significantly weakened and drooping after the result should be properly retracted. For the extra-long branches that sprout in the canopy, if there is room for growth, take measures such as topping and twisting the tips to control their vegetative growth; for the extraordinarily long branches without growth space, timely remove them. At the same time, cut off the dead branches, split branches, diseased and insect branches, cross branches, overlapping branches, and weak branches in the crown to reduce nutrient consumption of the tree body and improve the ventilation and light conditions of the tree body to facilitate the formation of high-quality flower buds.
Fertilizer management
After harvesting, it should be combined with weeding in the whole garden to loosen the soil. Generally, the depth of tillage is about 10 cm. Combine basal fertilizer and deep plowing before falling leaves, with a depth of 30-40 cm.
Fertilizer should be applied as soon as possible after harvest, especially for trees with weak tree vigor and more fruit in the year, and fertilization should be timely to make up for the consumption of nutrients in the tree. A quick-acting fertilizer was applied immediately after the apricot trees were picked, and 0.5 kg of urea was applied to each mature apricot tree, and then watered. Combined with spraying, foliar spraying and spraying a mixture of 0.3% potassium dihydrogen phosphate and 0.2% urea can increase the nutrient accumulation of the tree and increase the number and quality of flower buds. From late August to early October, base fertilizer is applied, mainly high-quality farmyard manure, mixed with a small amount of phosphorus and potassium fertilizer. Generally, 30-50 kg of farmyard manure and 0.3-0.5 kg of superphosphate shall be applied to the first-fruit tree of 5-6 years old; 70-100 kg of farmyard manure and 0.5-1 kg of superphosphate shall be applied to each plant in the full fruit period. Watering immediately afterwards can increase the nutrient level of the tree body and keep the tree vigorous after harvest to ensure the yield in the coming year.
After harvesting, watering in time for the first time can ensure the normal differentiation of flower buds and the growth, aging and maturity of branches. If it is rainy during this period, do not water it. At the same time, attention should be paid to drainage. In the rainy season, if there is accumulated water, it should be removed in time to prevent the apricot tree from being infected by waterlogging and affecting the growth and development of the tree. Pour the frozen water well, and in places where conditions permit, pour thoroughly water once before freezing to ensure the safe overwintering of apricot trees.
Pest Control
Apricot trees are often harmed by pests and diseases after picking fruits. Spraying pesticides should be used to protect the leaves and increase the nutrient accumulation of the tree. Timely control aphids, red spiders, sky caterpillars, boat-shaped caterpillars, apricot disease, bacterial perforation and other pests.
