Five key points in the management of apricot trees after unloading fruit

After a large number of fruit hanging, topdressing apricot tree consumes a lot of nutrition, and after fruit removal is the period of flower bud differentiation, it needs adequate nutrition supply. Therefore, fertilizer should be applied in time and nutrition should be replenished in time. Clear orchard combined with topdressing to clean up the weeds, fallen leaves, rotten fruits, diseases and insect pests in the orchard in time and bury them deeply to prevent the spread of diseases and insect pests and eggs. Insecticidal apricot trees are most likely to give birth to red spiders. After red spiders harm their leaves, they will cause early defoliation and affect flower bud differentiation, resulting in less flowers, less fruits and low yield in the coming year. The red spider can be treated with 1000-fold solution of 15% chlorpromazine or 1.8% avermectin 3000-4000 times. In summer pruning, erect branches, cross branches, overlapping branches, disease and insect branches and weak branches should be cut off in order to reduce the nutrient consumption of trees. For trees with small opening angles, you can use ropes to pull branches, or bricks and stones to fall branches. After apricot fruit harvest, the apricot fruit should be ploughed in the whole garden, combined with fertilization. Through deep ploughing, the soil structure can be improved, the root growth can be promoted, the cold resistance can be improved, and the overwintering base of pests can be reduced. [
