Matters needing attention in post-harvest management of the latest apricot trees

Apricot trees consume a lot of nutrients after hanging a large amount of fruit, and face flower bud differentiation after fruit picking, so they need a lot of nutrition supply, so they need timely fertilization and supplement the consumed nutrients in order to have sufficient nutrients for flower bud differentiation. But in addition, we also need to pay attention to the following aspects, let's take a look.

1. Pruning

Apricot trees must be pruned once after fruit harvest, cut off the dry and withered branches and split branches, retract and prune the weak and drooping branches after fruiting, and take measures such as coring and twisting in time to restrain their vegetative growth, and erase all the branches that have no room for growth so as not to cause unnecessary nutrient consumption. Erect branches, crossed branches, overlapping branches, disease and insect branches and weak branches should be cut off in time to save nutrient consumption. for branches with a small angle, it is very easy to use the method of hanging branches or pulling branches to expand the angle to increase the crown width of the plant. lay a solid foundation for high yield and high yield.

2. Strengthen the management of soil and fertilizer

Apricot trees should be ploughed and loosened in time after fruit harvesting, and the general depth of intertillage is 5-10 cm. Base fertilizer should be applied in combination with deep ploughing before defoliation, and the suitable depth of base fertilizer is 30-40 cm. Fruit harvesting should be timely applied a quick-acting chemical fertilizer, each plant can be applied 0.5 kg of urea, watering. The base fertilizer of deciduous leaves in autumn is mainly to inhibit farm manure, with an appropriate amount of phosphorus and potassium fertilizer. In addition, apricot trees are not resistant to waterlogging, so it is necessary to remove stagnant water in time when the rainy season comes, so as not to become infected with disease or root rot. When fertilizing, clean up the weeds, fallen leaves, rotten fruits, diseases and insect pests in the orchard, bury them deeply or burn them, which can reduce the number of diseases and insect pests.

3. prevention and control of diseases and insect pests

During the period of high incidence of diseases and insect pests after fruit harvest, apricot trees should be sprayed reasonably according to the actual situation to protect their leaves and accumulate more nutrients. For aphids can be used to control aphids, red spiders will cause early defoliation of apricot trees, affecting the flower bud differentiation in the coming year, resulting in low yield in the coming year, which can be controlled with dacarine or avermectin.

4. Spray growth regulator

Paclobutrazol solution can be sprayed 1-2 times after apricot fruit harvest, and mixed with low concentration urea solution and potassium dihydrogen phosphate solution, which can promote flower bud differentiation. Before the soil is frozen in autumn and winter, it is very easy to pour frozen water once to ensure that apricot trees survive the winter safely.
