Key points of post-harvest management of pear trees

Autumn is the season of pear fruit ripening, and it is generally the season of pear picking and harvest from September to October. In order to lay a solid foundation for high yield in the coming year, the key points of management after picking are very important. If the management is not in place, it is easy to appear branch weight, serious diseases and insect pests and affect flower bud differentiation, which has a very obvious impact on the yield in the coming year. So how to manage pear trees after picking? Let's take a look.

1. Pruning and clearing the garden

After picking, we should first clean up the residual branches and leaves, trim the remaining residual fruit and bad fruit, cut off the diseased branches and leaves, cut off the dense branchlets with strong growth, and properly comb the spacing between branches and leaves to ensure good ventilation. When the leaves are basically finished, the fallen leaves and weeds should be removed in time and buried or burned, which can not only eliminate overwintering diseases and pests, but also increase the fertility of the orchard. In addition, in pruning, branches with wormholes or eggs, dead branches, dead buds and nuts can be cut off and burned centrally.

2. Soil, fertilizer and water management

It is necessary to dig deep into the soil in time after pear picking. There are many overwintering germs and pests in the soil. During the dormant period, they will be deeply turned over, exposed to the ground or deep into the soil, so that they can not be unearthed. In addition, shallow ploughing was carried out on the soil within the crown drip line, and the soft and breathable soil was beneficial to the growth of fruit trees. After turning the soil, we dug fertilization ditches and applied sufficient base fertilizer in the ditches to maintain sufficient fertility. Improve nutrients for plant overwintering and flower bud differentiation in the following year. In fruit picking, we also need to do a good job in drought and waterlogging prevention, and we can protect water and soil moisture by covering hay, and prevent drought and waterlogging.

3. Disease prevention

After pear picking, there will inevitably be a large number of mechanical wounds, and the bacteria will have the opportunity to take advantage of this, so pear brown spot, gray spot, rust and other diseases and insect pests are also very easy to appear in the picking. If it is not treated in time, it will cause physiological defoliation and hinder the growth of fruit trees. Therefore, after picking, you can use 0% methyl topiramate wettable powder 800 times liquid or 7% manganic potassium wettable powder 600 times liquid spray, which can effectively prevent and control diseases and pests. The mixture of 0.3% urea and 0.3% potassium dihydrogen phosphate can also be sprayed with foliar fertilizer to restore the normal growth of branches and leaves.
