How to Manage Pear Trees After Picking? Detailed Explanation of the Latest Key Points
Autumn is the season when pear tree fruits ripen. Generally, September to October is the season for picking and harvesting pears, and in order to lay a solid foundation for a bumper harvest the following year, the management key points after picking are extremely important. If management is not done properly, it is very easy for branches to become weak, for pests and diseases to become serious, and for flower bud differentiation to be affected, which has a very obvious impact on the following year's yield. So how should pear trees be managed after picking? Let's take a look.
1. Pruning and Clearing the Orchard
After picking, the first thing to do is clean up the remaining branches and fallen leaves, prune the remaining damaged fruit and bad fruit, cut off diseased branches and diseased leaves, cut off the dense small branches with relatively strong growth, and appropriately thin out the spacing between branches and leaves to ensure good ventilation and air flow. When the leaves have basically all fallen, promptly remove the fallen leaves, remaining branches, and weeds, and bury them deeply in a centralized place or burn them. This can not only eliminate overwintering pests and diseases, but also increase orchard fertility. In addition, when pruning, branches with borer holes or insect eggs, dead branches, dead buds, and mummified fruit can all be cut off together and burned in a centralized place.
2. Soil, Fertilizer, and Water Management
After pear trees are picked, the soil should be deeply turned in a timely manner. There are many overwintering pathogens and pests in the soil. During their dormant period, turn the soil deeply to expose them on the ground surface or turn them deep into the soil so that they cannot emerge and cause harm. In addition, carry out shallow tillage and shallow turning of the soil within the drip line of the tree canopy in a targeted way. Soft and breathable soil is beneficial to fruit tree growth. After turning the soil, dig fertilizer trenches along the way, apply sufficient base fertilizer in the trenches, and maintain sufficient fertility to provide nutrients for the plants to overwinter and for flower bud differentiation the following year. After fruit picking, it is also necessary to do a good job of drought resistance and waterlogging prevention. Water and moisture can be conserved by covering with dry grass, preventing drought and draining excess water.
3. Disease Prevention
After pear trees are picked, it is inevitable that a large number of mechanical wounds will appear, and at this time pathogens will have an opportunity to take advantage. Therefore, after picking, pear brown spot disease, gray spot disease, rust disease, and other pests and diseases are also very likely to appear. If not treated in time, they will cause physiological leaf drop and hinder the growth of the fruit trees. Therefore, after picking, a 0% thiophanate-methyl wettable powder 800—1000 times solution or a 7-use 0% mancozeb wettable powder 600 times solution can be sprayed, which can effectively prevent and control pests and diseases. It can also be combined with foliar fertilizer spraying of a mixed solution of 0.3% urea and 0.3% potassium dihydrogen phosphate, which can restore normal growth of branches and leaves.
