As the temperature gradually decreases, pear trees enter a dormant period in December, and winter pruning should be carried out at this time. After the leaves of the pear trees have fallen, the planting of the newly planted pear trees will start. In order to ensure a good winter dormancy for pear trees, organic fertilizers should be applied as soon as possible. If the weather is dry, the field should be irrigated once to increase the ground temperature. ①Stay longer and release more, promote the combination of control, and focus on promoting; ② restrain the strength and promote the weak, combine the scaling, and focus on the release; ③ first cut and then release, balance the branch groups through pruning methods such as thinning, cutting, shrinking, and expanding Growth vigor; ④Look at the bud pruning, pay attention to the direction and quality of the buds, so as to facilitate the opening of the branch angles in the future; ⑤Cut less and more release, do not replace long release with long retention; ⑥Maintain growth, flower formation, and three results Proper proportion of planting branches; ⑦Adjust the angle of the branch group, and adjust the angle between 45 and 75 degrees according to the different growth and strength. The angle of strong branches should be large and the angle of weak branches should be small to maintain the growth potential of the branch group; ⑧Renew and rejuvenate the branch group in time, renew the strong branch renewal, maintain the moderate shrinkage, and remove the weak branch after the result. The pruning focus is different for different age, adult, and senescence pear trees. Pruning of young pear trees Saplings refer to pear trees that are 1 to 5 years old that have not fruited or have just begun to bear fruit. At this time, the pear tree is an important period for expanding or forming the crown. When pruning, the backbone branches should be selected and cultivated according to the selected target tree shape to form a strong and firm skeleton, and the fruiting branches should be properly cultivated to make the young tree expand the crown. At the same time, it can enter the fruiting period in time. Pruning of adult pear trees An adult pear tree refers to a tree whose crown is basically formed and has entered a large fruiting period. The task of pruning is to make the branches continue to extend and develop after the configuration of the backbone branches is completed; ease the tree vigor and increase the proportion of short and medium branches; regulate the relationship between vegetative growth and reproductive growth; cultivate the fruiting branch group to promote a large number of fruit and maintain the crown structure And the tree vigorously prolongs the fruiting life. This year, the pear trees that have been replanted with high grafting will replant the old branches, guide the extension of new branches, protect the flower buds, and create conditions for the fruit retention next year. After the pear tree enters the senescence period, the vigor of the tree gradually weakens, and the growth volume decreases year by year. The growth of the branches outside the crown is very weak, the new shoots are few, the backbone branches are bare, the results are weak, the results are poor, the yield is reduced, and the dead branches are obvious. increase. During this period, on the basis of strengthening fertilizer and water management, the main task of pruning is to renew and rejuvenate, strengthen tree vigor, and delay the senescence and death of backbone branches. In addition, Liyuan should also pay attention to clearing the garden. Repair the drainage and irrigation pump room facilities, clean up the ditch system, the horizontal ditch is 0.4 meters deep, and the waist ditch is 1 meter deep; pick up fallen fruits, remove the empty bags on the tree, and check the root tillers at any time. Pear trees with nodules should be dug out. At the same time, to do a good job of scraping and disinfection of ring streak disease, use 80% carbendazim wettable powder 100 times solution (about 30 kilograms of water + 150 grams of pesticides per barrel) to sterilize the branches.
