The branches of autumn pear trees are mostly used for young trees of 1-3 years old. Every year after the pear leaves fall, it is a technical job to pull out the branches. It's no use pulling the branches too lightly. After a long time, these branches will continue to grow upwards. If you pull the branches hard, several branches in the small pear tree will break. Therefore, pruning is generally gradual and cyclical.

Management methods of pear trees in autumn;
1, soil management
Adopting the method of planting grass and covering, interplanting clover and alfalfa between rows through the growth and covering of grass. When the green manure crop grows to 30~40cm, it is mowed 2~4 times a year, and the height of each crop is 10cm. Covering the cut grass on the tree tray can improve the physical and chemical properties of soil, adjust the microclimate environment in the field and play a role in soil and water conservation.
2. Fertilization management
Fertilization in autumn is mainly based on organic fertilizer, supplemented by balanced compound fertilizer, medium and trace element fertilizer and living soil biological bacteria fertilizer. Three times a year, accelerating germination fertilizer, mainly nitrogen fertilizer, combined with spraying hail biological stimulator; Fertilization after flowering, mainly nitrogen and phosphorus, combined with trace elements such as boron, magnesium and zinc, and spraying the leaf shape of sea elf biostimulant can improve the seed setting rate; The fruit puffing fertilizer mainly includes phosphorus, potassium and calcium, which is combined with red pond foliar fertilizer to improve fruit quality. Applying foliar fertilizer in the later stage can increase chlorophyll content, promote flower bud differentiation, delay leaf senescence and delay defoliation time.
3. Water management
Water in time after fertilization. According to the soil moisture content, determine the appropriate irrigation time and frequency, and drain the accumulated water in time in case of heavy rain.
