When applying base fertilizer, it should be combined with the work of deep turning and hole expansion. Mainly rotten farm manure, the amount of each pear tree is kept at about 60-80kg, combined with an appropriate amount of compound fertilizer, watering and covering soil after application. Then we should trim the roots and cut the roots, and the depth of the fertilizer ditch should be about 10cm, so as to ensure the balanced growth of the pear tree.

2. Pulling branches and hanging branches

When we manage pear trees in autumn, we should also do a good job of pulling branches and hanging branches. Branch pulling can make young trees form crown earlier, make pear trees shoot earlier and increase shoot quantity, so as to prevent pear trees from over-vegetative growth. Generally speaking, it should be carried out after the defoliation of pear trees in autumn. for 2-3-year-old pear trees, the main branches, extended branches and secondary main branches should be the main branches. The main object of the hanging branch is the following hanging branches, because if the drooping branches bear too much fruit, it is easy to split, so we can tie up the long rafters on the middle trunk, and then tie the fruit branches of the pear tree to the rafters.

The time of pear leaves falling is relatively early, in October, it is easy to appear the phenomenon of Xiaoyang spring. Therefore, pear trees generally blossom in autumn, thus affecting the yield of the following year. The main reason for pear trees to blossom in autumn is due to diseases and insect pests such as scab and pear planthopper.
