The methods of pruning branches of fruit trees include pruning sequence, pruning thick branches and sawing big branches, as follows:

1, pruning order

Trim the upper part of the crown first, and then trim the lower part of the crown; Prune the main branches and leaves first, and then prune other branches; Trim from the inside of the crown first, and then trim the outside of the crown; Comb the big branches first, and then comb the small branches.

Step 2 prune thick branches

Hold the scissors in one hand and push the branch to the scissors mouth with the other hand. Two hands cooperate with each other to cut off the thick branches. When trimming, be careful not to shake the scissors left and right to avoid blade deformation.

3. Saw off the big branches

We should start from the bottom of the fruit tree, saw some shallow cuts from bottom to top, and then saw off the big branches from top to bottom, so as to ensure that there are no residual piles and prevent the branches from splitting and hitting other branches. In addition, it is necessary to ensure that the incision area is small, the wound should be flat with the mother branch, and the lower part should be prominent for easy combination.

Winter maintenance of fruit trees

Plastic pruning, through plastic pruning, cultivate a reasonable tree shape, cut off unnecessary branches, promote the growth and fruiting of fruit trees, and achieve the purpose of early formation, early fruiting and high and stable yield. Cleaning the orchard, combined with pruning in winter, can completely remove insect branches, diseased branches, dead branches, fallen leaves, weeds and rotten fruits of fruit trees, take them out of the orchard for burning, eliminate many overwintering germs and pests, and reduce the occurrence of fruit tree diseases and insect pests in the coming year.

For orchards with deep tillage and shallow soil layers, the orchards that bear fruit at the beginning of 2-3 years after planting should be ploughed and expanded to a depth of 50-60 cm to improve the growth conditions of roots; The orchard with thick soil layer can be turned to a depth of 30 cm, which changes the overwintering environmental conditions of pests, makes them freeze to death or die because they cannot be unearthed, and achieves the effect of loosening the soil to kill pests. Pest control, winter fruit tree diseases and insect pests enter dormant period, and timely control of pests and diseases can greatly reduce the occurrence of pests and diseases in the fruit tree growing season in the coming year.
