How to maintain fruit tree lopping shears?

Before winter pruning fruit trees, a reasonable pruning plan should be determined according to the variety, age, density, body structure, growth potential and fruit volume of the fruit trees.

1. Electric fruit tree lopping shears - pruning backbone branches
Pruning starts with the main branch at the base, and cuts from the full bud, but pay attention to the orientation of the cut. Auxiliary branches should be kept between the side branches according to the spatial orientation, and the upright branches, leggy branches and competing branches on the back should be thinned out. After pruning, another main branch should be pruned.

2.Pruning auxiliary branches
The shape of fruit trees is mostly layered. After cutting the main branch at the base, prune the auxiliary branches between the layers. Auxiliary branches can be inserted to fill the gaps, and there is no space for retraction or thinning. If the side branches of the tree have large space, the auxiliary branches can develop into a fan shape.

3. Review pruning
Fruit trees should be carefully inspected after pruning. After the fruit tree is pruned, the tree shape requires that the branches do not overlap up and down, the neighbors do not cross left and right, and the flower buds and leaf buds are evenly distributed.
