The basic method for pruning the fruit trees is short cutting, shrinking shearing and thinning shearing, wherein a short cutting method is needed to be used to prune part of old branches of the fruit trees after the fruit trees are grown for a certain period, if weak branches, bald branches and old branches are more on the fruit trees, the branches need to be pruned by using a shrinking shearing method, and the branches of the fruit trees are too dense and need to be pruned by using a thinning shearing method.

The short cut means that after the fruit tree grows to a certain age, the fruit tree is pruned in a proper season, and part of old branches and long branches need to be pruned. When pruning, aged branches on the lateral branches can be cut off, part of old leaves are also cut off, and robust branches are reserved. The fruit tree is cut short, so that the nutrients can be saved for the fruit tree, and the fruit tree can grow better.

During the period of pruning, the method of reducing the pruning is also more used. When pruning, the weak single branch, bald branch and aged branch on the fruit tree can be pruned, which is beneficial to the growth of the fruit tree. The fruit tree can grow well and branches are robust by performing the contraction shearing work, and the quality and the quantity of the fruits can be ensured as long as the fruit tree is properly maintained in the later period.

The thinning and shearing mainly comprises the step of shearing off dense branches and overgrown branches of fruit trees. After the dense branches are cut off, the growing space of the branches is enlarged, the branches can be prevented from being heavy and crossed, and the growth of branches and leaves is facilitated. The flowers also need to be cut loose, and dense flower buds need to be cut off, so that the nutrient can be saved, and the later flowering of fruit trees is facilitated.

When pruning, notice the light transmissivity and the air permeability of whole tree vigor, for the fruit tree can many results, can leave many lateral branches or branches usually, leave too much, the fruit knot will be many, but if illumination shelters from more seriously, will lead to the fruit colour inhomogeneous, the fruit is less, the taste is relatively poor, photosynthesis is few, the sugar is low, to a great extent influence quality, consequently, combine the illumination condition, prune the branch, prevent that illumination from being sheltered from, because some branch height is higher when pruning, consequently, when adopting the trimming means of this application, notice the centre gripping to the branch, prevent that the branch from falling freely and appearing pounding operating personnel's the condition.
