Peach tree shaping and trimming method

Abstract

The invention discloses a peach tree shaping and trimming method. The peach tree shaping and trimming method specifically includes the step of cultivating a peach tree for three years to four years to form a tree of an open centre model, wherein the tree of the open centre model is composed of a layer of main branches including three to four main branches on the base part and a central trunk, the peach tree is basically made to be in a free state in the first year after being planted, no trimming or branch pulling is conducted, the adjusting capacity of the peach tree itself is fully utilized, and the tree in the open state, namely, the tree of the open centre model, is naturally formed. The peach tree shaping and trimming method is characterized in that except that extending branches at the top ends of the main branches and excessively-weak fruited branch groups are cut back and retracted, the rest of branches are trimmed mainly. No side branches are arranged on the main branches any more, and large-sized, medium-sized and small-sized fruited branch groups are directly arranged on the left sides and the right sides of the main branches. The peach tree provided through the method can be efficiently and easily shaped and trimmed in a labor-saving and standardized mode, the framework is clear, operation is easy, the upper branches of the tree formed through the method cause less influences on the lower branches, ventilating and light transmitting conditions are good, and early bearing and high yield can be achieved.

Description

Technical field [0001] The invention relates to a method for shaping and pruning fruit trees, in particular to a method for shaping and pruning peach trees. Background technique [0002] Peach trees are light-loving species. The shape and structure of the peach tree directly affect the distribution of light in the crown, photosynthetic productivity, flower bud formation, flower bud quality and branch life, and further affect the yield and quality of the fruit. The tree shapes currently used in the country include the conventional open-hearted tree shape with a large canopy, the natural spindle shape that can be cultivated densely, and the main trunk shape such as modified spindle shape. The conventional open-hearted tree shape has low yield and slow formation in the early stage. From the full fruit stage, due to the large amount of nutrients flowing to the top of the canopy and the fruit, the base of the tree body cannot be fed by the leaves for a long time, the main stem senesce...
