Pruning method for peach trees

Abstract

The invention provides a pruning method for peach trees. The method comprises the following steps: rapidly fixing trunks after the peach trees are colonized, and simultaneously removing all branches on the trunks, wherein the trunks are 50 to 60cm high; pruning peach tree seedlings twice in the first year, rapidly culturing the trunks to form peach tree plants of which the trunks play a dominant role, and forming 0.60 to 2.5m three-dimensional fruiting intervals under the assistance of corresponding fruiting branches to simplify the shapes of the trees into shapes formed by the trunks and the fruiting branches to rapidly achieve fruiting capability; pruning the trees in two rounds every year by removing the fruiting branches in every summer and removing large branches and thinning fruit branches in every winter to keep the shapes of the trees substantially unchanged and keep the fruiting capability of each peach tree substantially unchanged from the second year. According to the method, the shapes of the trees are simplified into the shapes formed by the trunks and the fruiting branches to rapidly achieve the fruiting capability, and meanwhile, planar fruiting branch layers of conventional tree shapes are replaced by three-dimensional fruiting branch layers to utilize the perpendicular space, so that the growth space of the fruiting layers is enlarged, and the coloring and fruit quality are improved.

Description

technical field [0001] The invention relates to a pruning technique for fruit trees, in particular to a pruning method for peach trees. Background technique [0002] In terms of the planting mode of peach trees, at present, most of them advocate the sparse planting of large trees, and the planting density is mostly 3*4m, 4*4m, 5*4m, or even 6*5m, etc. The tree shape trimming generally pays attention to three strands, six forks and twelve branches , by pulling branches and pruning, the fruiting branches are basically stabilized on a plane, which is convenient for picking, ventilation and sunlight. However, due to the limitation of the field space, the fruit yield per mu is limited. Most of the peach orchards that have entered the high yield period have only 2000 to 3000 catties. [0003] In the pruning method, the pruning method of "trunk + production trunk + fruiting branch group + fruiting branch" is adopted, and short pruning is mainly used. After several years of pruning, ...

Problems solved by technology

This is the reason why many peach orchards lose their economic value as soon as they enter the high-yield period, resulting in a decrease in the overall economic value of investment in Tao orchards, failing to achieve theoretical benefits

[0005] Under the current planting and pruning mode, after several years of growth, the branches of peach trees basically cover all the space in the peach orchard. In summer, there is no ventilation and it is not convenient to work, which is easy to breed diseases and increase management costs.
