Sweet cherry high spindle shape and training and pruning method of sweet cherry

Abstract

The invention relates to a sweet cherry high spindle shape and a training and pruning method of a sweet cherry. The standardized parameters of tree framework of the sweet cherry high spindle shape are as follows: the height of tree is 2.8 to 3.0m; the height of trunk is 0.65 to 0.75m; the number of skeleton branches is 35 to 40; the angle of each skeleton branch is larger than 90 degrees; the space between every two skeleton branches is 5 to 7cm; the length of each skeleton branch is less than 1.5m; the diameter of each skeleton branch is less than 4cm; the quantity of branches per mu is 27500 to 28500; the ratio of a long branch to a medium branch to a short branch is 2 to 1 to 8. The training and pruning method comprises the four steps of culturing a strong and vigorous central leader branch, promoting the central leader branch to germinate more lateral branches in a dropping state, and promoting the lateral branches to generate buds; enabling the central leader branch to continuously sprout lateral branches, and controlling the height of tree; controlling the buds on the back of the lateral branches; controlling lateral generation. According to the sweet cherry high spindle shape provided by the invention, seedlings are planted and high-yield tree shapes are built within three years, the branch distribution is reasonable, the density is moderate, ventilation and transmittance among rows of tree are good. Early-fruiting and high-yield are realized.

Description

technical field [0001] The invention relates to a fruit tree shape and its shaping and pruning method, in particular to a sweet cherry tall spindle shape and its shaping and pruning method. Background technique [0002] Since the introduction of large cherry in my country in 1871, it has been cultivated for more than 140 years. Big cherry is one of the tree species with the largest growth in deciduous fruit trees. It has strong tree vigor, vigorous growth, strong germination ability, weak branch formation ability, and is extremely sensitive to pruning. Under natural conditions, the tree body grows vigorously, the branch angle is small, it is difficult to form flowers, the result is late, the yield is low, and the tree body is tall and difficult to pick. [0003] The pruning of sweet cherries is a guarantee of high quality and high yield. There are also many problems in the shaping and pruning of sweet cherry in production, as the sweet cherry seedlings grafted with arboriz...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a high-spindle shaping and pruning method for the production of sweet cherries, so that the sweet cherry trees can be quickly formed after planting, and can bear fruit early and yield early, and solve the disorder of cherry tree shape and tree shape cultivation time in the production of sweet cherry in the prior art. Long, late fruiting, low yield, and the handover between rows of crowns causes difficulties in daily management
