Super-slender spindle-shaped dwarfing compact planting cultivation method for cherries

Abstract

The invention discloses a super-slender spindle-shaped dwarfing compact planting cultivation method for cherries. The super-slender spindle-shaped dwarfing compact planting cultivation method comprises the following steps of firstly, planting the cherries: enabling the space between plant rows to be (1.8 to 2.0)m*(4.5 to 5.5)m, and planting 67 to 75 plants of cherries in each mu; secondly, training and pruning: performing field planting in autumn of the first year but not performing stem pruning; performing field planting in the second year, and performing training and pruning using a bud picking and carving pruning technology in spring; performing field planting in the third year and the fourth year, and continuously cultivating 15 to 18 main branches by adopting the bud picking and caving mode, wherein the space between every two main branches is 20 to 30cm; performing cutting-back pruning on one-year main branches by adopting a double-bud cutting technology at the free treetop growing stage of the cherries in spring and autumn, leaving the main branches by 65 to 70cm, and pruning perennial branches by adopting a non-pruning technology; performing crown head sagging after cherry trees enter the fruit bearing stage for three years, controlling the height of the crown to be 3.5 to 4.0m, and obtaining the formed tree shape, namely a slender spindle shape. According to the super-slender spindle-shaped dwarfing compact planting cultivation method disclosed by the invention, a narrow-row-spacing and wide-line-spacing planting mode is adopted, so that the labor is saved, and the mechanical operation is facilitated; meanwhile, a training and pruning technology is easily and quickly grasped; the super-slender spindle-shaped dwarfing compact planting cultivation method has the characteristics of easiness for management, early shaping, early fruit bearing, high yielding ability and the like.

Description

technical field [0001] The invention relates to a method for dwarfing and densely planting cherries, in particular to a method for cultivating ultra-slender and spindle-shaped dwarfing and densely planting cherries. Background technique [0002] The slender spindle shape is a tree shape generally recognized by sweet cherry cultivation countries all over the world. It has the advantages of less investment in plastic surgery, faster forming, earlier high-yielding period, reasonable tree structure, good ventilation and light transmission, and large space between rows for convenience in the field. It is easy to operate and easy to update branches after entering the high-yield period. Therefore, high-density planting, dwarf cultivation, and mechanized orchard management have become the mainstream trend of fruit tree planting in the world today. At present, the planting density of cherries is low, and the degree of dwarfing is low. The cultivation and management methods of slende...

AI Technical Summary

Problems solved by technology

At present, the planting density of cherries is low, and the degree of dwarfing is low. The cultivation and management methods of slender or free-spindle shaping are adopted. Dry, low yield, usually 700-1200kg per mu in full fruit stage

For example, the prior art CN201410400049.6 discloses a planting method for cherries. The plant row spacing is 3m×4m, and the stem is fixed at about 80cm. Free spindle shaping is adopted, the cultivation management is complicated, it is not easy to quickly master, and the yield is not high.
