Description

Tree shape pruning device for pear trees

Technical Field

The utility model relates to an agricultural apparatus preparation technical field, specificly relate to a tree-like whole branch ware of pear tree.

Background

The tree form of the pear tree is an important content of pear tree cultivation, and different tree forms have great influence on the difficulty and easiness in management of the pear tree and tree vigor, yield and quality. At present, the main tree forms adopted in the pear tree production in China include sparse layered forms, spindle forms, open heart forms, shed frame type tree forms and the like. The sparse layered shape is the traditional shape of a northern pear tree, the crown of the pear tree is high and large, the skeleton is firm, the service life is long, the yield is high, the yield is stable, but the defects of inconvenient management, uneven fruit quality and the like exist. The fusiform (natural fusiform, improved fusiform and the like) has the advantages of quick forming, high yield of early fruits, easy management and the like, and is a high-yield tree form suitable for northern dense planting cultivation. The southern pear garden mostly adopts the shape of a heart (the shape of a heart with three main branches, a Y shape and the like), and has the advantages of simple tree structure, good ventilation and light transmission, good fruit quality, high commodity rate and the like.

The problem of wind damage is solved by adopting a shed frame cultivation mode in the early nineties of China, the wind resistance is enhanced by fixing branches through a shed net frame, fruit dropping and mechanical damage caused by wind damage are obviously reduced, the shed frame type tree shape is balanced, branches and leaves are uniformly distributed, the illumination is good, the fruit size is neat, and the quality is good. Due to the limitation of the height of the greenhouse, the common tree crown applied in the current production is higher, and is not suitable for being applied to greenhouse cultivation; meanwhile, the greenhouse is a relatively high-temperature, high-humidity and weak-illumination area environment, and a high-light-efficiency tree form which is suitable for greenhouse cultivation, has a dwarfed crown and is good in ventilation and light transmission needs to be developed.

However, no proper tool is available for trimming the tree shape of the pear tree, and management of the tree shape of the pear tree is inconvenient. Traditional pruning ware length range is limited when the pruning, only can press the pruning pole through the staff through two fixed pruning cylinders and carry out the branch pruning, at the pruning in-process, need personnel to push down the pruning pole hard constantly, this kind of pruning ware structure seems simple, does consume staff's physical power, extravagant pruning time, need move one side skew gradually when carrying out the pruning to the great branch of crookedness simultaneously, it is very inconvenient to operate, the pruning work efficiency is lower.

Therefore, a more convenient pear tree shape pruning device for shaping pear trees is needed to overcome the defects.
