Description

Multifunctional girdling knife for citrus reiliana trunk

Technical Field

The utility model relates to the technical field of fruit tree pruning tools, in particular to a multifunctional girdling ring barking knife for a citrus reticulata trunk.

Background

The hybrid citrus variety is a late-maturing hybrid citrus variety, and has the characteristics of vigorous growth vigor, less fruit falling in winter, strong fruit bearing capacity and long fruit bearing and harvesting period. In order to avoid fruit being smaller and bearing fruits in different years, trees which grow over-vigorously or have less flower amount in the past year can be girdled or girdled to promote flower bud differentiation, the girdling can be carried out in the middle and late 12 months, the cortex is preferably cut off without damaging the xylem, and the girdling part is cut annularly on the main branch or the secondary branch or the local part of the branch. During the period from the flower withering to the spring tip aging of the strong vigorous tree, when the physiological fruit drop reaches the ideal fruit amount, the strong vigorous tree can be selected to girdled (girdled) on the trunk or main branch for one time on a cloudy day or a sunny day, so that the phloem is cut off, the nutrient of the photosynthesis is prevented from being transmitted to the root and being accumulated on the overground part, and the purposes of flower and fruit retention are achieved.

In the actual production, girdling or girdling needs to be selected according to the growth condition of fruit trees, and girdling knives with different specifications need to be selected. The girdling cutters or girdling cutters are designed separately, the girdling cutters of different specifications and models are also designed separately, the carrying is inconvenient, the angles of the cutters and the clamping pieces are fixed, the cutters and the clamping pieces cannot be adjusted according to the trunks in different growth periods, the operation is laborious, and the xylem of the trunk is easy to hurt.

Through retrieval, a patent document with an authorization notice number of CN211832005U discloses a multifunctional girdling ring stripping knife for a citrus reticulata trunk, which comprises a handle, a knife arm and a blade, wherein the blade comprises a girdling knife and a first ring stripping knife, the knife arm is of a sheet structure with concave arc-shaped edges at two sides, the girdling knife and the first ring stripping knife are respectively positioned at the outer end of the concave arc-shaped edge at two sides of the knife arm and at one end far away from the handle, and the cutting edges of the girdling knife and the first ring stripping knife are arranged at one end close to the handle; the handle is including first bracelet and the second bracelet of locating the arm of a knife both sides, first bracelet, second bracelet and arm of a knife pass through connecting portion and link to each other. Although the utility model discloses a make up girdling sword and ring barking sword to can change the model of ring barking sword, can adjust the required cutter that uses according to the growth vigor of mandarin orange fruit tree more, convenient operation is simple. The arc sword arm is the acute angle setting respectively with girdling sword and girdling sword, and during the operation, bracelet and blade are located the both sides of arc sword arm respectively, and the simple operation is laborsaving.

However, this scheme has designed a cutter arm and used with girdling sword or girdling sword cooperation respectively, but because the operation needs the workman to cut into the circularity with the bark around the trunk round, under the circumstances of not having instrument assistance, manual operation hardly realizes cutting the cyclization, consequently can't reach the purpose of girdling or girdling, need repair once more, has increased work load, in addition, the girdling sword and two girdling sword that this scheme designed do not protect the cutting edge although convenient to detach changes, easily accidentally injure the workman when having the place.

Therefore, there is a need to provide a new multifunctional girdling knife for a citrus trunk to solve the technical problems.
