Description

A young branch growth auxiliary device for fruit tree grafting

Technical Field

The utility model belongs to the technical field of the fruit tree grafting, especially, a twig growth auxiliary device for fruit tree grafting.

Background

The fruit tree grafting is to take the branch or bud of the excellent variety plant to be grafted to the proper position of another plant, combine the two to generate a new plant, the grafted branch or bud is called as the scion or the scion bud, and the plant connected with the scion or the scion bud is called as the stock. The new plant obtained by grafting propagation can maintain the excellent characteristics of the stock plant, and has the excellent characteristics of the stress resistance, adaptability, early bearing property and the like of the stock, so that the fruit tree grafting has good effects on seedling breeding and variety improvement. The correct grafting and maintenance of the fruit trees are the main factors for determining the survival of the grafting. The survival and growth situation of the grafted young branches are the key for determining the success or failure of grafting, the grafted young branches are maintained, the young branches are prevented from being broken due to high wind and heavy rain in the growth process, the lateral or downward growth of the young branches caused by the grafting position and subsequent growth is corrected, and the method has important significance for promoting the formation of fruit trees as soon as possible, the high yield of early fruits and the quality and efficiency improvement.

The traditional young branch maintenance method is to fix a wooden stick or crop straws on a stock, wind the wooden stick and the young branches by ropes, and cut off a binder during grafting after fixing the young branches. However, the method is easy to cause the abrasion of the trunk and damage the epidermis of the trunk when being bundled; still some fruit growers use iron wires and thin ropes as branch fixing tools, and tie the branch in the middle of the branch directly, so that the iron wires and the thin ropes sink into the cortex of the branch to cause the damage of the young branch, which is not beneficial to the blooming and the fruit bearing of the fruit tree.

Some devices for assisting the positioning are used to fix the grafted plant, but these devices still have certain disadvantages: as disclosed in publication nos.: a patent document CN113748921A discloses a supporting auxiliary device for fruit tree grafting, which is used for fixing and supporting a grafting position, but the device can only perform binding and positioning at the joint of a stock and a twig, and cannot limit branches of the twig, and in the subsequent growth process, the branches easily grow transversely or downwards, which is not beneficial to the grafting forming of plants;

the publication number is: CN216452032U discloses a seedling fixing device for grafting, which can perform directional restriction on young branches while fixedly supporting the grafting position, but the device has certain limitations in practical use: on one hand, the grafting position is fixed by the arc-shaped plate, but the same arc-shaped plate cannot adapt to stocks with different thicknesses, and the customized production is required according to the thicknesses of the stocks in use, so that the cost is high, the process is troublesome, the period is long, and the large-scale grafting operation is not facilitated; on the other hand, the device limits the growth direction of the young branches through the elastic band and the hook, the disassembly and the assembly between the elastic band and the arc-shaped plate are troublesome, and the use is not flexible enough; on one hand, during grafting, the longer arc-shaped plate can be sleeved on the stock, and the young branches at the sleeved position of the stock can be damaged.

Detailed Description

The utility model is described in detail with the accompanying drawings as follows:

as shown in fig. 1 and fig. 2, the utility model provides a young branch growth auxiliary device for fruit tree grafting, including position sleeve 1 and orientation mechanism, the whole injection moulding of position sleeve 1 to, seted up bell mouth 2 in the position sleeve 1, it is preferred, the bell mouth tapering is 1:0.8, in some examples, the conical hole 2 is a blind hole, and when the positioning sleeve 1 is directly sleeved on the stock during grafting, the inner hole wall or the top end of the conical hole 2 can be in a stable position after contacting the stock, and the positioning sleeve is tightly sleeved on the stock;

in some examples, a damping pad can be attached to the hole wall of the conical hole 2 to avoid slipping, so that stable installation of the positioning sleeve 1 is guaranteed, and meanwhile, in other examples, absorbent cotton can be attached to the hole wall of the conical hole 2 to guarantee stable sleeving, store moisture, moisturize the grafting position and promote plant growth;

orientation mechanism includes a plurality of adjustable pull rods, and adjustable pull rod hook is connected on position sleeve 1 and can be connected with long scion or scion bud, can carry out directional restriction to the growing direction of sprint, avoids the sprint horizontal or the situation of growing downwards to appear, promotes the grafting plant and stablizes the growth shaping to the connected mode of hook is more nimble, the dismouting of being convenient for.

Specifically, as shown in fig. 3, the adjustable pull rod includes little couple 3, two-way nut 5 and big couple 4, ring channel 6 has been seted up to the side facade of position sleeve 1, connect in the ring channel 6 and be equipped with a plurality of cylinders 7, little couple 3 hooks on cylinder 7, big couple 4 then hooks on the sprig, little couple 3, big couple 4 retractable is connected in two-way nut 5 both ends, can adjust the distance between sprig and the position sleeve 1 as required, the method is to little couple 3 and big couple 4 for two-way nut 5 adjustment that stretches out and draws back, and, little couple 3 hooks means can adjust the angle of adjustable pull rod for position sleeve 1 to a certain extent on the connected mode on cylinder 7, make its use nimble, more can adapt to various positions, the sprig of angle.

The utility model discloses a, concretely, left-handed thread groove 8 and dextrorotation thread groove 9 have been seted up respectively to the both ends of two-way nut 5, be equipped with left-handed screw thread 10 on little couple 3, be equipped with right-handed screw thread 11 on big couple 4, little couple 3 is through in the levorotation thread groove 8 of levorotation 10 cartridge on two-way nut 5, big couple 4 is through in the dextrorotation thread groove 9 of dextrorotation 11 cartridge on two-way nut 5, when connecting adjustable pull rod on position sleeve 1 and twig, little couple 3, big couple 4 all is unable wide-angle free rotation, the rotatable two-way nut 5 of user this moment, and then drive little couple 3 simultaneously, big couple 4 is perhaps reverse motion in opposite directions, and then adjust the distance between twig and the stock, thereby fixed twig direction of growth.

Specifically, in the utility model discloses in, the opening 12 has been seted up on the lateral wall of position sleeve 1. When the grafting, the twig is irregular distribution on the stock, although the top at the stock is overlapped to position sleeve 1, but also have the twig grafting in the stock top, suit position sleeve 1 will receive the twig to interfere this moment, damage the twig easily, therefore, opening 12 has been seted up on position sleeve 1's lateral wall, make the twig that is located the stock top can wear out from opening 12, avoid interfering with position sleeve 1 production, and simultaneously, in some examples, bell mouth 2 also selects for the through-hole, run through whole position sleeve 1, when sleeving 1 the position sleeve on the stock, can make even if the twig that is on the stock top surface wear out from the top of bell mouth.
