The tool is low in cost and easy to use, and should be popularized and applied in the production of grafted vegetable seedlings.

Description

A vegetable grafting tool

Technical field

The utility model belongs to the field of horticultural vegetable production tools, in particular to a grafting tool for vegetable grafting and seedling cultivation.

Background technique

Watermelons, melons, cucumbers, tomatoes, eggplants and other melons and solanaceous vegetables are often harmed by soil-borne diseases and insect pests such as fusarium wilt, bacterial wilt, root-knot nematodes, and continuous cropping obstacles such as soil return to salt after long-term continuous planting. Cause plant growth and yield and quality to be seriously affected. Using rootstocks with high root disease resistance or high salt tolerance and scions of high-quality varieties to cultivate grafted seedlings is an effective method to solve vegetable root diseases and continuous cropping obstacles. There are many grafting methods, among which the plugging method is more common in the application and research of vegetable grafting. The operation process of the insertion method includes: cutting the lower end of the scion obliquely into a cone shape, removing the growth point of the rootstock, and inserting a insertion hole with a diameter slightly larger than the scion on the grafting site (the hypocotyl or the top of the stem) , and then insert the cut scion seedlings into the socket holes of the rootstock. During normal processing, the scion is first cut with a razor blade, and the rootstock growth point is removed, and then the conical bamboo stick is inserted into the socket hole. In this process, on the one hand, the razor blade and the bamboo stick are two separate tools. During operation, the razor blade or the bamboo stick need to be picked up and put down several times respectively, and the tools are frequently exchanged, which adds a number of ineffective Auxiliary operation steps; on the other hand, the edge of the razor blade is a plane, and the growth point of the rootstock cannot be removed according to the curvature of the grafting site of various vegetable seedlings, resulting in that the base of the scion after insertion is not tightly combined with the top of the rootstock jack. Affect the survival rate; at the same time, the flat blade is easy to injure the adjacent cotyledon or blade when cutting the growth point; or due to improper control of cutting force, the hypocotyl or stem of the rootstock seedling is cut off, resulting in graft failure; in addition, due to the razor blade It is very thin, and if you hold the blade directly with your fingers, it is easy to get tired after a long time of operation, which also affects the speed and quality of grafting.

Contents of Invention

The purpose of this utility model is to provide a new type of combined multi-functional tool capable of cutting scion and rootstock when vegetable grafting and raising seedlings, in order to improve grafting cutting quality and work efficiency.

The utility model purpose is achieved through the following technical solutions:

A vegetable grafting tool, including a handle and a double-sided blade, a cone and a slightly shorter handle are arranged at one end of the handle, a tongue-shaped curved knife is fixed at the top of the handle; a fixed double-sided blade is arranged at the other end of the handle The knife holder and the U-shaped bayonet; one side of the knife holder is provided with two convex posts that match the round holes of the double-sided blade, and the two outer sides of the base of the two convex posts are provided with concave holes that match the U-shaped bayonet. groove.

As a further improvement of the utility model, a protective sleeve is provided at the end where the handle is provided with the insert cone, the handle and the tongue-shaped curved knife.

During the grafting operation of the utility model, first use the tongue-shaped curved surface knife at one end to cut off the growth point on the top of the stock, and then use the inserting cone to directly insert a jack at the base of the cut-off growth point for standby; The double-sided blade at the other end cuts obliquely at the suitable part of the scion; then inserts the scion into the socket of the rootstock to complete the splicing.

The beneficial effects of the utility model are as follows: one is to combine the tongue-shaped curved surface knife for cutting off the growth point of the rootstock and the inserting cone inserted into the grafting hole on one end of the handle, and fix the double-sided blade for cutting the scion on the other end of the handle, hold The operator of the handle only needs to turn the angle of the wrist to complete the three tasks of cutting the scion, removing the growth point and inserting the grafting hole. rootstock hypocotyl or the top of the stem), it is not easy to damage the adjacent cotyledon and other parts, and it is more closely combined with the base of the scion after grafting, which is conducive to improving the survival rate of grafting; the third is that the tools do not need to be separated during the entire grafting operation process. Hands, operation steps are reduced, the grafting speed is faster, and it is less labor-saving, and the fingers are not easy to fatigue.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Example 1:

As shown in Figure 1, the component handle 1, inserting cone 2, handle 3, knife holder 6 and the protrusions 7 with grooves on the two outer sides of the base are combined to form a whole mold, which is made of ABS plastic in one injection; the protective sleeve 5 can be made of plastic injection; the tongue-shaped curved surface knife 4 has a tongue-shaped blade when viewed from above, and a semi-circular curved surface when viewed from the front. The U-shaped bayonet pin 8 can be stamped from a thin stainless steel plate; the double-sided blade 8 can be a commercially available double-sided blade.

When the vegetable grafting tool is assembled, the base ring sleeve of the tongue-shaped curved surface knife 4 is inserted and fixed on the front end of the handle 3, and then the double-sided blade 8 is installed on the knife holder 6, so that the two convex posts 7 extend from the round hole. out, and push the U-shaped bayonet pin 9 along the groove provided at the base of the boss 7, and press the double-sided blade 8 tightly, then it can be used. After use, the double-sided blade 8 is unloaded, and the protective cover 5 is inserted into the handle 1 to be provided with an end of the inserting cone 2 and the like.
