Description

Grafting tool

Technical Field

The utility model belongs to the technical field of facility cultivation, and particularly relates to a grafting tool.

Background

The cucurbit is used as a stock for grafting, so that the capability of resisting the fusarium wilt of melons such as watermelons, melons and cucumbers can be improved, and dead seedlings caused by the fusarium wilt can be effectively prevented; can also improve the low temperature resistance of melons such as watermelon, melon, cucumber and the like. Is very practical for cultivation in protected areas in early spring and can be marketed in advance. Meanwhile, the grafted melon seedlings have developed root systems, enhanced absorption capacity and transmission capacity and high yield potential. Moreover, fertilizer can be saved through grafting, and the fertilizer absorbing capacity of grafted seedlings is enhanced compared with that of self-rooted seedlings due to strong root systems of the stocks. The top plugging method is generally adopted, so that the management is simpler and more convenient, and the survival rate is higher.

Sowing and grafting arrangement: taking watermelon grafting as an example, the cucurbit stock is sown about 7-10 days earlier than the watermelon, and the best grafting period is generally from the first true She Pingzhan to the second true bud of the stock when the cotyledon of the watermelon is straightened to open after emergence of the watermelon. The cucurbit rootstock and the watermelon are watered thoroughly the day before the seedling grafting. The operation method comprises the following steps: during grafting, the growing point of the stock seedling is firstly removed, and then the grafting needle tip is inserted downwards from the growing point part in a direction parallel to the cotyledon by about 1 cm in an inclined way by using the flat surface of the tip of the grafting needle, so that the grafting needle tip is just exposed out of the stock. And then the scion is taken, a wedge-shaped surface is cut at a position 1 cm below the cotyledon of the watermelon seedling by using a grafting knife, the length is about 1 cm, the grafting needle is pulled out, a scion incision is inserted into the hole downwards, and the tip end is exposed out of the stock. The whole manual operation process comprises 5 actions of removing the core of the stock, beveling the scion, inserting the jack of the stock, pulling out the grafting needle, inserting the scion and the like, and two tools of the grafting needle and the grafting knife are needed to be replaced alternately, namely, the grafting needle and the grafting knife are needed to be put down and lifted up continuously, so that the operation is inconvenient and the efficiency is low.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

As shown in fig. 1 to 3, the grafting tool of the present utility model comprises a needle body 1, a connecting rod 2, a blade 3 and a finger stall 4. The needle body 1 is fixedly connected with one end of the connecting rod 2, the blade 3 is sleeved at the other end of the connecting rod 2, and the fingerstall 4 is in threaded connection with the side surface of the middle part of the connecting rod 2. The connection mode of the needle body 1 and the connecting rod 2 can be integrated, or other connection modes can be adopted, such as welding, bonding, inserting, clamping, threaded connection and the like.

The needle body 1 is arranged into a nested structure and comprises an inner needle 5 and an outer needle 6, the outer contours of the inner needle 5 and the outer needle 6 are basically the same, the outer contours of the inner needle 5 and the outer needle 6 both comprise a needle point and a needle rod, the needle rod is of a cylindrical structure, and the needle point is of a cylindrical chamfer. The inner needle 5 comprises an inner needle tip 11 and an inner needle shaft 12, and the outer needle 6 comprises an outer needle tip 13 and an outer needle shaft 14. The difference is that the diameter of the outer needle 6 is larger than that of the inner needle 5, the outer needle 6 is of a hollow structure, the inner needle 5 is of a solid structure, the inner diameter of the outer needle 6 is larger than the outer diameter of the inner needle 5, and the outer needle 6 is closely sleeved on the outer periphery of the inner needle 5 in a matching way.
