Abstract

The present invention relates to a cucurbit double grafting method, utilizing a hypocotyl or a stem of a definite bud or a leaf of a to-be-harvested cucurbit as a scion to be cooperatively grafted to lower hypocotyls of two excellently compatible cucurbits that are served as stocks. The grafting method sequentially comprises the following steps: a stock plantation step, providing two cucurbits served as proximal stocks for plantation; a scion-acquiring step, acquiring the hypocotyl or the stem of the definite bud or the leaf of the to-be-harvested cucurbit as the scion; a stock-connecting operation, correspondingly destroying the lower hypocotyls of the two stocks so that the lower hypocotyls of the stocks are correspondingly formed with individual granting sites; a scion-cutting step, cutting the hypocotyl or the stem which is located below the definite bud or leaf of the scion into halves so that the hypocotyl or the stem is formed with two grafting parts with cutting surface respectively; and a grafting step, respectively placing the two grafting parts at the grafting sites of the lower hypocotyls of the two stocks, enabling the grafting sites of the lower hypocotyls of the two stocks and the cutting surfaces of the grafting parts of the scions to be mutually approached and attached, and externally fastening the lower hypocotyls of the two stocks and the scions. Accordingly, a grafting process is completed.

Description

Cucumber double grafting method

The invention relates to a method for grafting melons, in particular to a double grafting method for melons.

According to the early cultivation of melons such as watermelon, the seeds were directly planted. Later, due to changes in climate and environment, the disease was becoming more and more serious, resulting in a poor harvest of watermelons and even no loss of blood. Therefore, grafting was used to plant and draw similar melons. As a rootstock and with strong antiviral ability at the root, and the advantages of wild development, to resist the occurrence of vine disease and root nodule nematode disease, and increase cold resistance, improve early maturity, improve moisture resistance, preserve various melons The original flavor and quality are used to increase the yield, improve the quality and increase the profit. The grafting method of the known melons has the following steps, and also refers to Figure 5: Rootstock cultivation: strong resistance in the seedling tray The melons (such as: pumpkin, loofah, etc.) as the first rootstock (30), to grow the hypocotyl; to obtain the scion: the melons (such as: watermelon, bitter gourd, etc.) with poor resistance to the harvest, Take the shoot bud as the scion (40); the first graft: cut the hypocotyl of the first rootstock (30) longitudinally into the cut (301) with the flat cut surface in the nursery tray, and the bottom end of the scion (40) Corresponding slit (301) cut out flat a cut surface (41) for inserting the cut surface (41) of the bottom end of the scion (40) into the slit (301) of the first rootstock (30), and then cutting the cut (301) of the first rootstock (30) with the scion (40) The cut surface (41) is fixed at the joint, and after the graft is completely healed, it is planted in the field, that is, the first graft is completed (as shown in Figures 6 and 7); The second grafting: the second rootstock (31) is planted around the grafted seedlings that have been grafted for the first time. When the second rootstock (31) grows to at least ten leaves, it is cut through the side of the scion (40). Grafting the hole (42), and cutting the top end of the second rootstock (31) corresponding to the grafting hole (42) of the scion (40) into a flat cut surface (311) to insert the cut surface (311) of the second rootstock (31) In the grafting hole (42) of the attachment ear (40), the joint of the grafting hole (42) of the scion (40) and the cutting surface (311) of the second rootstock (31) is fixed, and the second grafting can be completed ( Please also refer to the schematic diagram of the existing graft completion status in Figure 7.

It is not difficult to find out the shortcomings of the above-mentioned conventional structure. The main reasons are as follows:

(1) The grafting method of the conventional knowledge is that it takes at least ten days for the rootstock (30) and the scion (40) to completely heal from the graft to the wound, the vascular bundle can be completely connected, the water and nutrients can be transported, and the grafted seedlings can continue. Growth, and because the scion is too short after the first grafting, there is no place for grafting, and the length of the rootstock is too short, so the conventional double grafting method must first plant the field and wait for it to grow to the appropriate length after the first grafting. Grafting, but it takes more than ten days to waste, and the second grafting method of the traditional double grafting method needs to be grafted in the field, so that the joint of grafting is easily affected by external factors such as rain pollution and strong wind pulling. The grafted joints cannot be tightly joined, which seriously affects the survival rate of grafted seedlings.

(2) It is also known that the grafting method can only form a hypocotyl or a stem at the scion (40) at each cutting. To graft two rootstocks, it must be at least twice the hypocotyl of the scion (40) or Cutting the stem and increasing the number of cuttings of the scion (40) not only wastes time, but also increases the risk of failure of the cutting scion, and some scion (40) hypocotyls or stems are very thin, when cutting the scion (40) using conventional grafting methods, Not only difficult to cut, but also It is easy to cut the scion (40) hypocotyl or stem too thin or to cut, so that the graft survival rate is seriously reduced.

In view of this, the inventors have been engaged in the manufacture, development and design of related products for many years, and have made the invention effective in view of the above-mentioned target inspection, detailed design and prudent evaluation.

(1) According to the grafting method, it takes at least ten days for the rootstock and the scion to completely heal from the graft to the wound. The vascular bundle can be completely connected, the water and nutrients can be transported, and the grafted seedlings can continue to grow, and After the first grafting, the scion is too short to be grafted, and the length of the rootstock is too short. Therefore, the conventional double grafting method must first plant the field after the first grafting, and then grow it to the appropriate length for grafting. It takes more than ten days to waste, and the second grafting method of the conventional double grafting method needs to be grafted in the field, so that the joint of grafting is easily affected by external factors such as rain pollution and strong wind pulling, resulting in the grafting joint. The situation cannot be closely combined, which seriously affects the survival rate of grafted seedlings.

(2) It is also known that the grafting method can only make the hypocotyl or stem form a cut surface. To graft two rootstocks, it is necessary to cut the hypocotyl or stem at least twice, and it is not only a waste of time to increase the number of scion cutting. At the same time, it also increases the risk of failure of cutting scion, and some of the scion spindles or stems are very thin. When cutting the scion using the conventional grafting method, not only the cutting is difficult, but also the scion or stem is too thin or cut. Therefore, the graft survival rate is seriously reduced, and the above is the technology to be solved by the present invention. The problem is the point.

The melons; the scion: the melons to be obtained, the hypocotyls or stems containing at least a certain bud or a leaf as the scion; the rootstocks are connected: the two rootstock hypocotyls are correspondingly destroyed and processed, so that The hypocotyls of the rootstock are correspondingly formed with a grafting place, wherein the grafting portion can be formed by chamfering to form all the faces, or a perforation is formed by acupuncture; the cutting of the scion: cutting the scion or the hypocotyl or stem under the blade into two Half, the hypocotyls or stems are respectively formed into two-grafted sections; grafting: the grafting parts of the scion are placed in the grafting of the hypocotyls of the two rootstocks, and the grafting of the grafts of the two rootstock hypocotyls with the scion unit Bonding surfaces close to each other, and then the hypocotyl by the outer two rootstock scion be fixed together, to complete the grafting procedure.

(1) The grafting method of the present invention cuts the two ends of the hypocotyl or stem of the scion into two grafting parts, and then respectively fixes and fixes the grafting parts of the two grafting parts and the two rootstocks respectively. The scion and the second rootstock can achieve the double grafting effect in a single process, shorten the time for the rootstock wound to heal, and prevent the wound from being affected by external factors such as rainwater pollution or strong wind pulling, thereby accelerating the efficiency of the nutrient absorption of the scion and continuing. Growing up.

(2) The two grafted parts of the scion are evenly distributed with an equal amount of absorption area combined with the rootstock, and can effectively prevent the scion from forming too thin or having a cut in the cutting process, and adding the scion to the graft The success rate of the rootstock and the better survival rate.
