How to graft cucumber seedlings? The latest technical method tutorial

In our daily life, cucumber is generally grown from seed, and the grafting technique for cucumber is actually not well understood. The advantages of cucumber grafting are numerous; generally speaking, it can overcome the harm of continuous cropping, improve resistance, enhance quality, increase yield, and so on. So how do you graft cucumber? Today, let's learn the grafting technique for cucumber seedlings together with the editor.

1. Grafting preparation

For grafting cucumber seedlings, we need to prepare the rootstock for grafting; usually Yunnan black-seed pumpkin and white-seed pumpkin can be used. Next is to prepare the scion; the scion is the cucumber seedling. Soak the seeds to promote germination, and sow after they sprout; the rootstock also needs to be soaked to promote germination before sowing. When sowing, the times should be staggered; generally, sow the cucumber first, then after a few years sow the pumpkin seedlings, and graft when the cucumber seedlings have grown for about eight to ten days. Finally, the grafting tools also need to be prepared, such as blades, bamboo skewers, grafting clips, adhesive tape, plastic film strips, etc.

2. Grafting methods

The most commonly used methods for grafting cucumber seedlings are four: the insertion method, the approach method, the cleft method, and the splice method. Here we mainly discuss the first two grafting methods. The insertion method is divided into the diagonal insertion method and the straight insertion method. In the diagonal insertion method, the cucumber seedling is cut into a slanted surface, then inserted at a 35-degree angle to a depth of 5 mm and fixed with a bamboo skewer. In the straight insertion method, the scion is inserted directly 5 mm deep, with the rootstock and scion forming a cross shape, and then sprayed with clean water. Next is the approach method; we need to treat both the rootstock and the scion, grasp the depth of the cuts well, then insert the tongue-shaped wedge of the scion into the cut of the rootstock, and finally fix it with a grafting clip.

After grafting, we should pay attention to moisture retention. Move the grafted seedlings into nutrient pots, spray water, and build a plastic arched shed to retain moisture. After three to four days, the humidity needs to be reduced, and ventilation increased. At the same time, as time passes and the grafted seedlings grow, it is enough to maintain reasonable natural growing humidity. Next is temperature control and shading. The growing temperature should generally be kept at around 25 to 30 degrees, with the lowest temperature not below 15 degrees, and the highest temperature not above 30 degrees. At the beginning, the light exposure should not be too great, and the light intensity needs to be gradually increased with later growth. Finally, the axillary buds that were not removed during grafting should be completely cleared, and root cutting should be carried out. After root cutting, that is, the grafting of the grafted seedlings is complete, and they can be moved to the field for normal growth.

4. Precautions

When grafting, we mainly need to pay attention to these points. First is the choice of grafting rootstock; choose a rootstock suitable for local grafting. Second, the nutrient soil in the grafting seedbed should be prepared in a reasonable ratio, and the seedbed should be watered before grafting. Also, the grafted cucumber seedlings should be moved into nutrient pots, and an arched shed should be built. Finally, the grafting tools need to be disinfected.

The above is the grafting technique for cucumber seedlings that the editor has brought to you. In fact, when growing cucumbers, we are still used to seed propagation, which is simpler and not so complicated. But if you want high yield and high quality, and for the soil's use value to be further developed, then grafted seedlings are a good choice.
