Introduction to the main techniques of grafted cucumber seedlings

Cucumber is one of the summer vegetables that are often eaten in daily life. It tastes refreshing and crisp. It is cultivated in many places in our country. There are many varieties of cucumber, often eating cucumber has a certain heat-clearing and detoxification, diuretic effect. Now there are cucumbers to eat all the year round, because of the development of greenhouse technology, the temperature has been controlled to a certain extent. In order to improve the yield and quality of cucumber, grafting is often used. Let's take a look at the main technical points of grafted cucumber seedlings.

1. Make preparations before grafting

Cucumber must be grafted before the rootstock, the second is to prepare the scion, soaking seeds to accelerate germination can be sowed. Of course, rootstocks also need to go through this step before sowing. Do not sow at the same time, first plant cucumbers, and then plant rootstocks. The cucumber can be grafted about ten days after emergence.

In addition to this, but also to prepare the relevant grafting tools, such as bamboo sticks, knives, grafting clips, stickers and so on.

2. Master the correct grafting method.

The commonly used grafting methods of cucumber are relying on grafting, splicing, inserting and splitting. The specific method is determined according to the specific planting situation.

Like the plug-in method, the cucumber seedlings are generally cut out of a bevel, and then a 35-degree angle is inserted into the 5mm and fixed with a prepared bamboo stick.

In the direct insertion method, the prepared scion is inserted directly into the 5mm, then the forehead shape of a cross is shown with the rootstock, and then water is sprayed.

If you rely on the grafting method, you need to deal with rootstocks and scions, which is more troublesome, so you must master the depth of the incision and fix it with a grafting clip.

3. Management after grafting

Attention should be paid to the moisturizing work of cucumber seedlings after grafting. It is best to build a special shed to stabilize humidity in the first three or four days, so that you do not need so high humidity behind, and you can open the greenhouse for ventilation.

The temperature should generally be controlled between 25-30 ℃, not more than 30 ℃, less than 15 ℃, otherwise it is not conducive to the growth of cucumber grafted seedlings in the later stage.

The light can not be too strong, it is necessary to do a good job of shading, otherwise there will be sunburn, resulting in the death of the whole plant.

4. Other key points

When grafting cucumbers, we must pay attention to several aspects:

First, the selection of grafted rootstocks must conform to the local environment and grow plants as grafted rootstocks

Second, the nutrient soil needed by the grafted seedbed must be allocated according to a certain proportion, and the seedbed should be watered before.

Third, the grafted cucumber seedlings should be moisturized, it is best to move to the nutrition bowl, and then build a greenhouse.

Fourth, grafting tools must be disinfected in advance to avoid infecting plants.

To sum up, have you mastered the key points of grafting cucumber seedlings? In order to improve the yield and quality of cucumber, you might as well give it a try.
