Key techniques of grafted Cucumber Seedling Management

Cucumber is cultivated in all parts of our country, and it is a kind of melon vegetables. At present, in order to control soil-borne diseases, most of the seedling methods of planting cucumber are based on grafting. The management of cucumber grafted seedlings is very important, so how should we manage cucumber grafted seedlings? Today, the editor brings you the key technology of cucumber grafted seedling management. Let's take a look at it.

1. Pay attention to heat preservation

Temperature is very important for the survival of cucumber grafted seedlings. Therefore, after cucumber grafting, the first thing we need to do is to keep warm. If the temperature is not suitable, it will affect the healing of cucumber grafted seedlings, if the temperature is too low, then the grafting interface of grafted seedlings is difficult to heal in low temperature environment, resulting in a decline in survival rate. So after grafting, we should keep the temperature at about 25 degrees to promote the healing of the grafting interface and improve the survival rate.

2. Pay attention to moisturizing

In addition to temperature, humidity is also very important for the growth of cucumber grafted seedlings. If the air humidity in the grafted seedbed is too low, the cucumber scion will wither due to lack of water, resulting in a decline in the survival rate of grafted seedlings. Therefore, after grafting, we must pay attention to control the humidity. Within 4 days after grafting, the air humidity in the seedbed should be controlled at about 90%.

3. Pay attention to shading

Light also has a great relationship with the growth of cucumber grafted seedlings. If the grafted seedlings are raised and grown in the greenhouse, then we should pay attention to covering some sparse grass curtains or sunshade nets outside the shed. Prevent grafted seedlings from being exposed to direct sunlight, causing water to evaporate too quickly, resulting in wilting of the scion. And in the evening, it can also play the role of heat preservation, which is very beneficial to the growth of cucumber grafted seedlings.

4. Pay attention to ventilation

Ventilation is also a key point in the management of cucumber grafted seedlings. If cucumber grafted seedlings grow in an environment with poor air circulation and poor ventilation, then the growth of cucumber grafted seedlings will be affected because of poor air quality. Therefore, we can start to ventilate when the grafted seedlings survive and begin to grow about 4 days after grafting. At the beginning, the vent should not be too large, it is necessary to slowly expand the vent, so that the grafted seedlings have a process of adaptation.

5. Scion root cutting

Finally, we still need to do a good job of cutting the root of the scion for the grafted cucumber seedlings. Because if the scion is not cut off in time, the root of the scion may continue to grow, resulting in the loss of value of the grafted seedling. Therefore, for cucumber seedlings raised by grafting, about 10 days after transplanting, the scion should be cut off in time to avoid excessive rooting and affect the growth of grafted seedlings.

The above is a brief introduction to the key techniques of cucumber grafted seedling management. That's all for today's introduction. This article is for reference only. I hope it can help you all.
