How to manage grafted eggplant seedlings? The latest technical method tutorial is here
Eggplant is a very popular gourd vegetable in our daily lives. Market demand is relatively large, so the planting area of eggplant is also relatively wide now. When planting eggplant, the commonly used propagation method is generally grafting. After eggplant is grafted, attention should be paid to management work. So how exactly should it be managed? Below, the editor brings you the management techniques for grafted eggplant seedlings. Let's take a look!
1. Temperature control
After grafting, the temperature of eggplant seedlings should be well controlled. The suitable temperature should be maintained at around 25 degrees to promote wound healing. The seedbed temperature should be controlled at around 25 degrees within 4 days, and the maximum must not exceed 28 degrees. At night, an appropriate day-night temperature difference should be maintained, with the temperature controlled at around 21 degrees, and the minimum must not be lower than 16 degrees. Temperature is very important to the growth and development of grafted eggplant seedlings, and it is also the key to ensuring wound healing after grafting eggplant seedlings. Therefore, after grafting, we must pay attention to controlling the temperature well to ensure the normal growth of grafted seedlings.
2. Humidity adjustment
Humidity is also the key to whether grafted seedlings are successfully grafted. Likewise, during the first 4 days, the humidity in the small arched shed of the seedbed should be controlled at around 92%, and then cooling can begin on the fifth day. The cooling method can mainly be ventilation, but humidity should also be maintained at around 85%. This is because grafted seedlings have relatively high water requirements. In an environment with suitable humidity, the growth rate of grafted seedlings speeds up, and their growth capacity is also strengthened. It is also very beneficial for later flowering and fruiting, so humidity control is also something we cannot ignore.
3. Shading management
During the grafted seedling stage, we should pay attention to shading work. For shading, straw curtains and the like can be used to cover the small arched shed. If it is cloudy, then shading is not necessary. Within 3 days after grafting, full shading treatment should be carried out, and then starting from the 4th day, appropriate light can be provided in the morning and evening each day. However, shading treatment should still be carried out at noon, and then the shading material can be gradually removed as time goes on.
When the temperature is relatively low, the time for eggplant to receive light can be appropriately advanced, and the surrounding temperature can be raised to promote faster wound healing. On the contrary, if the temperature is high, shading work must be done well at noon to avoid direct sunlight on the seedlings. Under normal management, the graft union will fully heal after about half a month. After healing, the clips can be removed and normal management can be carried out. When the rootstock of the grafted seedling grows lateral buds, they should be removed on a sunny morning to avoid consuming too much nutrients and to prevent the wound from being invaded by soil-surface pathogens.
The above is a brief introduction to the management techniques for grafted eggplant seedlings. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
