Management Technique of Eggplant Seedling Stage

Eggplant is a kind of fruit and vegetable vegetables that many people like to eat very much, and its planting area in our country is very large. When planting eggplant, we should do a good job of management according to the growth period of eggplant. Especially in the eggplant seedling stage, its management is particularly important, so we must pay attention to do a good job in eggplant seedling management. So how to manage it? Today, the editor brings you the management technology of eggplant seedling stage. Let's take a look at it together.

1. Temperature management

Eggplant before emergence, its daytime temperature should be maintained at about 25 degrees, make a good airtight film. Pay attention to covering the grass every morning, and then uncover it every night. It can accelerate the unearthed time of eggplant seedlings, in the period from eggplant emergence to seedling division. The temperature during the day should not exceed the range of 25-28 degrees, and the temperature difference between day and night should be kept at about 10 degrees. When the seedlings are unearthed, remove the plastic film to provide light. After dividing the seedlings, the temperature remains the same, but one week before planting, attention should be paid to properly cooling and refining the seedlings. When the heart leaves of eggplant seedlings grow, increase ventilation and gradually cool down to avoid the phenomenon of flashing seedlings.

2. Soil cover in different stages

When sowing, we need to cover a layer of fine soil. Then when the eggplant is in its seedling stage, we should also pay attention to doing a good job of covering the soil in stages. Generally speaking, it is necessary to cover the soil properly after the emergence of eggplant seeds and seedlings. In addition, each time the seedlings and watering, it is necessary to cover a layer of fine soil. Before covering the fine soil, we all need to prepare in advance. Should cover the fine soil should be preheated in the greenhouse after use, and then pay attention to the thickness of the soil, not too thick, should be kept at about 0.2 cm.

3. Weeding between seedlings

In the eggplant seedling stage, we also have to do a good job of seedling work. Usually the whole seedling stage should be about twice, first of all, it should be carried out before dividing the seedlings. When the seedlings grow about two cotyledons, the seedlings are interspersed for the first time. To sparse the overgrown seedlings, the distance between each robust seedling should be kept at about one centimeter, leaving no two. Then the second interseedling work was carried out when the first true leaf of the seedling was unfolded, and the distance between the seedlings was controlled at about two centimeters according to the principle of keeping the quality and getting rid of the inferior. Then in the seedling, we should also pay attention to do a good job of weeding to prevent weeds from grabbing the growth and nutrition of eggplant.

4. Divide seedlings in time

When the eggplant seedlings grow about 3 leaves, we need to do a good job of dividing the seedlings. If the time of seedling division is too late, it will lead to overcrowded growth of eggplant seedlings and affect flower bud differentiation. About three days before the seedling division, we should water once to facilitate the later stage of the seedling, to prevent damage to the roots. Then when the seedlings rise again, they should be graded according to the size of the seedlings and planted separately. And before dividing the seedlings, we should install the soil in advance to flatten it, control the row spacing at about 10 centimeters, dig a planting ditch with a depth of about 3 centimeters, and then pour an appropriate amount of warm water to start dividing the seedlings.

The above is a brief introduction of eggplant seedling management technology. That's all for today's introduction. This article is for reference only. I hope it can help you all.
