Detailed Explanation of the Latest Management Key Points for Early Spring Vegetable Transplanting

It is now exactly the time for early spring vegetable transplanting. If the transplanting time or the transplanting water is not right, the survival rate of the seedlings after transplanting will drop greatly. So how should management be carried out during early spring vegetable transplanting to make the crops grow better? Let's take a look together below.

1. Transplanting time

In order to cultivate strong roots, it is recommended to limit transplanting to sunny weather, and it is best to maintain 2-3 consecutive good weather days. If transplanting is carried out under sunny conditions, the seedlings will show slight wilting, but this wilting is the seedling's self-regulation, a change the seedling makes to adapt to the environment. Doing this not only reduces water evaporation from the plant body, but also prompts it to grow newer and deeper. At the same time, transplanting small seedlings is more conducive to seedling recovery. After 2-3 days, as new roots grow, the plants enter a normal growth state and will not show acute wilting.

2. Transplanting method

For crops transplanted in early spring, no matter what the crop is, ridge planting must be used, because at this time the soil temperature is still low and the air temperature is low. Ridge cultivation is conducive to seedling recovery and can also raise the soil temperature. When transplanting, plant and row spacing is also extremely critical. Be sure to note that flat-bed transplanting must not be used. The plant and row spacing at transplanting should not be too dense or too sparse, otherwise it will have a great impact on later yield. When transplanting, it is generally necessary to plant a bit shallowly, because early spring temperatures are low and planting too deep makes it difficult for roots to develop.

3. Temperature and humidity management

During transplanting and seedling recovery, the day-night temperature difference should be appropriately widened for seedling hardening, so as to promote the seedlings to become stronger. Generally, legume vegetables should be kept at 26-28 degrees during the day and 12-14 degrees at night; solanaceous and fruiting vegetables should be kept at 25-28 degrees during the day and 12-14 degrees at night; melon and fruit vegetables should be kept at 26-30 degrees during the day and 14-15 degrees at night. In addition, the humidity inside the greenhouse should be controlled at 70%-80% as much as possible. When humidity is too high or the soil temperature is [too low], appropriate ventilation is needed, which can also prevent [disease] occurrence. When necessary, a dehumidifier should be used to dehumidify the interior. When humidity is too low, spraying water can be used to increase humidity.

4. Fertilizer and water management

After transplanting, reasonable watering is needed to keep the soil moist, so as to prevent the plants from wilting. Generally speaking, the seedling recovery water should be given about one week after transplanting, chosen on a sunny day. It is best to apply a small amount of water under the film. After watering, pay attention to raising the [soil] temperature, and ventilate in time to remove moisture. When watering, clean water quality should be chosen to prevent algae from growing and clogging drip irrigation pipes. At the same time, timely topdressing should be combined with watering. When base fertilizer is sufficient, the amount of fertilizer used at transplanting is not much. The main purpose is to promote root growth, and using functional fertilizers well is enough.
