Key points of management before and after planting vegetables in early spring

The low temperature in early spring and timely planting of vegetables are not only beneficial to slow down the seedlings of vegetables. It also helps to increase the cold resistance of plants, but the management before and after vegetable planting is also very important. So how to manage the vegetables before and after planting? Come and have a look with the editor.

1. Low temperature seedling refining

Low-temperature seedling refining can obviously increase the cold tolerance of vegetable seedlings, which is beneficial to slow down vegetable seedlings. Low-temperature seedling refining work is generally carried out 7-10 days before vegetable planting, and the actual seedling refining can not be too long, otherwise it will cause seedling freezing damage. The temperature of the nursery bed should be controlled at about 15-20 degrees during the day and 8-12 degrees at night, so as to improve the cold resistance of the seedlings. When refining seedlings at low temperature, the temperature of the seedling bed should not be too low, otherwise it will seriously affect the normal physiological function of the root system, and the phenomenon of aging and rigid seedlings will easily occur.

2. Buckle the shed ahead of time

In order for the seedlings to be planted slowly as soon as possible, the greenhouse needs to reach a suitable temperature, especially for melons and fruits such as tomatoes, eggplants and cucumbers, which have high requirements for ground temperature and temperature. the soil temperature of 5-10 cm is required to reach more than 15 degrees, and the minimum temperature should not be lower than 10 degrees, so as to ensure their normal growth. Therefore, 7-10 days before seedling planting, plastic film should be used to cover and seal the greenhouse to increase the ground temperature.

3. Timely planting

Although the temperature in early spring is rising, the temperature is unstable, and it is extremely prone to adverse weather such as late spring cold, strong wind and frost, so we must pay attention to the weather forecast before planting vegetable seedlings, requiring that there should be no cooling, rain and snow within 5-7 days. Only in this way can we slow down the vegetable seedlings. If there is a low temperature and bad climate in the next few days, it is necessary to delay colonization and avoid this period.

4. Strengthen the heat preservation

After the seedlings are planted, the heat preservation must be strengthened to promote the seedlings to slow down. Within 3-5 days after planting, the greenhouse should be airtight, and the temperature of the greenhouse should be raised appropriately. Different needs to be kept at 28-30 degrees. See you at night, and stay above 20 degrees at night. When there is a strong wind, cover the insulation at night to avoid excessive heat dissipation at night, causing the temperature in the shed to drop too fast. In addition, laying straw or straw between rows can not only increase the ground temperature, but also reduce the humidity in the greenhouse and promote the growth and health of seedlings.

The above is the introduction of the key points of management before and after planting vegetables in early spring. I hope it can help you. If you want to know more about it, please follow us.
