1. Variety selection

The eggplant planted in the greenhouse should choose the seed quality, and the varieties with full grains, strong disease resistance and low temperature tolerance must be selected, so as to ensure better germination and drying of the seeds in the greenhouse, and soak the seeds with carbendazim before. After the seeds germinate and break their shells, sow them evenly on the prepared soil. When covered with fine soil, once watered, it can be transplanted when the seeds grow 4 leaves, and the transplanting should be carried out with soil to facilitate survival. Generally, about 2000 plants per mu can be transplanted, which can maintain excellent air permeability. in addition, proper ventilation can make the seedling stem grow stout, and the fruit setting rate is also relatively high.

2. Temperature control pier seedlings

After transplanting, the most important thing is to control the temperature and carry out pier seedlings. if the temperature in the greenhouse is high at noon, then the temperature should be cooled through ventilation to keep the temperature at about 28 degrees, which is suitable for the growth of eggplant, and the temperature should not be lower than 10 degrees at night, otherwise it will lead to freezing injury of eggplant seedlings. When the seedling grows to 5 leaves, it is necessary to strengthen fertilizer and water management, dig a small hole to fertilize when it is about 10 cm away from the root, and irrigate after mulching, which can promote the root system to absorb fertilizer as soon as possible and improve fertilizer use efficiency.

3. Pinching bifurcation

Eggplant needs to pinch when growing, to remove some of the branches and leaves, leaving the main stem, so that layer by layer can blossom and bear fruit. In the management, it is necessary to remove the flowers and small fruits in time, generally leaving 3-4 flowers on the first floor, so that 3-4 eggplants can bear fruit, do not leave too many fruits, otherwise it will make the eggplant grow badly.

4. Heat preservation

When it comes to the cold winter in November, it is necessary to cover the greenhouse with a straw mat to keep warm. Every day from 5pm, it is necessary to cover the straw mat and cover it layer by layer, so that the exposure of plastic foam can be reduced and the heat preservation can be excellent.
