Greenhouse eggplant management technology

Eggplants are grown in greenhouses in winter, so how to manage them?

1. Temperature management:

No ventilation or less ventilation within one week after planting to increase the ground temperature and promote seedling growth. After the seedlings resume growth, proper ventilation and cooling should be carried out to prevent the seedlings from growing too long and keep the seedlings solid and the leaves dark purple. After entering the fruiting period, with the increase of external temperature and watering amount, the ventilation volume should be increased.

2. Water and fertilizer management:

After planting, water once a week to slow down the growth of the seedlings. In the future, control the water to slow down the seedlings and promote the development of the root system. When most of the eggplants begin to swell, stop slowing down the seedlings and apply a small amount of quick-acting fertilizer in combination with watering to accelerate fruiting. After the eggplants are harvested, the ridges can be sealed, and 20kg of ammonium carbonate or 50kg of decomposed chicken manure can be applied in combination with sealing the ridges. After entering the harvest period, due to the increase in temperature and ventilation, water management should be strengthened to increase yields.

3. Cultivation and loosening of soil:

After the seedlings have grown, loosen the soil in time to increase the root temperature. After the eggplants are harvested, start sealing the furrows. The original planting furrows are sealed with soil to form small high ridges, and watering furrows are opened between the rows.

4. Protect flowers and fruits:

The humidity in the greenhouse is high, the ventilation is poor, and it is difficult to pollinate, so hormone treatment must be used to achieve fruit setting. Generally, 20-30 mg/kg of 2,4-D is used to apply to the stigma or spray the flowers. Once a day, it cannot be repeated.
