Key Management Measures After Planting Spring Eggplants in Polytunnels
1. Temperature control. For spring eggplants grown in large polytunnels, after the seedlings are planted and before they recover from transplanting, the tunnel should be kept closed to retain heat, keeping the temperature inside the tunnel at 28-30°C during the day and 15-20°C at night as much as possible. After the seedlings recover, attention should be paid to ventilation, keeping the tunnel temperature at 23-25°C during the day, generally not exceeding 33°C. 2. Fertilizer and water management. When soil moisture is good, water as little as possible before the first eggplant (the "door eggplant") reaches the size of a walnut, to raise soil temperature and prevent flower and fruit drop. When the door eggplant reaches the size of an egg, apply 10 kg of urea per mu along with watering. After that, appropriately increase the frequency of watering according to soil moisture conditions.
