Prevention and treatment of eggplant drop in greenhouse

Strengthen the temperature adjustment of the shed during the daytime temperature control at 25 °C ~ 28 °C, more than 30 °C should be timely ventilation; night temperature is 16 °C ~ 17 °C is appropriate.

Reasonable close planting, timely plant adjustment The density of early maturing varieties is preferably 5,500 to 60,000 per hectare. During the plant growth process, the side branches below the first branch are removed, the old leaves and diseased leaves are removed, and the pruning is performed in time to control the rational plant structure.

Strengthen the management of fertilizer and water management. The watering management of eggplant in the early stage is mainly controlled, with less irrigation and more loose soil, especially when the water is not too high during the flowering of the eggplant. Otherwise, it is easy to fall and fall. When the stalk grows to the size of the walnut, it is topdressed and watered, and 150 kg of urea per hectare. At the same time, pay attention to the combined application of phosphorus and potassium fertilizer. In the case of irrigation, in order to prevent the early ground temperature from falling, it is possible to adopt a sunny morning irrigation and a furrow irrigation method.

Timely prevention and control of pests and diseases in the early stage of the disease. Control the brown streak with 75% chlorothalonil 500~800 times solution, and control the red spider with 40% omethoate 1000~1500 times.
