Due to the high or low greenhouse temperature during the fruiting period, the planting density is too large, the light is insufficient, and the fertilizer and water management are not properly managed. This often results in severe flowering and fruit drop in the greenhouse, which directly affects the income of the vegetable farmers, and corresponding measures can be taken to prevent greenhouses. The falling of the eggplant falls. 1. Strengthen greenhouse temperature regulation. The temperature during the day is controlled at 25-28°C. Ventilation should be promptly performed when the temperature exceeds 30°C. The temperature at night should be 16-17°C. 2, rational close planting, timely adjustment of plants. In the process of plant growth, the lateral branches below the first branch are removed, the old leaves and diseased leaves are removed, the pruning is performed in time, and a reasonable plant structure is formed. At the same time, the promotion of Huawang No. 3 is adopted to suppress the prosperous growth of the main shoot. Flower bud differentiation. 3, strengthen fertilizer and water management. Eggplant early watering management is mainly controlled, less irrigation, more loose soil, especially the soil moisture during the flowering period of the gate, can not be too high, and spraying the fruit Zhuang Tiling before flowering to improve pollen quality, enhance the cycle fruit setting rate, reduce Falling fruits and falling produce stable quality of eggplants. When the door grows to the size of the walnut, top dressing is applied and water is applied, and 10 kg of urea is applied per mu. At the same time pay attention to the application of phosphorus and potassium fertilizers. And spraying 800 times the new high-fat film to improve the utilization of active ingredients of the fertilizer, irrigation, sunny morning irrigation and gutter irrigation. 4, control of pests and diseases. In the early stages of pests and diseases should be controlled. Can be sprayed according to plant protection requirements 75% chlorothalonil 500-800 times, 15% Dai Ling EC 2000 times liquid and other targeted drugs for prevention and treatment, while spraying 800 times the new high-fat membrane to improve the utilization of effective pharmaceutical ingredients, consolidate Control effect.
