Eggplant in greenhouse appears the phenomenon of falling flowers and fruits. How to reduce this phenomenon?

Eggplant is a common vegetable in people's daily life, which is deeply loved by consumers and has remarkable planting effect. With the adjustment of planting structure and the popularization of greenhouse, the planting area of eggplant in greenhouse has expanded year by year. However, there are problems in eggplant planting in greenhouse, which directly affect the income of vegetable farmers. The main reason for the serious flowering and fruit dropping of eggplant in plastic greenhouse is that the flowering temperature of eggplant in plastic greenhouse is too high or too low. Therefore, due to factors such as excessive core density, insufficient illumination and improper fertilizer management, measures can be taken to prevent eggplant from falling flowers and fruits in plastic greenhouse. Strengthen greenhouse temperature control. During the day, the temperature should be adjusted to 25-28, and it should be ventilated in time if it exceeds 30. The temperature at night is suitable 16 ~ 17. Reasonable close planting and timely adjustment of plants. Moreover, in the process of plant growth, it is necessary to remove the lateral branches below the first-grade branches, remove the old leaves and diseased leaves, and strike branches in time to form a suitable plant structure. At the same time, spray Wanghua No.3 to inhibit the vigorous growth of Zhu Cao and promote flower bud differentiation.

Strengthen fertilizer and water management. The water supply management of eggplant in the early stage is mainly controlled, with less irrigation and more loosening, especially in the flowering period. The soil moisture should not be too high. Before flowering, vegetables and Tibet Diying should be sprayed to improve the pollen quality, increase the cyclic fruit setting rate, reduce the occurrence of flower and fruit dropping, and make eggplant produce continuously and stably. When the literary talent grows to the size of a walnut, every autumn rain, irrigation and radish has invested 10 kg of elements. Also pay attention to the simultaneous use of phosphorus and potassium fertilizers. Spray 800 times of new high-fat film to improve the utilization rate of effective components of fertilizer, and use early irrigation and furrow irrigation in sunny days when drinking water. Control pests and diseases. Pests and diseases should be prevented in time at the initial stage. According to the requirements of plant protection, targeted drugs such as 75% chlorothalonil 500-800 times solution and 15% pyridoxine EC 2000 times solution can be sprayed for prevention and control, and 800 times solution of declared plastic film can also be sprayed to improve the utilization rate of effective components of drugs and consolidate the prevention and control effect.

Preventive measures for weak plant growth: choosing mother-in-law when planting, increasing fertilizer at the same time, promoting roots and strengthening seedlings, and spreading strong autumn polyurethane after transplanting seedlings can delay the emergence of seedlings, quickly adapt to the new environment and grow healthily. According to the plant growth, Su Hua implements fruit restriction management.

Eggplant, as an eggplant crop, often drops flowers and fruits during its growth, which greatly reduces the yield of eggplant. Eggplant flowering means that the flowers of eggplant naturally fall off before the eggplant bears fruit. Eggplant fruit dropping refers to the phenomenon that eggplant naturally falls off after 3 ~ 5 days of fruit setting. Generally speaking, the flowering phenomenon of eggplant may be greater than that of eggplant, but sometimes the fruit of eggplant will not fall off, but the fruit can not develop and expand normally. Which is what people call rigidity.
