How can the fruit-setting rate of eggplant be increased? What methods can make eggplant set more fruit? Experienced readers are also asked to help share their knowledgeEggplant can be planted in all four seasons, but the low fruit-setting rate of eggplant is a common headache for vegetable growers, so Zhongdi Network has compiled four methods to increase the fruit-setting rate of eggplant, listed below for readers' reference.
Method one: Pinching off the growing tips of eggplant:
The fruit-setting pattern of eggplant generally increases as the plant branches, and basically each branch sets one fruit. In planting management, this characteristic should be fully utilized by pinching off the growing tips promptly after transplanting, so as to promote rapid branching, increase the fruiting positions, and raise the fruit-setting rate.
Method two: Promote weak plants and control excessive vigor in eggplant plants:
Generally, if eggplant plants grow weakly and lack nutrients, flower and fruit drop will worsen; but if they grow too vigorously, nutrients will also become relatively insufficient and cause flower and fruit drop. Therefore, maintaining normal growth vigor is the basic requirement for promoting flower formation and fruit setting in eggplant.
Therefore, for weakly growing plants, fertilizer and water should be increased to strengthen their growth vigor; for overly vigorous ones, fertilizer and water should be appropriately controlled to help them return to normal growth, so as to increase the fruit-setting rate.
The specific method is: when strengthening fertilizer and water management for weak seedlings, organic fertilizer and quick-acting phosphorus should be the main focus in the early stage, and quick-acting nitrogen fertilizer should be used in the middle and late stages. Preferably at flowering, apply 500-600 kg of decomposed dilute manure per mu, or 20-30 kg of cake fertilizer, plus 15-20 kg of superphosphate. After entering the full fruiting period, topdressing should shift to quick-acting nitrogen fertilizer as the main type (apply 10-15 kg of urea per mu each time), with 3-5 topdressings during the fruiting period.
Method three: Use hormone treatment:
Spraying flowers with 20 ppm of anti-drop agent during the flowering period, or dipping flowers with 30-40 ppm of 2,4-D, can both prevent flower and fruit drop, thereby increasing the fruit-setting rate.
Method four: Carry out artificial pollination:
Eggplant flowers open at around 6 a.m., and the anthers begin to split after 7 a.m., so the suitable pollination time each day is after 8 o'clock. For cross-pollination, on the afternoon of the day before the female parent flower opens, select buds whose corolla has extended l/2, are light purple, and have not yet opened, and emasculate them. Emasculation must be thorough. On the second day after emasculation, when the male parent flower opens, collect pollen (pollen from flowers opening that same day gives the highest fruit-setting rate), and smear the pollen onto the stigma of the female parent.
