Key points of management techniques for cross pollination of eggplant

The optimum temperature for eggplant flowering and fruiting is 25: 30 ℃, below 17 ℃, above 40 ℃, and can not be fertilized. The flower blossoms at about 6 o'clock in the morning, and the anther begins to crack after 7 o'clock, so the suitable pollination time every day is after 8 hours. Cross pollination should be in the afternoon one day before the female flower blossoms, choose Corolla protruding bud lhand 2, lilac, unopened buds must be castrated, castration must be thorough, so as not to produce false hybridization. On the second day after castration, the male parent was pollinated when the flower bloomed (the pollination rate of the pollen blooming on the same day was the highest), and the pollen was smeared on the stigma of the female parent. Eggplant (2 fruits) and Simandou (1 fruit) should be hybridized, and all other buds should be removed after fruit setting. According to the experiment, repeated pollination can increase the seed yield of F1 (hybrid generation) by 10%. For hybrid fields, we should strengthen field management, timely control of diseases and insect pests, irrigation during severe drought, timely drainage after rain, and pay attention not to make the seed fruit touch the ground. 55-60 days after pollination, the seeds were fully yellowish brown and ripe, and after 5-7 days of ripening, the seeds were cut and bagged until the moisture content of the seeds was about 7%. Store them in dry and cold conditions.
