The eggplant seeds were soaked in wood vinegar with different densities, aiming at researching the effects of wood vinegar on seed germination. The results showed that all treatments had obvious effects on the seed germination rate, the germinating index and the seed germinating energy. The best density was the dilution rate of 400-200, the peak value time of germination in the experimental group occurred on the third day or the forth day, but the worse density was the dilution rate 100-50. At the same time, the prediction model of the seed germination rate was founded. The model showed the dynamic relationship among the rate seed germination, the time, and the density. The average relatively error(E) and correlation coefficient (R2) of the model was 5.153% and 0.990621, respectively, which showed the most optimized prediction among predicted values by BP neural network model and the measured values of eggplant seeds germination rate.
