Purple eggplant is a Solanaceae, a plant of the nightshade family, up to 1 meter high, the twigs are mostly purple, and the wild ones often have skin nuclei such as thorns, and the hairs will gradually fall off when they get older. The leaves are large, ovate to oblong-ovate, and the petioles are about 2-4 cm long.

1. Eggplant is generally planted in early spring or early autumn, matured and harvested in March-April or September-October, and the growth cycle is about 1-2 months. The main varieties can be divided into round eggplant, long eggplant, dwarf eggplant, etc. according to the variety. Eggplants can be grown at other times, but the yield is relatively low.

2. Eggplant is native to tropical Asia and is distributed all over the world, and is cultivated more in Asia, accounting for about 74% of the world's total output; Europe is the next most, accounting for about 14%. It is cultivated in various places and is one of the main vegetables in summer.

3. Solanto likes high temperature, the suitable temperature for seed germination is 25 -30, the suitable temperature for seedling development is 25 -30 during the day, 15 -20 at night, and the growth below 15 is slow, and causes flower drop. Metabolism is out of balance when it is less than 10. Eggplant has high requirements for light time intensity.

Under the conditions of long sunshine and high intensity, eggplant has vigorous growth, flower buds, high fruit yield and good coloring. The water requirement is less before the formation of eggplant, and more water is needed after the rapid growth of eggplant, and the water demand is large before and after the eggplant harvest, so it is necessary to meet the water demand. Eggplant likes water and is afraid of water, and when the soil is moist and poorly aerated, it is easy to cause roots, and the air humidity is high and it is easy to cause diseases.

Eggplant has higher requirements for nitrogen fertilizer, delays flower bud differentiation when nitrogen is deficient, and the number of flowers is significantly reduced, especially in the peak flowering period, such as rent, if nitrogen is insufficient, the short column flowers become more, and the plant development is not good with hail. Under the condition of low nitrogen fertilizer level, the effect of phosphate fertilizer was not significant, and the potassium uptake increased sharply in the later stage.

The life span of an eggplant is 1-3 years, the eggplant planted in the open field in the north will die after a year, and the eggplant cultivated in the greenhouse can survive for 2-3 years, and the growth cycle of the eggplant is 50-60 days, sown in spring and autumn every year, and can be harvested after two months, and its growth cycle is divided into four stages: germination period, seedling stage, flowering period and fruiting period.
