This variety can be cultivated in early maturity and overwintering, and its plant type belongs to upwelling type, which is especially suitable for close planting in protected areas. Early-maturing eggplant seedlings should have 8 ~ 9 real leaves when planting, and should be raised in a nutrition bowl from sowing to initial harvest 100 ~ 105 days. This variety is suitable for close planting, with a spacing of 40 cm and a row spacing of 50 cm. Generally, about 3300 plants are planted every 667 meters. After 4 ~ 5 days of planting, the seedlings can resume growth, and manure or chemical fertilizer can be applied to raise seedlings, which is generally carried out in combination with shallow tillage. Before flowering, the supply of fertilizer and water should be properly controlled to facilitate flowering and fruit setting. According to the growth of plants, if the base fertilizer is sufficient and the plants grow well, no fertilizer can be applied. If the base fertilizer is insufficient and the plants grow badly, the diluted human and animal feces can be chased once. The third layer will harvest fruits from fruit setting to fruit harvesting. Plants will continue to grow branches and leaves and continue to blossom and bear fruit. Fertilizer and water should be supplied in time, irrigated every 4 ~ 6 days and applied with quick-acting fertilizer. After the third layer of fruit is harvested, it is the full fruit period. At this time, the weather is getting hotter and hotter. In addition to paying attention to water supply, it is generally necessary to harvest and fertilize once.

The flowering period of Meneggplant is just when the temperature is uncomfortable, so we should pay attention to protecting flowers and fruits. Before the shining period of Meneggplant, the fruit growth was relatively small, and it was still a transitional period of vegetative growth and reproductive growth. Therefore, measures should be taken to squat seedlings during intertillage to properly control the crazy seedlings caused by excessive nutrient growth. At the end of eggplant development period, squat seedlings, topdressing and watering in time. The lateral branches germinate easily in the axils of the lower leaves of eggplant.
