How to grow eggplant seedlings?

Today I will introduce to you the eggplant seedling raising technology. It is very important. Please save it well:

eggplant

Overview

Eggplant seedlings grow slowly, especially under insufficient temperature conditions. The seedlings are not old enough, making it difficult to cultivate early-maturing large seedlings. The seedlings generally need to be 85-90 days old.

In order to prevent sudden wilt and damping-off disease in the seedling stage, in addition to paying attention to maintaining a suitable soil temperature at night, you can also use "Fifth Generation Agent" (a mixture of equal amounts of pentachloronitrobenzene and mancozeb) to disinfect the soil. Use 8-9g of disinfected soil per square meter of seedbed and mix it evenly with the bed soil. After using the medicine, the amount of irrigation should be appropriately increased to prevent drug damage. The bed soil should be fertile and not too dry.

sowing

The seedling raising methods of eggplants are basically the same, and the seedling raising methods are all greenhouses, hotbeds or sunbeds. However, it is difficult to germinate eggplants, and the temperature requirements are relatively high. Before sowing, use 55-60℃ warm water to scald the seeds, stir while pouring, and stop stirring when the temperature drops to about 20℃. Soak for a day and night, remove them, rub off the mucus on the seeds, rinse them with clean water, and place them in a place with 25-30℃ for germination. During the germination period, the environmental humidity should be maintained at 85%, and 30%-500% of the seeds are white before sowing. When sowing, sprinkle the seedbed with warm water first, then evenly spread the seeds in the bed, and cover them with fine soil 0.8-1cm thick.

Cover the shed immediately after sowing, and cover with straw thatch to keep warm at night. Keep the bed temperature at 26-28℃ during the day and around 20℃ at night before emergence. 50%-60% of the seedlings will emerge in about 4-5 days. Lower the temperature in time after emergence to around 25℃ during the day and 15-17℃ at night. It may be slightly lower on cloudy days.

Seedling division

When the seedlings have 2 to 3 true leaves, they can be transplanted. The main method of transplanting seedlings is to transplant them into sunny beds or plastic arch sheds. The bed soil should be fertile, especially a certain amount of quick-acting nitrogen fertilizer. In addition, a certain amount of nutrient area should be retained for each transplanted seedling, preferably 10cm×10cm.

After transplanting, the plastic arch shed should be covered immediately. At night, it must be sealed with straw thatch and kept at a certain temperature (up to 20-25℃). After the seedlings have grown, ventilation and cooling should be started. The temperature should be 25℃ during the day and 15℃ at night. Special attention should be paid to prevent the high temperature at noon on sunny days from "burning the seedlings". If the fertility of the seedbed is insufficient, topdressing should be combined with watering. If the seedbed is compacted, the soil can be loosened with a small tooth rake. The seedlings should be ventilated and hardened 10 days before planting, but frost damage should also be prevented. The standard for strong seedlings is 16-23cm in height, 5-7 leaves, and 0.5-0.7cm in stem thickness.
