Eggplant is a kind of vegetable that everyone likes to eat. This season is when autumn candels are on the market in large numbers, but it hasn't been long. When the temperature drops below 17℃, the open field eggplant will basically withdraw from the market. Because of the temperature drop, the eggplant is poorly pollinated, and the flower fall is heavy. Even if the fruit can sit on the fruit, it will be crooked, and the seeds exposed. fruit. Furthermore, the eggplants wilt when exposed to frost.
The eggplant seedlings are sown from the end of August to the middle of September. The temperature and light in autumn are suitable for growing seedlings. Before sowing and raising seedlings, apply sufficient base fertilizer to do border sowing, set up a small arch shed on the border, which was initially used for shelter from rain and later for heat preservation.
Water the seedlings in time after they are unearthed. You can use a watering can to spray water to prevent the seedlings from drying out. After the seedlings emerge and time, the seedlings should be weeded to prevent affecting the growth of the seedlings. Eggplant seedlings are prone to rooting, so they should be drained in time to prevent waterlogging after heavy rains.
When the eggplant has 1-2 true leaves, it is time to divide the seedlings. The construction of sub-seed borders is the same as that of nursery borders, flat borders or half-height borders with a width of 1, 2–1, and 5 meters.
Seedling division should be done on cloudy days or in the afternoon. Seedling division under split sun will easily cause seedlings to wilt and reduce survival rate. The separated seedlings are mostly 10x10 cm square from here. Water the seedlings in time after dividing the seedlings, and pay attention to shade at noon to prevent the seedlings from wilting. Generally, cover for 1–2 days, and the time is from 10 am to 2–3 pm.
After splitting the seedlings and slowing the seedlings, water them appropriately, watering once every 5-7 days to keep the soil in the border moist, and hoe the soil in time. If the soil is short of fertilizer, you can chase compound fertilizer every 10-15 days, and chase 6-10 catties each time.
Apply enough base fertilizer in the planting shed, combined with deep turning, and add superphosphate, or ternary compound fertilizer, to make small high bed colonization. It can be covered with plastic film before or after planting, soaked by watering. We are usually planted in the shed from the end of October to the beginning of November.
Field management is mainly light, temperature, fertilizer and water, pruning and other management.
The light management is mainly to uncover the late cover grass thatch, clean the shed film in time, and maintain a good light transmittance.
The temperature is mainly maintained at 25-30℃ during the day and 15℃ at night. It can be adjusted by opening and closing the vents and uncovering the grass thatch. In order to improve the cold resistance of plants in late winter, you can spray potassium dihydrogen phosphate, sucrose solution, or antifreeze, etc., spray once every 3–5 days.
