Seedlings in greenhouses can be found in the nursery of the greenhouse in the previous section. Eggplant seedlings are most afraid of desiccation. The ratio of garden soil in nursery beds is slightly larger than that of cucumbers and tomatoes, that is, 6 garden soils, 4 composts, 1 decomposed horse manure, 100 g nitrogen fertilizer per cubic meter, and 200 phosphate fertilizers. Grams, potassium 100 grams, and should be mixed and stacked one month before sowing. The bottom water before sowing should also be larger than tomatoes. Some places are planted with sowing boxes, which can be placed on the warm ground near the fire lane. The solar greenhouse also needs to be in the best conditions of lukewarm light conditions, which is conducive to the high temperature demand of eggplant. In two sub-seedlings, the first time can be carried out after the two true leaves are unfolded, roughly about 25 days after sowing, with a spacing of 10 cm and 10 cm. It is before the first flower differentiation. The second sub-seedling should be carried out 20 to 25 days after the first sub-seedling, after the seedlings grow 4 true leaves. In this sub-seedling, plans to plant the greenhouse, one can all be divided from the greenhouse to the greenhouse, so the training of the seedlings is even more important, and the ventilation should be started a week before the transplant, especially to lower the temperature at night to maintain 13~ 15 °C, and should be consistent, tightly, do not make the seedlings in the cold after going through the open, it is best when the sunny days when the seedlings. Immediately after moving into a large shed, cover a small arch shed, cover the straw mat at night, and cover it around. If it is necessary to conduct the third sub-seedling, it can be carried out 25 days after the second sub-seedling, further increasing the nutritional area. The colonization of eggplants in greenhouses is a large seedling of 10 to 12 true leaves. The management of seedlings is of utmost importance. In order to develop ideal seedlings, the seedbed temperature can be gradually reduced from 28 to 30°C to 23 to 25°C and gradually decreased to 13 to 14°C at night. The nighttime temperature has a great influence on the quality of the flowers. Excessively high nighttime temperatures often degrade flower quality, increase flowering, and increase short flowering. And can increase the flower's pitch. If the first flower is opened at the seedbed 90 days after sowing, the 2,4-D should be timely applied and all the lower lateral branches should be removed. The measures to prevent falling flowers and forming stone eggplants are to ensure light, provide nutrition, avoid temperature fluctuations, and pay attention to soil moisture. As for the sowing time, it can be calculated 90 to 100 days in advance according to the local greenhouse planting period. Varieties are generally based on local stable production of high product species, but also refer to the selection of solar greenhouse varieties.
