Eggplant seedlings are squatted twice, it is important to control moisture and temperature.
Squatting for the first time:
Seedling refining: Eggplants are sown for about 25 days, and the eggplant seedlings are divided into seedlings when they reach five leaves and one heart, and the seedling beds of the seedlings should be fully soaked. The seedlings are divided according to the row spacing of 10 cm × 10 cm, and the transplanting depth of the seedlings is generally about 2 cm (do not bury the cotyledons).
Control the temperature: cover the sunshade net and increase the air vent. After the seedling is divided, during the seedling period, the temperature in the day is controlled at 28 ℃ ~ 32 ℃, at night controlled at 20 ℃ ~ 25 ℃, to suppress the seedlings from growing.
Watering control: Eggplant seedlings should be watered as little as possible, and the growth of seedlings can be adjusted by controlling the amount of watering. Before planting, in order to facilitate seedling slowdown, be sure to bring soil and tufts for planting (appropriate amount of water can be sprayed to make seedlings and tufts). Experts remind everyone that when the seedlings have a long phenomenon (the seedling age reaches more than 20 days), they can be planted in advance.
The second squat:
After the second squat planting, after planting, you can take measures to control the temperature of the shed and manage the fertilizer and water reasonably.
Control temperature: the best temperature range after planting, the temperature should be controlled at about 28 ℃ in the daytime and about 15 ℃ at night. As the light intensity decreases during the daytime, the temperature decreases, and the air volume can be increased appropriately on sunny days to maintain around 15 ℃ Day and night temperature difference. When the light is too strong at noon in summer and autumn, a shading net can be set for shading.
Control watering: After watering and planting water, hoeing should be carried out in time to maintain soil moisture. In order to enhance the lignification of eggplant seedlings, the number of watering and the amount of watering must be controlled in the early stage. Don't rush to watering and topdressing when you have white hairy roots. Use this time for the second squat seedlings to promote root ligation, "root depth is leafy".
After two squatting seedlings, the eggplant stalks are reddish in color, the internodes are short and thick, and the leaves are dark and thick, which is a remarkable feature of high yield and high yield in the future.
