Early spring seedling seedlings

After the seedlings are unearthed, strong light and long illumination time should be given. For breeding seedlings of thermophilic vegetable seedlings, the temperature should be controlled between 20°C and 25°C during the day and 13°C~16°C during the night; the temperature should be controlled at 18°C ​​during the day when the seedlings of the cool young vegetable seedlings are cultivated. °C~22°C, control the temperature at 8°C~12°C at night. During management, cover the opaque cover early and increase ventilation and ventilation time. In addition, 1 to 2 fine dry soils should be sprinkled on the bed surface to avoid cracking and reduce water evaporation. When seedlings are planted in early spring, seedlings can improve lighting conditions and nutritional status of seedlings, and are important measures for cultivating strong seedlings. The vegetables that must be divided into seedlings include tomatoes, eggplant, spicy (sweet) peppers, cabbage, broccoli, etc. The melons and legumes can be divided. 3 to 5 days before seedling, the temperature in the bed is appropriately lowered and the seedlings are grown at low temperature. Sub-seedlings should be selected for sunny and warm weather. The seedlings should be sprayed on the bed the day before the seedlings to facilitate seedling growth. After the seedlings were divided, the spacing and spacing of the seedlings of the eggplant vegetables were 10cm, and the spacing and spacing of the cabbage seedlings were 8cm. When the seedlings are divided, the seedlings usually use dark water seedlings, that is, they are divided into 6 to 8 cm depths and widths in the sub-seedlings. The pots are used to water the pots in the pots, and the seedlings are planted on the sides of the gullies according to the plant spacing. The water seeps. After the cover soil will be planted seedlings. Immediately after seedlings, the plastic film is covered to increase the temperature of the seedlings and promote the seedlings to take root and shoots. For example, if the seedlings are wilted under the hot sun at noon, a small amount of grasshoppers can be covered and shaded in the afternoon.
