Generally, the small arch shed and the mulching film in the greenhouse are used to achieve early planting(flat plastic tray), and the purpose of the morning city cultivation method is better. Choose very early-maturing or early-maturing varieties that are strong in cold resistance, weak in light, short in plant type, and suitable for close planting(gallon nursery pots). The formula for the cultivation of the seedbed is: fresh garden soil, decomposed pig manure residue, 1/3 of the carbonized chaff, and evenly mixed.(large black 20 gallon nursery plant pots for sale)
Soaking seeds are soaked with warm soup or soaked with chemicals(plastic grow pots). Soak the seeds in warm soup, soak the seeds with warm water at 55 °C, stir and keep the water temperature for 15 minutes, and transfer to water at 30 °C for 8 to 10 hours. Soaking seeds, such as preventing eggplant brown streak, can be immersed in warm water for 5-6 hours, then immersed in 1% potassium permanganate for 30 minutes, then rinse thoroughly with water(cell trays). Germination can be carried out in a germination box. Use temperature change treatment.
That is, germination for 16 hours every day at 25 ~ 30 ° C, and then germination for 8 hours under 200C conditions(greenhouse supplies pots), 4 to 5 days can be bud, usually every 8 to 12 hours to flip, clean water, control dry and remind, 80 About % of the seeds are white and sowed. When sowing, first penetrate the bottom water, then sow, 20 to 25 grams per square meter of seedbed(gallon plant pot). Cover the nutrient soil 1~1.5 cm thick, then cover the mulch with the ground cover and seal the shed door.
(large black 20 gallon nursery plant pots for sale)Organic eggplant cultivation techniques in winter and spring(wholesale greenhouse pots), when the bed soil is not exposed, water is poured in time to keep dry and semi-wet. It is also possible to use the brewing heat to warm the seedlings for wintering, and to soak seeds and germination 7 days before sowing. In the case of sunny days, ventilation should be seen as much as possible to enhance the light(plug trays). It can be combined with water spray to apply organic nutrient solution 1 to 2 times.
Then made at 24-26 ° C. 70% of the film was unearthed when it was unearthed(seed starter trays). From the cotyledons to the first true leaf break, it usually takes about 7 days, and should be cooled and controlled. White j temperature should not exceed 25 ° C, ground temperature 18 ~ 20 ° C during the day, 14 ~ 16 ° C during the night. Control the watering with proper ventilation to make the bed white(propagation tray). From the heartbreak period to the fourth true leaf stage, the bed temperature should be controlled between 16 and 23 °C.
Before seedlings, attention should be paid to proper exercise of the seedlings(square nursery pots). 30 to 40 days after sowing, when the seedlings have 3 to 4 true leaves, choose a sunny day with 10 cm x cm of nutrients. Planting should not be too deep, with a flat root neck. After the seedlings, the root water is quickly poured(9cm plastic grow pots). 4 to 6 days in the slow seedling period, strengthen coverage, no ventilation, keep the daytime temperature 30 ° C, night 20 ° C, ground temperature 18 ~ 20 ° C.(large black 20 gallon nursery plant pots for sale)
If the bed soil nutrient is not enough(black plastic plant pots), enter the vigorous growth period, the temperature should be controlled, the daytime temperature is 25 °C, the nighttime is 15~16 °C, the daytime ground temperature is 16~17 °C, the nighttime is not lower than 13 °C, the sunny day is as much ventilation as possible(90mm plastic grow pots). In the continuous rainy days, artificial replenishment can be taken: water is sprayed once every 2 to 3 days depending on the weather conditions, and the bed soil is not exposed.
