Planting and Management Technology of eggplant in greenhouse

First, soil preparation and fertilization, select fertile, loose, breathable land, and then flatten it and apply basic fertilizer; the second is to build a shed and two flat beds to build a greenhouse with a height of about 4 meters; the third is reasonable water and fertilizer and temperature control; the fourth is to remove leaves, eggplant seedlings grow to about 30 cm to remove the terminal bud, and then produce the lateral branch terminal bud after forming. Finally, we can do a good job in pest prevention and control.

Eggplant should do the following work well before planting:

1. Stuffy shed disinfection

Every cubic meter of greenhouse or greenhouse, use 4 grams of sulfur powder, add 0.1 grams of 80% dichlorvos and 8 grams of sawing eggplant growth foam, mix well and ignite, seal the greenhouse or greenhouse for 24 hours, and then open the mouth to put a strong wind.

two。 Soil preparation and fertilization

Apply 5000 kg of high-quality farm manure per mu, rake the soil evenly, and open a planting ditch 10-15 cm deep according to 55 cm row spacing. Apply 20 kg of diammonium phosphate per mu, 30 kg of potassium sulfate, and cover 5 cm of soil after fertilization (avoid dripping waterline).

3. Colonization

Put the seedlings at a distance of 25-30 cm (pay attention to avoid slow seedling caused by broken seedling), then pour enough planting water in the ditch and cultivate the soil to form ridges after infiltration. The next day, the plastic film was covered with 1.0-1.2 meters wide plastic film, buckled two ridges at a time and stretched to the same length as the ridge, then cut a longitudinal mouth in each plant position with a blade, drew the seedlings out of the mouth, and finally tightened the plastic film and sealed the planting mouth with soil pressure.

Of course, the situation is different in each region, so there may be differences in dosage and time. The details should be determined according to the actual situation and must not be copied blindly.
