Eggplant cultivation techniques - plug cultivation
August 15, 2024
The cultivation of strong seedlings by growers when growing eggplant is the basis for obtaining early maturing and high yield. Compared with conventional seedlings, eggplant plug seedlings have the advantages of strong seedlings, less disease, shorter time, land conservation, high uniformity, and convenient transportation, and are welcomed by vegetable farmers. The specific method is described as follows:
The eggplant seedlings in the greenhouse are 60 to 70 days old. Usually, 50 or 72-point seedling trays are selected. The ratio of the matrix is grass charcoal: chicken manure: cow manure 2:1:1:1, or 1:0.5:0.5, plus a small amount of slow-release fertilizer, the grass charcoal need to be crushed after screening. Put the prepared matrix into the tray and set it aside. The matrix must not be overfilled to prevent water from flowing out when watering.
Put the seeds in warm water of 50°C～55°C, soak them in the mixture for 20 hours at room temperature, remove the seeds and rinse them with clean water, filter the water, and reserve the water after use.
Before sowing, soak the wells with a hole in the hole in the bottom of the wells. Precipitate the seeds in the hole. Put the seeds into the tray, 1 to 2 capsules per hole, and then cover with a layer of substrate, level with the plate, cover the film, Insulation moisture. Maintain 25°C to 30°C during emergence. When the emergence of more than 50% when the film opened, the temperature should be controlled at 22 °C ~ 25 °C.
Plug seedlings should pay attention to timely replenishment, generally when the substrate surface is whitish, it needs replenishment. At the same time, according to the content of substrate nutrients and growing seedlings, combined with replenishment spraying 0.2% potassium dihydrogen phosphate + 0.2% urea mixed solution for foliar supplementation . The control of pests and diseases is the same as conventional nursery. When the seedlings 5 to 7 true leaves, plant height of about 15 cm, the root system into a pot and spray white roots can be planted. When planting, the seedling plate is transported directly to Daejeon, and the seedlings are pulled out by hand and implanted in the field.
