Технологическая карта выращивания sunflower в минеральной вате

1. Seed Sowing

Длительность этапа:3 дня

* Tray Preparation. Flat containers or trays with low sides are suitable for forcing. Mineral wool is laid in trays and well moistened with water or nutrient solution.
* Seed Soaking. To accelerate germination, seeds are soaked in warm water for 12 hours. Only clean, untreated seeds should be used. Since sunflower seeds are highly susceptible to fungal diseases, they are treated with a hydrogen peroxide solution or a 1% potassium permanganate solution for 20 minutes.
* Sowing. Seeds are evenly distributed across the surface of the substrate, pressing them slightly for better contact. After sowing, seeds are moistened from a sprayer, covered with film, and pressed down with another tray. A weight is placed on top of the trays for better contact between seeds and substrate.

2. Microgreens Growth

Длительность этапа:7 дней

* Lighting. With the emergence of friendly seedlings, the film is removed from the trays and artificial lighting is set up. Lighting power is 80-90 W/m².
* Watering. Microgreens are watered as the substrate dries, using clean water or nutrient solution. To form beautiful microgreens, it is important to timely remove the husk from sunflower seedlings. If it is difficult to remove the husk, the seedlings are sprayed on top with water and covered with film for 5-10 minutes. After this, it will be easier to remove the husk from the seedlings.

3. Microgreens Harvesting

Длительность этапа:1 день

* Cutting. Harvesting sunflower microgreens is done when the plants reach a height of 5-7 cm and have their first true leaves. The harvest is collected by cutting the plants at the base. It is important to conduct the harvest in the morning when the plants are freshest. After harvesting, the microgreens should be cooled to 4°C to maintain freshness.

4. Preparation for the Next Growing Cycle

Длительность этапа:1 день

* Cleaning. Removal of residues from the previous substrate, roots, plants, and other organic materials.
* Disinfection. Treatment of surfaces, watering containers, and work tools with a hydrogen peroxide solution (3%).

5. Storage after Harvest

Длительность этапа:3 дня

Store greens after harvest for no more than 2-3 days at a temperature of 0-1°C and relative humidity of 90-95%.
