Технологическая карта выращивания leaf cabbage reflex в гидропонике

1. Seed Sowing

Длительность этапа:3 дня

* Substrate preparation. The substrate for cultivation may vary – organic (peat, coconut) or inert (mineral wool, expanded clay, perlite). Example substrate: a mixture of high-moor peat (5-15 mm) and agroperlite in a ratio of 4:1. The optimal pH level for the peat substrate is 5.8-6.2, and EC is 1.2 mS/cm.
* Preparing cups. Before filling, the cups are placed in special reusable plastic cassettes (cleaned and disinfected beforehand). After that, the substrate is poured over the cassette and distributed evenly over the entire surface. Cups should be filled level with the edge, and the substrate should not be compacted. The weight of a standard salad cup with properly prepared and placed substrate is 38-42 g.
* Sowing. Sow 3-5 seeds in each cup, covering with substrate or vermiculite.
* Watering and covering. After sowing, water the cassettes (the pot should weigh 48-50 g) and cover with nonwoven material or place in the sprouting chamber.

2. Care for Seedlings

Длительность этапа:21 день

* Transfer seedlings to the seedling department.
* Lighting. After arranging in the seedling department, begin to supplement seedlings with light. Light power is 100-130 W/m².
* Treatment with bioinsecticides. Treat seedlings with bioinsecticides to prevent aphid appearances when they have 2 true leaves.
* Watering. Watering and fertilizing is conducted mechanically or manually. Water seedlings three times a week with clean water and fertilize 2-3 times with standard solution.

3. Transplanting to a Permanent Place and Caring for Plants

Длительность этапа:55 дней

* Installation in a permanent place. When seedlings have formed 2-4 leaves and individual roots have reached through the mesh holes in the pot, they are placed in hydroponic modules. Ensure that the roots reach the film of the nutrient solution.
* Watering. The nutrient solution is changed every 2-3 weeks. The electrical conductivity of the solution in the autumn-winter period should be 2.0-2.2 mS/cm, in the spring-summer - 1.5-1.7 mS/cm depending on the lighting and temperature.
* Treatment with biopesticides. To protect plants from powdery mildew and other foliar infections, preventive spraying is recommended.

4. Harvesting

Длительность этапа:60 дней

* Harvesting. Harvesting of the 'Reflex' cabbage begins when the cabbage reaches commercial ripeness. It is best to harvest in the morning or evening hours to avoid overheating the cabbage. The harvested crop is carefully placed in containers to avoid damage. If the harvest is cut multiple times during the growing cycle, no more than 30% of the greenery should be harvested from one plant at a time.

5. Preparation for a New Cultivation Cycle

Длительность этапа:14 дней

* System cleaning. Remove residues of the previous substrate, roots, plants, and other organic materials.
* Disinfection. Fill the system with a 3% hydrogen peroxide solution and leave it for 1-2 hours. After disinfection, rinse the system three times with clean water to remove residues of disinfecting substances. Reusable cassettes need to be washed and disinfected in a hydrogen peroxide solution.
* Checking and adjusting heating and ventilation systems.
* Checking and maintaining the lighting systems.

6. Post-Harvest Storage

Длительность этапа:10 дней

Products are stored at a temperature of 0–5°C and relative humidity of the air 90–95% for up to 10 days; at a temperature of 4-5°C and relative humidity of air 90–95% – no more than 5 days.
