Disinfection and flushing of the greenhouse before planting.

The soil is sterilized by steaming.

The soil is loosened and corrugated pipes are laid to a depth of 25-30 cm.

Cover the ground with a film and steam is fed into the pipes.

Steaming is completed when a temperature of plus 70-90 degrees Celsius is reached in the soil at a depth of 30 cm.

After steaming, organic fertilizers are applied.

The soil is disinfected.

The soil is milled.

Watering seedlings in the ground.

I tie the plants with twine to a horizontal trellis.

Plants are tied at an angle, V-shaped.

All the time they do twisting around the twine and pinching.

Animation - the growth of a cucumber bush by twine.

At a height of 50 cm, the lateral shoots and flowers are removed from the plant.

At the next 50 cm, they pinch on the side shoots for one fruit.

The next 70cm is pinched into two fruits and two leaves.

The next 30cm is pinched into three fruits and three leaves.

The plant has risen above the trellis, it should be directed along the trellis.

The main stem is tied to a trellis and pinched.

The lateral shoots are directed downwards and pinched every 50 cm.

Lateral shoots are pinched into 1 leaf and one fruit.

Injured leaves and low-quality fruits are collected and exported.

Automatic devices maintain the desired temperature and humidity.
