The two-year experiment was quartered in Blohorsk Street on two tram secch. Both m 60 meters and each is sown with a different type of plant.

At the Drinopol stops, the scientists will test carpet variants for stinn fix, and on the tram line near the U Katanu stops then for sunny.

The problem with white grass carpets is their low resistance to local conditions, the cost of gossip and irrigation. In the dry years, the slopes between the rails dried to a stand.

The average annual water consumption for active irrigation of 16 kilometers of tracks is more than 29 million liters of water with a cost of about 1.5 million crowns. If we wanted to have all-year-old green grass dogs at all times, it would mean ten and five times higher water consumption and costs less than six million crowns just for watering, explains Jan level, technical director of DPP, for testing new, durable grass carpets. dleit.

The aim of the project is to develop a new sowing mixture suitable for the extreme conditions of urban operation, including the recommended soil profile and the necessary cleaning.

During the experiment, the scientists will watch how the carpets react to the surrounding area. With this, special sensors will be placed on several cities of the track, which record the condition of the carpets non-stop. In order to be comparable, the scientists placed, in addition to experimental carpets, the tracks in the tracks of the street Evropsk.

The National Seed Bank also helped

Grasses and other species have been used in experimental green carpets from hardy plants that researchers have collected over the past 25 years at various extreme locations in the Rs and collected them as part of the National Plant Gene Pool Conservation Program. It serves for scientists as a reserve of native plants with unique heritage properties, explains Vojtch Holubec, national coordinator from the Genoa Bank of the Plant Production Research Institute in Prague..

Green carpets not only create a pleasant environment, but reduce heat and heat, trap rainwater and, compared to the asphalt clamp, absorb noise from tram traffic. They provide a variety of insects and small animals, contain up to 26 different plants, specifically 77 percent grass, 13 percent clover and 10 percent herbs.

The project with the duty to find the best combination of plants for grass carpets in Prague has been going on for a long time. In the first experiment, the researchers sown areas in the DPP Sdlit epy tram skids, Spoilov and at the metro depot in Hostivai, where they used the new seeding mixtures.
