The results of studies of moisture content and wa ter holding capacity of the substrate in the cell cassettes “Plantek” 64F for the cultivation of containe r planting material. The moisture content of the substrate of cassette is taken at the output line of the Italian company “MosaGreenSrl” in RLSC, and then immersed in water for 48 hours is changed by the va riants of experiment in the range of 19.1–48.0%. The absolute humidity for different versions is 414.9–539.6%. With the high amount of moisture in the substrate air is virtually absent, wh at adversely affects the growth of plants. Adding more moisture will be run-off from substrate with nutrient depletion. The relative humidity in this case is 80%. The results of de-termining the absolute and relative humidity of the substrate in the cell depending on the weight of the cassette are presented. The mass range was significant – from 2.9 to 7.4 kg for “Plantek” 64F and from 3.4 to 9.7 kg for “Plantek” 35F. To visualize and understand the relationship of humidity of the substrate and mass of the built cassette diagrams was build. They are revealed that the optimal mass range for the cassettes “Plantek” 35F is in the range of from 5.0 to 6.5 kg, brand “Plantek” 64F – 4.0–5.5 kg. |
