In spring 2018 two new research fields were established having the following research goals:
- Field testing of the impact of PGRs to M.xgiganteus biomass parameters
- Monitoring of plant stress and it’s influence to biomass quality
- Technological production of miscanthus biomass for further energy testing
- Testing the phytotechnology with M.xgiganteus at the marginal land
Research field at Chomutov
On April 27, 2018 two plots was estabished at the research field of the Crop Research Institute, Chomutov. At the first plot rhizomes were planted according to the scheme used in 2017 (1 m x 1 m, 12 plants in the row). Half of the rhizomes were preliminary treated 12 hours before the planting by PGR Charkor with concentration 4 ml/l. Rhizomes treated by PGR were planted in every second row. The control plants were soaked into the clean water 12 hours before the planting and planted in each first row.
At the second research plot rhizomes were planted using the another scheme: 0,7 m x 0,5 m, 24 plants in row. That scheme is typical for establishing miscantus plantation and was used while establishing research fields in Ukraine. The order of rows with treated/untreated by PGR rhizomes was the same as in the first experiment.
All rhizomes planted at Chomutov were 2 years old and originally from the deposit site located at St.Elena, Croatia.
Research plots at Všebořice
On May 24th and 25th a research M.xgiganteus field was established at the former landfill located in Vseborice, Ústí nad Labem region (marginal land). The rhizomes used for planting were 10 years old and originally from the research plantation of The Silva Tarouca Research Institute of Landscape and Ornamental Gardening (RILOG), Pruhonice, Czech Republic.
The field was divided into the research plots, each of the plot was erected using the following scheme: 0,7 m x 0,5 m, 35 plants in the row, 6 rows; 210 rhizomes were planted in each unit.
Four of the research plots were established with rhizomes preliminary treated by PGRs. In two plots half of the planted rhizomes were treated by PGR Charkor with concentration 4 ml and time of exposure 12 hours. In two other plots half of the rhizomes were treated by PGR Stimpo with concentration 1 ml/l. Rhizomes treated by PGR were planted in every second row. The control plants were soaked 12 hours into the clean water before the planting and planted in each first row.
The rest of the plots established at the research field were planted using not treated rhizomes.
Soil samples were taken from both localities in Chomutov and Všebořice for further nutrient analyses, detection of contaminants and determination of soil microorganisms.
