Мiscanthus

Miscanthus is a C4 perennial herb native to Southeast Asia. It is a very efficient crop that can produce up to 25 tons of dry matter per year in Central Europe after a yard growing period. It can be harvested annually during the growing period of up to twenty years. The use of herbicides is necessary only at the seedling stage. Its biomass can be used for a wide range of utilization routes, including incineration, conversion to bioethanol, production of construction materials and basic chemicals.

Propagation material – Rhizomes

Miscanthus Giganteus is currently the most widely cultivated genotype. Being a triploid interspecific hybrid, this genotype does not produce fertile seeds and must be propagated by rhizomes. Compared to seed propagation, this method is very time-consuming and quite expensive.

Planting-Rizom

Miscanthus rhizomes are planted using a rhizome planter, which can be compared to a potato planter.

Miscanthus is a perennial crop that can be harvested annually after a two-year growing period for a total growing period of up to 20 years. Chemical or mechanical weeding is necessary only in the first two years. There are no known pests or diseases that affect miscanthus. In addition, it requires only a small amount of fertilizer. It is recommended to fertilize the crop with the amount of nutrients extracted through the harvested biomass.

Harvest

Miscanthus can be collected in the form of rolls or bales. In Central Europe, due to cold winters, biomass has a low water content of around 15 percent at harvest. Therefore, harvesting is carried out with a self-propelled forage harvester, as shown in the picture.

Harvest-Bales

If the biomass is too wet, the entire crop is laid out in a roll and then pressed.

Efficiency

Miscanthus is a low-input crop with high water, land use and energy efficiency. Studies have shown that miscanthus is capable of producing a net energy yield of up to 590 G per hectare per year. In addition, it returns nutrients from the above-ground biomass back to the rhizomes in autumn, i.e. before harvest. The rhizomes serve as storage organs for re-sprouting the following spring. For this reason, miscanthus needs only small amounts of fertilizer.
