Growing of miscantus giganteus planting material in the conditions of unstable moistening

Abstract

The paper covers some specific aspects of the planting material formation of the introduced crop of giant miscanthus in Ukraine. It was found out that in the zone of unstable moistening, the use of MaxiMarin absorbent resulted in a reliable growth of rhizome mass and more buds were formed on it. When planted with rhizome (mass is 20-30 g) and with the use of absorbent at the first planting term the mass growth of rhizome was larger at the end of vegetation as compared with the control, and depending on an absorbent kind it ranged from 78.4 g (the application of absorbent granules into the soil) to 433.6 g (combined application of absorbent granules and gel), more buds were formed on the rhizome – by 14.6-42.6 at the first planting term and by 8.4-42.5 at the second planting term as compared with the control. The increase of rhizome mass and the number of buds on it ensured the output growth of planting material – rhizomes, which depended on both the application of absorbent (granules and gel) and the mass of planted rhizomes and their planting terms. When planted with rhizome (mass is 60-90g) and with combined application of absorbent granules and gel more planting materials (large rhizomes) was received – by 2.1 times at the first planting term, - by 2.2 times at the second planting term, as compared with the control. More rhizomes - by 1.3 times - were received when planted with rhizome with 60-90 g mass than when rhizome mass was 20-30 g at both planting terms.
