Study On The Biological Character Of The Introduction Of Resources M. Giganteu

Miscanthus is a tall and native perennial C4 herb plant in China, but also a good energy plant, so it has an important potential for development. Through the study of biological traits of Miscanthus resources in different years, it is found that:three times the size of M.Giganteu plants reached up to 2.3m in 2013 and the average height was 192.3cm. During the whole growth period, the total number of leaves could be up to 21 leaves. The average number of tillers in the per hole was 78 and it could reach up to a maximum 121; Miscanthus plants could reach up to 2.1m in 2014 with the average height of 197.7cm. Leaves in the whole growth period could reach up to 24. The average tillers per hole were 53 and it could reach up to a maximum of 70. The hole diameter could be up to 41.33cm and the number of stems could reach up to a maximum of 41.5. Miscanthus dry matter accumulation is in line with the exponential growth function, but the growth center of the growth period is different. The early period gives the first place to leaf dry weight accumulation, during the reproductive mid-term, dry matter accumulations of leaves and stalks are equally important while the later period is based on stalk dry matter accumulation.Comparied diploid MSinensis and tetraploid M. sacchariflors, triploid M.Giganteu is better than those on various growth in dicators.Triploid M.Giganteu not naturally grow in cold winter of Yanbian.Triploids M.Giganteu are not fruit, cluster, and can be used by anon-proliferation of bioenergy plant resources. Diploid M.Sinensisthat is fruit, and tetraploid M.Sacchariflorus that is channeling root can not grow in the surrounding farmland, but can only be Aut ogenous use in wilderness, because of their diffuse nature andweed property。...
