查询词典 Larix

Through the preliminary study on the management of the population of Athyrium multidentatum, we found that the community of artificial Larix gmelinii forest has a high value of usage. Planting the population of Athyrium multidentatum may make us to improve the level of intensive management, and through the test this method is available. The population of the spacing in the row of forty cm in the community of Betulla platyphylla forest and the population of the spacing in the row of eighty cm in the community of artificial Larix gmelinii forest have the largest hight, leafstalk diameter and less herb coverage. The foodstuff technology of ferns is backward and the products are less, so we must improve the study on the usage of forest ferns.
