江西野生牧草资源研究

Wild herbage resources in Jiangxi province

在全面调查的基础上,列出江西野生牧草名录,总结了江西省野生牧草的种类、分布及利用现状。江西共有野生牧草78科347属733种,区系成分复杂,生态类型多样,分布广泛,许多种类生物量大,营养价值较高,可直接饲用或作优势种质资源加以保护、保存。为进一步开发利用江西野生牧草资源提出建议。

Species distribution and utilization state of the wild herbage resource was investigated for the Jiangxi province The results showed that wild herbage resources are abundant in this province There are 78 families, 347 genera and 733 species (including subspecies and varieties) Like other subtropical areas in China, wild herbage resources in Jiangxi show the following described characteristics Gramineae is the major family and its feeding value is the highest, including genera such as Arthraxon, Arundinella, Digitaria, Echinochloa, Eragrostis, Ischaemum, Paspalum, Poa, and Setaria Species of Leguminosae are abundant with high nutrition value found in low proportions in swards The number of forbs is high, and they are widely distributed in various habitats An analysis of geographical and floristic aspects of wild herbage indicates that 69 genera (1988% of the total) have a cosmopolitan distribution, 176 genera (5072%) belong to the tropical and subtropical plant groups and 95 genera (2738%) belong to the temperate plant group The authors consider the wild forage herbage in Jiangxi Province shows typical change with the transition from temperate to tropical regions Ten herbage species are introduced, with their feeding value, nutrient content, distribution, and botanical characteristics described Some suggestions on how to explore and utilize the wild herbage resources of Jiangxi are given
