我省的草山、草坡地据初步调查约有3400余万亩,都属于亚热带与北热带的半天然草场,次生植被的结构随海拔高度、坡度与坡向不同而有差异,十分复杂。境内,气候温和,雨量充沛,对牧草生长极为有利;而且夏、冬季比温带有更多的日照时间供牧草生长发育。然而,我省山地土壤都是酸性红壤或黄壤,有机质少,普遍缺乏钙、磷等植物必须的营养元素,土壤较贫瘠。因此,野生植物群落中适宜于牲畜采食的牧草种类贫乏,特别是豆科牧草更为稀少。山地草场植被中芒草类与芒萁草占了相当大的比重。
According to the preliminary investigation, there are about 3400 mu of grassy and grassland slopes in our province, all belong to the semi-natural grassland of the subtropical and the northern tropical. The structure of the secondary vegetation varies greatly with altitude, slope and aspect, and is very complicated. The territory, the mild climate, abundant rainfall, forage grass growth is extremely beneficial; and summer, winter than the temperate zone with more sunshine hours for the growth and development of grass. However, mountainous soils in our province are acidic red or yellow soils, with little organic matter, generally lacking nutrients necessary for plants such as calcium and phosphorus, and the soil is relatively barren. Therefore, the species of wild grasses suitable for livestock feeding are poor, especially the legumes. Mountain meadow vegetation Miscanthus and Mangosteen accounted for a considerable proportion.
