Abstract: The effects of three kinds of forage ramie [Boehmeria nivea （L.） Gaudich.] （Zhongsizhu No.1, Emu No.6 ramie, TG5） planted in 2018—2021 on water loss volume in sloping farmland were studied, and their biological yield and nutritional components were analyzed. The results showed that the average plant height of Zhongsizhu No. 1 was the highest in 4 years;the biological yield of Emu No.6 ramie was the highest and the corn was the least;the average water loss volume of Emu No.6 ramie was the least, and the corn was the most;in terms of stem leaf ratio, Emu No.6 ramie > Zhongsizhu No.1 > TG5; in terms of dry fresh ratio, Zhongsizhu No.1 > Emu No. 6 ramie> TG5. In 2008, the average soil loss of Emu No. 6 ramie was the least and corn was the most. In terms of crude fat, crude fiber, and crude protein, the ramie leaves were significantly better than those of ramie stems and corn. Forage ramie was an excellent feed crop on the hillside from the perspective of biological yield, conserving soil and water and nutrients.

Key words: ramie[Boehmeria nivea （L.） Gaudich.], corn, biological yield, nutritional components
