摘要: 研究了2018—2021年种植3种饲料苎麻[Boehmeria nivea (L.) Gaudich.](中饲苎1号、鄂牧6号苎麻、TG5)对坡耕地水流失量的影响,并对其生物产量及营养成分进行了分析。结果表明,综合4年的平均值,中饲苎1号株高最高;生物产量鄂牧6号苎麻最高,玉米最低;平均水流失量鄂牧6号苎麻最少,玉米最多;在茎叶比方面,鄂牧6号苎麻>中饲苎1号> TG5;在干鲜比方面,中饲苎1号>鄂牧6号苎麻> TG5。2008年平均土流失量鄂牧6号苎麻最少,玉米最多。在粗脂肪、粗纤维、粗蛋白方面,苎麻叶的表现明显优于苎麻茎和玉米。饲用苎麻从生物产量、固水、营养物质来看,是优良的山坡地饲料作物。

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
