摘要
从湖南农业大学苎麻资源圃内筛选出生长势强、发蔸力好的30份优异饲用苎麻Boehmeria nivea种质资源作为试验材料,收获头麻后,在株高50-60 cm时进行刈割,每次刈割测定生物学产量和粗蛋白含量。综合生物学产量与粗蛋白含量结果,初步筛选出适宜饲用的种质为巫山线麻,收获头麻后,6次生物学总产量达22 215 kg/hm^2,粗蛋白含量为25.43%。这为解决南方高蛋白饲料缺乏提供了可能,且苎麻生物学产量高,在南方适应性强,是一种优良的高蛋白牧草,开发潜力很大。
The mowing test was conducted on 30 excellent Ramie （Boehmeria nivea ） forage germplasm resources in Ramie resources nursery at the height of 50-60 cm, and the biological output and crude protein content were determined. The results showed that suitable forage germplasm lines was Wu Shan Xian Ma. After the first harvest, the total biological output of 6 times mowing was 22 215 kg/hm^2 , crude protein content was 25.43%. So it could resolve the problem of the lack of high-protein feed in southern. Ramie was excellent high protein forage, and it has great development potential with its high biological yield and high adaptability in the South.
