摘要
对湖南农业大学苎麻(Boehmeria nivea)资源圃内120份饲用苎麻株高、叶尖、雌蕊色、叶形、叶色、叶缘锯齿、托叶等的植物学性状进行观测,并在其中选定20份生物产量较高的苎麻品种进行营养品种测定,对植物学和品质性状进行归类和分析。结果表明:不同苎麻资源植物学性状差异较大,按不同性状分类为,株高4类、叶尖4类、雌蕊色6类、叶形3类、叶色4类、叶缘锯齿4类、托叶4类。苎麻叶片的粗蛋白含量普遍较高,绝大多数品种的叶粗蛋白含量在19%以上,最高的达到了23.69%,且大部分品种纤维素含量在20%左右,适宜做牧草。
Botanical characters such as plant height,blade tip,pistil color,leaf shape,leaf color,serrated leaf margin,stipule of 120 forage ramie were evaluated in ramie germplasm repository of Hunan Agricultural University,and the nutritional composition of 20 ramie varieties with higher biological production were determined.The results showed that various ramie resources botany characters were different.According to the different characters,the classifications were that height was divided into four categories,leaf tip was divided into four categories,pistil color was divided into six categories,leaf shape was divided into three categories,leaf color was divided into four categories,serrated leaf margin was divided into four categories,stipules was divided into four categories.Crude protein content of leaf was generally high in ramie,the majority of varieties were over 19%,the highest crude protein content was 23.69%,and the cellulose content in majority of varieties was about 20%,they were suitable for the forage grass.
