紫花苜蓿的细胞壁含有木质素、纤维素、半纤维素,纤维束缚蛋白质及纤维束缚矿物质等,这些物质营养价值的高低取决于它们木质化的程度(Bartonet al.,1977)。木质素中的束缚多糖的结构类型及其含量的多少对紫花苜蓿的消化率有很大影响,而木质素及其它各纤维成份的含量则受刈割次数的
The cell wall of alfalfa contains lignin, cellulose, hemicellulose, fiber-bound proteins and fiber-bound minerals. The nutritional value of these materials depends on their degree of lignification (Barton et al., 1977). Lignin in the structure of the type and content of bound sugar has a significant impact on the digestibility of alfalfa, while the lignin and other fiber content by cutting the number of
