| 摘 要： | 为构建种养结合模式，就地消纳养殖沼液，明确其对大麦饲用价值构成的影响，在江苏沿海地区进行了沼液还田模式下苏啤8号大麦主要性状和饲用指标间的相关性研究。结果表明，苏啤8号大麦株高与生物量呈显著正相关，且株高、茎叶比和干物质含量对生物量的影响达到88．0％；水分含量、总淀粉含量、千粒重和小区籽实产量与籽粒蛋白质含量呈显著或极显著正相关（或负相关），影响达到了95．9％；苏啤8号大麦植株的饲用品质指标分析中，粗灰分、粗纤维、中性洗涤纤维和酸性洗涤纤维含量对粗蛋白含量的线性相关程度密切，影响达到了70．0％。研究提示，沼液还田模式下苏啤8号大麦饲用潜力巨大，生产中可利用株高、产量等表观指标估测饲用价值，从而指导生产管理。

| Abstract: | In order to construct the combination model of farming and breeding, to utilize the biogas-slurry produced by livestock breeding industry, and to determine the effect of this model on feeding quality composition of barley, a study on correlation between main traits and feeding quality indexes of the barley variety of Supi No. 8 under biogas-slurry returning to field mode was carried out in .liangsu coastal area. The results showed that the height of Supi No. 8 was significantly positively correlated with the biomass, and effects of height, ratio of stem and leaf as well as dry matter content on biomass reached up to 88.0%; the moisture content, total starch content, thousand-grain weight, and plot grain yield were significantly or extremely significantly positively （or negatively） correlated with grain protein content, and the impact reached up to 95.9%; in the whole-plant feeding quality analysis of Supi No. 8, the content of crude ash, crude fiber, neutral washing fiber and acidic washing fiber were closely related to the linear relationship of the crude protein content, and the effect reached 70.0%. This study indicated that the barley variety of Supi No. 8 had a great feeding potential under biogas-slurry returning to field model, and the apparent indexes such as plant height and yield could be used to estimate the feeding value and guide the production management. |
