高丹草品种品质性状与产量的相关分析

研究通过对从外省区引入新疆的几个高丹草品种品质性状和鲜生物产量的相关分析表明:粗脂肪、粗纤维、中性洗涤纤维、酸性洗涤纤维与鲜生物产量呈一定的正相关,粗蛋白、粗脂肪与干物质含量呈一定的正相关。综合分析表明,甘露2号和先锋两个高丹草品种相对其他品种具有明显优势,其中甘露2号鲜生物产量76300 kg/hm2,干生物产量26500 kg/hm2,粗蛋白含量8.77%,粗脂肪含量1.57%,粗纤维含量30.53%;先锋鲜生物产量74 766.67 kg/hm2,干生物产量25395.43 kg/hm2,粗蛋白含量8.78%,粗脂肪含量1.42%,粗纤维含量33.88%。

Correlation Analysis on Quality Trails and Yield on Gaodangrass Varieties

The studies on correlation analysis between forage nutritive quality trails and the biological yield indicated that there is a positive correlation tends among main nutrient characters and fresh biological yield,such as ether extract,crude fiber,neutral detergent fiber and acid detergent fiber.Secondly there is also positive tends among crude fiber,crude protein and dry matter contents.The result showed that ganlu2 and pioneer have obvious predominance to farming of Xinjiang respectively.Among them the content of the Ganlu2 are fresh yield (76 300 kg/hm2),dry yield(26 500 kg/hm2),crude protein(8.77%),content of crude fat(1.57%),crude fiber(30.53%).Among them the content of the pioneer are fresh yield(74 766.67 kg/hm2),dry yield(25 395.43 kg/hm2),crude protein(8.78%),content of crude fat(1.42%),crude fiber(33.88%).
