【摘要】：【目的】研究新疆沙尔套山天然草地3个重要型草群营养物质的月动态变化与营养价值,对不同月季的3个重要草地型草群(针茅+芨芨草型、紫花鸢尾+禾草型、鸭茅+杂类草型)的营养成分(粗蛋白质、粗纤维、酸性洗涤纤维、中性洗涤纤维、粗灰分、钙、磷、总能)进行测定与分析和评价。【方法】采用国标法测定草群营养成分含量;运用SPSS 17.0、Duncan法及隶属函数分析法对数据进行处理。【结果】粗蛋白质、钙、磷、总能含量随着月份递增而下降,酸性洗涤纤维、中性洗涤纤维含量逐渐增高。营养价值评定按生长期综合排序为:5月6月7月8月9月10月11月。按不同草地型草群评定结果进行排序,其中5、6月的营养价值排序为:3型(针茅+芨芨草型)2型(紫花鸢尾+禾草型)1型(鸭茅+杂类草型);7、8、9、10、11月的营养价值排序均为:2型3型1型。【结论】新疆沙尔套山天然草地3个重要型草群在7、8月份具有较好的利用价值。
[Abstract]:[objective] to study the monthly dynamic changes and nutritional value of nutrients of three important grass groups in natural grassland of Shaertuoshan, Xinjiang, and to study the three important grassland types of different rose (Achnatherum splendens type, Iris oryzae type). Nutrients (crude protein, crude fiber, acid detergent fiber, neutral detergent fiber, crude ash, calcium, phosphorus) Total energy) was determined and analyzed and evaluated. [methods] the contents of nutrients in grass were determined by national standard method, and the data were processed by SPSS 17.0Duncan method and membership function analysis. [results] crude protein, calcium, phosphorus, The content of total energy decreased with the increase of month, and the content of acid detergent fiber and neutral detergent fiber increased gradually. The comprehensive order of nutritional value was: may, June, July, August, September, October, November. According to the evaluation results of different grassland types, In May and June, the order of nutritional value was in the order of: 3 (Achnatherum splendens type 2) (Iris purpurea) type 1 (Dactuca arundinacea L.), and the order of nutritional value in November was type 1, type 3, type 3. [conclusion] the order of nutritional value in Xinjiang is Shaer suite, Xinjiang. The three important types of grass groups in the natural grassland of the mountain have good utilization value in July and August.
