| 摘 要： | 通过连续观测10年(1987-1996)环青海湖天然草场优势牧草以及气象要素,分析了气候变化对青海湖天然草场牧草营养的影响.研究结果表明:1)青海湖天然草场优势牧草单位面积干物质(DM)、粗蛋白(CP)、粗脂肪(EE)、无氮浸出物(NFE)、粗纤维(CF)的生产力呈下降趋势;2)优势牧草群组的粗蛋白、粗脂肪、无氮浸出物...

| Abstract: | The impacts of different meteorological factors on the forage nutrient material and grassland nutrient type were analyzed through a continuous 10 years(between 1987 and 1996) observation on five dominant forage species.The results showed that crude protein(CP),crude ether extract(EF),nitrogen-free extract(NFE) and crude fiber(CF) have significant relations with precipitation in April,days of precipitation above 1mm and underground 10cm soil temperature during the main growing months(From May to August) at t... |
