摘要对比中蒙8嘎查内和嘎查间植物营养特性,结果表明,除内蒙古东乌旗满都镇白音布日德嘎查外内蒙古的其他嘎查调查区域内原生植物叶绿素、营养成分含量较低,葱属植物和一年生植物营养成分含量较高;蒙古四个嘎查调查区域内原生植物叶绿素、营养成分含量明显高于一年生植物;8嘎查调查范围内全钾与其他各营养成分间差异显著,各嘎查钾含量较丰富,氮、磷、碳水化合物含量较短缺;这可能与年降雨量、放牧方式和草原植物退化有关。中蒙8个嘎查间植物营养成分比较结果表明,08-NMG-A-4植物可溶性糖含量为最高,与其他嘎查间存在极显著差异;07-NMG-B-108-MG-A-308-NMG-A-4植物叶绿素总含量、全氮、全磷、钾含量为较高,氮钾含量在07-NMG-B-108-MG-A-308-NMG-A-4嘎查间差异不显著外,其他嘎查间差异达到显著水平;叶绿素总含量、全磷在07-NMG-B-108-NMG-A-4嘎查间差异不显著外,与其他嘎查间达到显著或极显著差异水平。内蒙古东乌旗满都镇白音布日德嘎查植物营养成分含量较高的可能原因是主要与该地区草地类型有关,草甸草原土壤较湿润,土壤营养较好。因植物和土壤是生态系统中相互作用的两个主要因素,导致地上植物营养较丰富;07-NMG-B-1嘎查由于定居放牧,在小范围内家畜的排泄物(粪、尿)积累的较多,可能导致植物营养成分有所提升。本论文通过分析中蒙8个嘎查植物营养特性,研究放牧方式如何影响植物营养成分,放牧方式与植物营养间存在何种关系,为了平衡蒙古高原草原植物营养含量,提供科学的依据。

Abstract: Compare of nutrition characteristics among the eight villages, result showed that chlorophyl and nutrition contents in 08-NMG-A-4 are the highest, annual plant nutrition content in other villages is higher. Native plant nutrition ingredient is higher than annual plant in the four villages of Mongolia.Kalium is plentiful among the eight villages, it is a significant difference among the eight villages. Content of nitrogen, phosphorus and carbohydrate is shortage, it related to grazing, precipitation and grassland degeneration. Soluble sugar content is the highest in 08-NMG-A-4,it is a significant difference between other villages. Content of plant chlorophyll, nitrogen,phosphorus and kalium in the 07-NMG-B-1,08-MG-A-3 and 08-NMG-A-4 is higher, it is not significant difference between 07-NMG-B-1 ,08-NMG-A-4 and other villages. Plant nutrition content in 08-NMG-A-4 is higher, it mainly related to soil is more moisture and soil nutrition is better. Plant and soil are dominant factors in ecosystems.Because settled grazing in 07-NMG-B-1,livestock’s excretion is more and lead to plant nutrition is enhanced. Study on plant nutrition among the eight villages and effect of nutrition under different grazing, relation of grazing and nutrition, provide scientific basis for plant nutrition in Mongolian plateau.
