摘要
[目的]了解不同物候期兰旗庙地区主要植物的变化规律.[方法]选取位于内蒙古自治区呼伦贝尔市西部中俄蒙三国交界处新巴尔虎右旗境内克鲁伦河流域的中温型草原群落作为研究对象,测定兰旗庙优质牧场、兰旗庙家庭牧场、兰旗庙公共牧场3个不同样地主要物种不同物候期的生理生态指标.[结果]在不同物候期草原群落主要物种的变化呈现一定的规律性,总体趋势为返青期各项指标相对稳定,经历了抽穗期和开花期的变化后,于果熟期又趋于稳定.[结论]研究结果为内蒙古自治区科学合理地管理草原提供了理论依据.
Abstract
[Objective] The aim was to study the variation law of main plants in Lanqimiao in different phenological periods.[Method] With temperate steppe community in Kelulun River Basin in Xinbaerhu Right Banner,Hultm Buir City,Inner Mongolia Autonomous Region as research object,physiological and ecological index of main species in different periods from Lanqimiao high quality pasture,Lanqimiao family pasture,Lanqimiao public pasture were determined.[Result] The variation of main species in different phenological periods showed a certain regularity,the general trend was:indicators are relatively stable in turning green period,then change in heading and flowering periods,finally tend to be stable in fruit ripening stage.[Conclusion] The study provides theoretical basis for scientific and rational management of grassland in Inner Mongolia Autonomous Region.
