| 摘 要： | 2009年呼伦贝尔市牧草生长季前期温高、少雨,牧草返青期推迟,正常生长发育受阻。需水关键期雨水充沛,长势较好。现蕾至开花期温低、光弱,制约了牧草营养成分的积累。后期气候与牧草生理需求相适宜,籽粒灌浆成熟率高。大风日数减少,削弱沙丘移动覆盖草场发展趋势,对维持草原生态系统平衡十分有利。综合分析牧草产量、品质属平年年景。

| Abstract: | In Hulunbeier in 2009,returning green stage of forage grasses was delayed,which retarded their normal growth,because of higher temperature and less rainfall in the early vegetative season.The forage grasses grew well due to abundant rain in critical period of rain requirement.The low temperature and weak light from flower bud emergence to flowering stage restricted the accumulation of nutrients in forage grasses.The later climate could meet the physiological needs of forage grasses,and maturation rate of grain filling was high.The reduction in the number of gale days delayed coverage of grassland by dune,which was beneficial for maintaining the balance of grassland ecosystems.The paper also analyzes forage yield comprehensively and proposes that their quality should be similar to the harvest pattern of common years. |
