摘要
瑞香狼毒是我国天然草地重要的有毒植物之一,在东北、华北、西北及西南的草甸草地、典型草地、高寒草地以及荒漠草地都有不同程度地分布。多年来,由于超载过牧,天然草地严重退化,导致瑞香狼毒等毒害草在过度放牧的退化草地大量滋生和蔓延,成为优势种群。不仅造成草地生产力下降,影响草地畜牧业的可持续发展和生态安全,而且牲畜采食后引起急性中毒,造成重大经济损失,近年被列为我国天然草地重点防控的毒害草。论文综述了近年来我国瑞香狼毒生物学特性与分布、化学成分,毒性,化感作用,危害与防控以及综合利用等方面的研究进展,并提出现阶段对瑞香狼毒的防控,应在充分认识瑞香狼毒在天然草地生态群落中的生态作用,切忌盲目地铲除或灭除,把瑞香狼毒作为天然草地可利用的植物资源合理利用,发挥瑞香狼毒本身的价值。
Stellera chamaejasme is one of the important poisonous plants in our country＇s natural grasslands,and distribute in meadows,typical grasslands,alpine meadows and desert grasslands in the northeast,north,northwest and southwest of China at different levels.For many years,natural grassands have suffered severe degeneration due to overgrazing and poisonous plants such as Stellrachamaejasmehave been widespread and become dominant populations in overgrazed and degenerated grasslands.This causes the reduction of grasslands＇ productivity and thus affects the sustainable development and ecological security of the grazing industry.The poisonous plants may cause acute poisoning if eaten by the livetock and then make great economic losses.Stellera chamaejasme has been listed as the focus of prevention and control of natural grassland poisonous grass.This article reviewed the domestic progress of research in biological characteristics and distribution,chemical composition,toxicity,allelopathy,hazards,prevention and control and utilization of Stellera chamaejasme.It proposed the present prevention and control of Stellra chamaejasme should be based on the acknowledgement of the plant＇s ecological status and avoid blind eliminating and make best use of it as plant resources in the natural grasslands,so the value of Stellra chamaejasme can be developed.
