草地毒草狼毒发生及防治

Occurrence and Control of Stellera Chamaejasme L.in Grassland

在生态系统中,天然草地也是其中的重要组成部分。近年长期超载过牧、掠夺式经营等现象的出现,有毒有害植物的种类和数量也在不断增多,而且高度、生物量及生长速率等也呈现出明显的上升趋势。可食用牧草的营养和生存空间的数量和质量都在不断下降,导致草地严重退化。狼毒的出现,会导致草地进一步退化,使生态系统遭到严重破坏。该文针对草地毒草狼毒的成因和相应的防治对策进行探讨。

In the ecosystem,natural grassland is also an important component.In recent years,with the appearance of overgrazing and predatory management,the species and quantity of poisonous and harmful plants are increasing,and the height,biomass and growth rate are also increasing obviously.The quantity and quality of the nutrition and living space of the edible herbage are declining,which leads to the serious degeneration of the grassland.The emergence of stellera chamaejasme,will lead to further degradation of grassland,causing serious damage to the ecosystem.In this paper,the cause of formation of stellera chamaejasme L.and its control countermeasures were discussed.
