黑龙江省西部草原类型及草地蝗虫防治研究(英文)

Study on Grassland Types in Western Heilongjiang Province and Control of Grasshoppers

黑龙江省西部草原基本上属于较为中生的草甸草原,草的种类达103种以上,其分布最大的是羊草草甸草原、羊草和杂类草原。羊草、野古草、中华隐子草、贝加尔针茅、苔草、小叶樟、柳叶蒿、乌拉草、三棱草等为主要优势和亚优势种。危害草原的草地蝗虫常见种类约有17种,优势种有8种。针对黑龙江省西部草原、植被、草地蝗虫种类等的特点,提出了该地区草地蝗虫综合治理措施。

The grassland in western Heilongiiang basically belongs to mesophytic meadow grassland with more than 103 species of grasses, while Leymus chinensis meadow grassland and L. chinensis herbage steppe have the largest distribution. L. chinensis, ArundineUa hirta （ Thunb. ） C. Tanaka, Gleistogenes chinensis （ Max- im. ） Keng, Stipa baicalensis Roshev, Carex tristachya, Deyeuxia langsdorffii （Link） Kunth, Artemisia integrifolia, Carex meyeriana and Cyperus rotundus are the main dominant and subdominant species. There are about 17 common species of grasshoppers causing damage on grassland, while eight of them are dominant spe- cies. According to the characters of grassland, vegetation and the species of grasshoppers, the paper has raised the integrated control measures for grasshoppers in western Heilongjiang.
