【摘要】 植物寄生线虫是导致马铃薯减产和影响马铃薯品质的原因之一,但目前黑龙江省尚未开展相关研究。自2012年以来,在黑龙江省共调查了14个县(市)的马铃薯种薯田,采集土壤样品107份,初步鉴定出植物寄生线虫8个属,其中针属线虫(Paratylenchus sp.)和螺旋属线虫(Helicotylenchus sp.)为黑龙江省马铃薯种薯田植物寄生线虫的优势种群,并分析了其地理分布特点。在黑龙江省发现短体属线虫,其属于重要农业生产的植物寄生虫。更多还原

However,there is no any comprehensive study concerning plant parasitic nematode on potato yet. We collected 107 soil samples from14 seed potato production fields in Heilongjiang province since 2012, and identified 8 genera plant parasitic nematodes, of which, Paratylenchus sp. and Helicotylenchus sp.were dominant species of plant parasitic nematodes distributed in seed potato production fields of Heilongjiang Province. Geographical distribution of plant parasitic nematode was analyzed.Paratylenchus sp. was found in Heilongjiang Province which was economically species of parasitic nematodes oncrops.更多还原
