摘要：

小麦禾谷孢囊线虫(Cereal Cyst Nematode,CCN)病是一种世界性病害,主要为害小麦(Tritic-um aestivum)、大麦(Hordeum vulgare)、燕麦(Ave-na saliva)、黑麦(Secale cereale)等禾本科植物[1],近年来该病害在全世界发展迅速并造成严重经济损失,在我国,已证实该线虫在北京、山东、河南、河北、安徽等16个省、市、自治区均有分布,发病面积

摘要：

The impacts of soil nutrient elements on cereal cyst nematode were studied.The results showed that the mortality rate of secondary stage juvenile(J2)treated with N or P at different concentrations as well as 6 fold concentration of K was obviously higher than that of control,while the other three elements showed no difference.With respect to the minor elements,the mortality rate was higher than control when treated with Mn at a concentration over 5 fold and the mortality raised by the increase of concentration.Each Cu treatment increased the mortality significantly as compared with the control.
