| 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（Triticum aestivum）、大麦（Hordeum vulgare）、燕麦（Avena 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，发病面积约200万hm2，在河南省18个省辖市中已有16个市有该病害发生，发病面积达170万hm2以上［2］，造成严重的经济损失。

| Abstract: | 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. |
