摘要： 由于大豆孢囊线虫病的危害，山西省大豆产量低而不稳。为了查清病情，由省农科院植保所和省农牧厅植保站主持，各地、市植保站参加，组成山西省大豆孢囊线虫病调查协作组，于1984-1986年先后调查了111个县、区的1681个乡、镇，共取土样2602个，基本查清了大豆孢囊线虫病的发生分布，为害程度和寄主范围。此病已在全省普遍发生，多数为轻病田，少数为重病田。寄主植物多达13种，其中以豆类为主。根据调查结果已编写出《山西省大豆孢囊线虫病发生分布，为害程度和寄主范围名录》，并绘制出《山西省大豆孢囊线虫病分布图》，为科研和防治工作提供了参考和依据。

Abstract: The bean yield was low and insrable because of damage caused by cyst nematode of soybean in Shanxi.In order to lay a foundation for scientific research and control,a cooperation group of investigation had established in 1984.This disease was investigated in whole provincial region with township by the cooperation group from 1984 to 1986.We investigated totally 111 counties and 1681 townships,at the same time,collected 2602 soil samples.The geographic distribution,demage extent and host range of cyst nematode of soybean have been found out basically.The 111 counties and 1573 townships were discovered areas.There were 2303 soil samples which contained the cysts.The result Shows that soybean cyst nematodiasis has been occurring anywhere in Shanxi.Most of areas belong to the slight disease regions,but exist many serious disease fields.We found out 13 species host plants in Shanxi.It was obvious that bean crops were host of this nematode.The Shanxi name list for geographic distribution,damage extent and host range of cyst nematodiasis of soybean had been compiled according to the investigation result,and the scattering chart had been drawed up too.This not only afford a experience of organization and leadship for future,but also provide a referntial material for scientific research and control In whole provincial region investigating clearness with township is the first time at home.
