| 摘 要： | 为了查明黑河地区大豆胞囊线虫的分布,对2010和2011年采集的黑河地区96份大豆田土样进行调查,研究了黑河地区大豆胞囊线虫的种群密度。结果表明:黑河地区采集的土样均发现大豆胞囊线虫,且其胞囊密度分布不均匀。将黑河地区各点连续2a采集得到每100g风干土中胞囊数量分为5个区段:胞囊密度为0～50个的占13.79%,胞囊密度为50～100个的占37.93%,胞囊密度为100～150个的占17.24%,胞囊密度为150～200个的占27.57%,胞囊密度超过200个的占3.45%。

| Abstract: | In order to study the distribution of soybean cyst nematode,96 soybean cyst nematode(SCN)soil samples were collected from 35 cities and counties in Heihe in 2010 and 2011,the population density of SCN of Heihe area was studied.The results showed that SCN was detected in all tested soil samples,and the density was uneven distribution.The population density of SCN cysts were divided into five sections 0~50 per 100 g dry soil accounted for 13.79%,50~100 per 100 g dry soil accounted for 37.93%,100~150 per 100 g dry soil accounted for 17.24%,150~200 per 100 g dry soil accounted for 27.57%,more than 200 per 100 g dry soil accounted for 3.45%. |
