The control effects and application methods of Pleurotus ostreatus on the peanut root knot nematode disease, Meloidogyne arenaria, were systematically studied in the greenhouse.

通过盆栽试验研究了杀线虫担子菌-粗皮侧耳（Pleurotus ostreatus）对花生根结线虫病的防治作用及施用技术。

The results showed that on mobile sand, Hedysarum scoparium had the widest niche breadth, followed by Artemisia arenaria.

结果表明：在流动沙地上花棒的生态位宽度最大，其次是沙蒿；

By the method of whole digging sampling, the ecological characteristics of roots of Artemisa arenaria were studied in different types sands land in arid desert area.

用全挖取样法研究了干旱荒漠区不同类型沙地上沙蒿种群的根系生态特征。

In the range of 0~ 40 cm soil layer, in different type sands land 75% roots biomass of Artemisa arenaria were existed.

从根系分布深度看，在不同类型沙地上，沙蒿根系生物量集中分布在0~40cm土层中，占75%以上；

With wide host range, extensive geographical distribution and good adaptability, M. arenaria had high risk to agriculture and forestry, and was of great quarantine importance.

花生根结线虫的寄主范围宽，地理分布广，适应性强，对农林生产的危险性极大，而且具有很大的检疫重要性。
