为探索经济、高效、环保的防治大豆胞囊线虫病的方法，以轮作过程中对大豆胞囊线虫毒杀效果明显的亚麻、大麻、蓖麻、万寿菊4种植物为试材，研究其根水提取物和根、叶乙醇提取物对大豆胞囊线虫卵孵化和线虫室内毒杀活性。结果表明：亚麻根提取物具有促进大豆胞囊线虫卵孵化的作用，对大豆胞囊线虫二龄幼虫毒性随着提取物浓度的增大而增强，亚麻根水提取物干粉∶水比例为1∶1和亚麻根乙醇提取物浓度为1．00‰和2．00‰时可以全部杀死大豆胞囊线虫。

For exploring the economic ,efficient and environmental control methods to soybean cyst nematodes , taking flax ,hemp ,castor and marigold as materials ,the toxic effect indoor of their roots ,water extract and roots ,leaves ethanol extract were studied on soybean cyst eggs hatch and nematodes .The results showed that extract of flax had a stimulatory function to the hatch of cysts and toxicity to the second instars of soybean cyst nematodes increased with the increasing of extracts concentration ,and it could kill all of soybean cyst nema-todes when the concentration of flax roots water extract was 1∶1 and the concentration of flan roots ethanol ex-tract was 1 .00‰ or 2 .00‰ .
