| 摘 要： | 通过对大豆孢囊线虫病4号生理小种病土进行换土、施药、冷冻、研磨、加热等处理，研究影响大豆孢囊线虫病发生的的因素。经方差分析换土与其它处理有显著差异，施药、对照、冷冻、研磨处理间没有显著差异，但它们与加热处理有显著差异。所以我们认为鉴定用病土最好用刚开始稳定发病的病圃病土，而且使用次数不宜过多，如果是旧病圃，最好采取换土的方法提高孢囊侵染量。

| Abstract: | We studied stable toxicity and controlling technology of the diseased soil in identifying soybean cyst nematode with five methods, heating the diseased soil, exchanging the diseased soil with the diseased --free soil, frozen the diseased soil, appling nematocide and grinding the diseased soil. There was very significance variance between the method of exchange the diseased soil and the other methods. Soybean cyst nematode was sensitive to the heat treatment. In order to providing the quantity of soybean cyst nematode in the old-diseased soil, the best one was the method of exchanging the diseased soil with the diseased-free soil. |
