摘要
研究了在不同土壤类型条件下连种抗病品种和感病品种后，大豆孢囊线虫数量变化。结果表明：种植抗病品种无论在黑土或盐碱土地区，大豆植株根部寄生的和土壤中的孢囊数量均较少，且在年度之间或月份之间变化不大。种植感病品种在黑土或盐碱土条件下，大豆植株根部寄生的和土壤中的孢囊数量明显高于抗病品种，且随种植年限的增加而增加。
Resistant and susceptible varieties of soybean were planted continuously in different types of soil and the number of cyst nematode in the root system was counted. The results showed that there hardly was change of cyst number in resistant varieties between years or monthes in black soil and saline alkaline soil areas, but the cystnumber of susceptible varieties was much higher than that of resistant ones in black soil and Saline alkaline soil. Cyst number increased as the years of continuing planting increased.
