中文摘要：
以番茄根围土壤为试材,采用在种植诱集蔬菜（白菜）后的土壤和用杀线虫剂处理土壤种植番茄,来研究番茄生长期间根围土壤不同土层根结线虫2龄幼虫的种群动态变化。结果表明：根结线虫J2种群数量随着土层的加深而减少。诱集蔬菜明显降低0～10cm土层J2种群数量,施药处理能降低10～30cm土层J2种群数量,而施药处理和诱集蔬菜处理对30～40cm土层J2种群数量没有影响。
英文摘要：
Taking tomato rhizosphere soil as materials,treated with planting trapping vegetable and nematicide treatment,population dynamics of the 2nd instar larvae of Meloidogyne spp.around them were detected.The results showed that the number of Meloidogyne spp.J2 decreased with increasing of soil depth.Trapping vegetable could significantly decrease J2 in 0-10cm soil depth.Nematicide treatment could decrease J2 in 10-30cm soil depth.Both trapping vegetable and nematicide treatment had no significant effect on J2 in 30-40cm soil depth.
