Abstract:

Taking 19 plants as experimental material，this paper studies the effects of different accompanying plants on controlling tomato root-knot nematode and promoting tomato growth．The results of preliminary and secondary screening indicated that 4 plants including rape，tillering onion，mint and fennel accompanying tomato could significantly reduce the number of tomato root-knot and its root-knot index．The relative control effect was 58.7%-82.8%．They had no remarkable inhibitory effect on tomato growth．Thus，they can be used as effective accompanying plants to reduce tomato root-knot nematode disease．

Key words: Accompanying plant, Tomato, Root-knot nematode disease

摘要：

以19 种植物为试材，研究不同植物伴生番茄对番茄根结线虫病的防效以及对番茄生长的影响。初筛和复筛结果表明，普通白菜、分蘖洋葱、薄荷、茴香等4 种植物伴生能够显著降低番茄根结数量和根结指数，相对防效为58.7%～82.8%，且对番茄生长无显著抑制作用，可作为减轻番茄根结线虫病的有效伴生植物。
