摘要: 为了探讨不同周年轮作模式对烟草根结线虫的影响。在云南省曲靖市沾益区进行田间定位试验,以烤烟-冬闲-烤烟为对照,设烤烟-绿肥-高粱、烤烟-绿肥-万寿菊、烤烟-燕麦-万寿菊、烤烟-大麦-万寿菊、烤烟-藜麦-万寿菊5个轮作处理,研究不同轮作处理在不同时期对烟草根结线虫数量及烤烟发病率、病情指数的影响。结果表明,在大麦、燕麦、藜麦收获后土壤根结线虫数量显著低于烤烟-冬闲-烤烟处理(CK)烤烟移栽前,表明小春种植大麦、燕麦、藜麦相对于冬闲可以在一定程度上抑制根结线虫数量增长。烤烟-燕麦-万寿菊、烤烟-大麦-万寿菊、烤烟-藜麦-万寿菊处理在万寿菊收获后,土壤根结线虫数量较万寿菊盛花期分别下降了14.9%、20.0%和41.3%,表明烤烟与燕麦、大麦、藜麦、万寿菊进行周年轮作可以在一定程度上降低土壤根结线虫的数量。

Abstract: In order to explore the effects of different annual crop rotation patterns on tobacco root-knot nematodes, a field positioning experiment was carried out in Zhanyi District, Qujing City, Yunnan Province. With flue-cured tobacco-winter fallow-flue-cured tobacco as the control, five rotation treatments of flue-cured tobacco-green manure-sorghum, flue-cured tobacco-green manure-marigold, flue-cured tobacco-oats-marigold, flue-cured tobacco-barley-marigold, flue-cured tobacco-quinoa-marigold were set up to study the effects of different rotation treatments on the number of tobacco root-knot nematodes, the incidence rate and disease index of flue-cured tobacco at different stages. The results showed that the number of root-knot nematodes in the soil after harvesting barley, oats, and quinoa was significantly lower than that before transplanting in the tobacco winter fallow (CK) treatment, indicating that planting barley, oats, and quinoa in winter could inhibit the growth of root-knot nematodes compared to winter fallow. After harvesting marigold, compared to the peak flowering period of marigold flowers, the number of soil root-knot nematodes decreased by 14.9%, 20.0%, and 41.3% in the treatments of tobacco-oat-marigold, tobacco-barley-marigold, and tobacco-quinoa-marigold, respectively. It indicated that annual rotation of tobacco with oats, barley, quinoa, and marigold could reduce the number of soil root-knot nematodes to some extent.

Key words: flue-cured tobacco, annual crop rotation patterns, root-knot nematodes
