摘要
[目的]探讨适宜的烤烟间作防控烟草黑胫病。[方法]通过田间试验研究黄豆、红薯、韭菜、旱稻、大麦、芹菜等几种间作物对烟草黑胫病的防控效果。[结果]除黄豆外，间作红薯、旱稻、韭菜、大麦、芹菜对黑胫病有一定的防效，防效从大到小依次为间作大麦、芹菜、韭菜、红薯、旱稻。同一种间作物不同的生育阶段对黑胫病菌的抑制效果不同，但都是在其地上部分充分发育到最大程度时对黑胫病的控制效果最好。[结论]试验结果为烟叶生产上防控烟草黑胫病提供了理论依据。
Abstract
Objective] The aim was to choose suitable crops intercropping with the flue-cured tobacco for controlling the tobacco black shank disease.[ Method] Field experiments were carried out to study effects of the soybean, the sweet potato, the fragrant-flowered garlic, the up-land rice, the barley and the celery on tobacco black shank disease.[Result] Besides the soybean, the sweet potato, the upland rice, the fra-grant-flowered garlic, the barley and the celery has certain control effect on tobacco black shank disease .The effects of intercropping crops on controlling tobacco black shank disease were in the order of barley >celery >fragrant-flowered garlic >sweet potato >upland rice.The i-dentical inter-species crops different birth stage was different to Phytophthora parasitica var.nicotianae suppression effect, and it was grown fully when its aerial parts to the greatest degree the control effect was best to the black shank disease .[ Conclusion] The results provided theo-retical basis for the control of tobacco black shank disease in production.
