【摘要】 【目的】通过对平卧菊三七根部病害开展绿色防治试验，以探讨对其根部病害绿色防治的最佳效果。【方法】通过施用中药渣和竹炭有机肥做基肥和追肥改良土壤，采用壳聚糖和枯草芽孢杆菌制剂溶液灌根方法防治根部病害，以枯萎株率与严重度为评价指标，统计分析各处理组与对照组的试验结果，比较各种处理对其根部病害的防控效果。【结果】施用中药渣和竹炭有机肥试验地平卧菊三七的枯萎株率分别控制在3.54%和5.09%，与对照组相比，枯萎植株减少了22.78%和21.23%(P<0.01)；用壳聚糖和枯草芽孢杆菌处理植株根部，植株枯萎率分别控制为11.86%和14.27%，与对照组试验相比，植株枯萎率分别降低了19.96%和17.55%(P<0.05)，对根部病害的防治效果分别为75.01%和68.71%。【结论】施用中药渣和竹炭有机肥，以及壳聚糖和枯草芽孢杆菌制剂控制平卧菊三七根部病害，根部病害明显减少，防治效果均显著，绿色防控技术组合简便实用，为平卧菊三七根部病害的绿色防控及生态种植提供参考。更多还原

【Abstract】 [Objective] This article presents a green control experiment of root diseases in Gynura procumbens(Lour) Merr. so as to obtain the best control effect and high-quality. [Method] By applying traditional Chinese medicine residues and bamboo charcoal organic fertilizer as the base fertilizer and topdressing to improve the soil,the root diseases were prevented and controlled by using chitosan and Bacillus subtilis preparation solution for root irrigation. The rate and severity of withered plants were used as evaluation indicators, and the experimental results of each treatment group and control group were statistically analyzed to compare the prevention and control effects of various treatments on root diseases. [Result] The application of traditional Chinese medicine residues and bamboo charcoal organic fertilizer resulted in a control rate of 3.54% and 5.09% for the withered plants of Gynura procumbens, respectively. Compared with the control group, the number of withered plants decreased by 22.78%and 21.23%(P<0.01); the treatment of plant roots with chitosan and Bacillus subtilis resulted in a control rate of 11.86% and 14.27% for wilting plants, respectively. Compared with the control group experiment, the wilting plant rates decreased by 19.96% and 17.55%, respectively(P<0.05), and the control effects on root diseases were 75.01%and 68.71%, respectively. [Conclusion] The application of traditional Chinese medicine residues and bamboo charcoal organic fertilizer, as well as chitosan and Bacillus subtilis preparations, has a significant effect on controlling root diseases of Gynura procumbens. The root diseases are significantly reduced, and this combination of prevention and control techniques is simple and practical. The green prevention and control technologies provide references for the ecological cultivation of Gynura procumbens.更多还原
