摘要:

研究旨在考查中药复方抑菌剂对太子参连作地田间病害的防效及产质量的影响。选用连作2年太子参种植地块,通过完全区组小区试验考察不同处理效果。抑菌剂1号处理太子参病害发生率比对照降低82.2%(P<0.01),病指降低14.7倍,防效为93.0%(P<0.01),产量提高43%(P<0.05),总多糖提高51%。1号抑菌剂与1号抗病毒剂联用对病毒病防效可达99.4%(P<0.01),该组合与化学药剂联用后对病毒病防效可达99.5%(P<0.01);2个处理产量均比对照提高1倍;1号抑菌剂与1号抗病毒剂联用,总多糖含量提高15%,环肽B含量提高12%;单用1号抑菌剂,环肽B提高也为12%。中药复方抑菌剂1号对病毒病防治和产质量提高具有显著效果。

Abstract:

The aim of this study is to investigate the effect of Chinese herbal compound bacteriostatic agent on field disease control and yield and quality of radix pseudostellariae in continuous cropping field. Two-year continuous cropping plots of radix pseudostellariae were used, and the effect of different treatments was investigated through complete block plot experiment. The disease incidence of radix pseudostellariae treated with bacteriostatic agent No. 1 decreased by 82.2% (P<0.01), the disease index decreased by 14.7 times, the control effect was 93.0% (P<0.01), the yield increased by 43% (P<0.05), and the total polysaccharide increased by 51%. The combined effect of No. 1 bacteriostatic agent and No. 1 antiviral agent was 99.4% (P<0.01), the combined effect of this combination with chemical agents was up to 99.5% (P<0.01). The yield of the two treatments was twice as high as that of the control. When bacteriostatic agent No. 1 was combined with antiviral agent No. 1, the content of total polysaccharide and cyclic peptide B increased by 15% and 12% respectively, and the content of cyclic peptide B also increased by 12% with the application of bacteriostatic agent No. 1 alone. In conclusion, Chinese herbal compound bacteriostatic agent No. 1 has significant effect on the prevention and treatment of virus disease and the improvement of yield and quality of radix pseudostellariae.

Key words: radix pseudostellariae, Chinese herbal compound preparation, bacteriostasis, continuous cropping, disease control effect, yield and quality
