人工摘花对大兴安岭地区桔梗产量和品质的影响

摘要

Objective] Effects of plucking flower on the yield and quality of P.grandilf orum were studied in order to provide theoretical basis for formulating the standard operating procedure of P.grandilf orum.[ Method] The randomized block design was used in the experiment. [ Result] The root length, root diameter, fresh weight of root, dry weight of root, total saponin and polysaccharide content could be increased significantly by plucking flower bud, and the dry weight of root could be increased by 41.2%.[Conclusion] The yield and quality of the un-derground part of P.grandiflorum can be improved significantly by plucking flower.%[目的]研究摘花对桔梗的产量和品质的影响，以期为桔梗规范化生产标准操作规程的制订提供理论依据。[方法]在大田条件下，采用随机区组设计进行试验。[结果]摘除花蕾可显著提高桔梗的根长、根粗、根鲜重、根干重、总皂苷和多糖含量，其中根干重可提高41．2％。[结论]在桔梗生长期摘除花蕾，能有效提高桔梗的地下部分产量和改善品质。
