- 摘要:
- 以党参为试材,通过打顶、摘蕾、喷施生长调节剂的方法控制党参结实,研究了不同控制结实方法对党参产量、质量和经济效益的影响。结果表明:不同控制结实方法均显著增加了党参药材产量,减少了种子的产量,但党参田整体经济效益并未显著升高。打顶和摘蕾措施对党参药材质量的影响主要体现为对性状质量的提升;施用激素对党参质量的影响主要体现在支根数量增多和有效组分含量降低2个方面。在党参生产中无需控制结实,采用药材和种子并行的生产方式可降低生产成本,增加经济收益。
- Abstract:
- Taking Codonopsis pilosula as test material,the seed quality was analyzed based on the International Seed Test Agreement,ethanol extract was determined using ChP(2015 Edition) by means of the topping,cut-flower,spraying plant growth regulators changing reproductive growth of Codonopsis pilosula.Spectrophotometry was selected to determine the content of polysaccharide,concentration of lobetyolin was measured by HPLC.The results showed that three kinds of different changing reproductive growth treatments increased root yield and decreased seed yield obviously,but field economic benefit had not increase significantly.The best root property had retained by the topping and cut-flower treatment,plant growth regulators affected total lateral root number and reduced index constituents as well.Keeping the production of Codonopsis pilosula medicines and seeds without any control of reproductive growth in the production for C.pilosula in arid hilly area,production costs might be decreased and promoted a better production economy.
