摘要
为探究不同播期对河南产桔梗根品质的影响,将春、秋、冬栽培的桔梗根进行比较,分析根部农艺性状以及药用成分桔梗皂苷D含量在各播期间的差异性。结果表明:播期对桔梗主根长、根粗、根鲜质量、干质量、桔梗皂苷D含量的影响均达到极显著水平(P<0.01)。综合考虑各性状指标和成分含量,以秋播最好、冬播其次、春播最差,确定河南地区桔梗的最佳播期为9月底的秋播。
In order to explore the effects of different sowing dates on the root quality of Platycodon grandiflorum in Henan,P. grandiflorum was sowed in spring,autumn and winter,and then the differences in the root agronomic traits and the content of medicinal component platycodin D were analyzed among different sowing periods. The results showed that the effect of sowing date reached extremely significant level( P < 0. 01) on root length,root diameter,root fresh weight,dry weight and platycodin D content. Considering agronomic traits and medicinal components,the best comprehensive quality was obtained by sowing in autumn,next was in winter and the worst was in spring. So it can be determined that the suitable sowing period of P. grandiflorum in Henan area is the end of September.
