- 摘要:
- 为进一步提高食用桔梗产量，改善根部质量，在播种前用基质进行土壤改良（加入不同比例的椰糠与草炭），采用不同密度进行组合处理，通过探究不同栽培密度与基质处理对食用桔梗各性状的影响，确定食用桔梗最佳栽培条件。结果表明：茎粗、分枝数、地上部鲜重、根径与单根鲜重受密度影响较大、差异显著，随着密度的降低呈上升趋势，而基质处理比较中3个处理并无显著差异；根长受基质处理影响更大、差异显著，在密度处理中3个处理无显著差异，B3（20%椰糠+20%草炭+60%原土）处理的根长显著高于其他两个处理；隶属函数分析结果表明食用桔梗最佳栽培组合为A2B3（栽培密度4 cm×4 cm，基质处理20%椰糠+20%草炭+60%原土）。
- Abstract:
- In order to further improve the yield and root quality of edible Platycodon grandiflorum,soil improvement was carried out with substrate before sowing (adding different proportions of coconut bran and peat),and combined treatment was carried out with different densities.The best cultivation conditions of edible Platycodon grandiflorumwere determined by exploring the effects of different cultivation densities and substrate treatments on various characters of edible Platycodon grandiflorum.The results showed that stem diameter,branch number,shoot fresh weight,root diameter and single root fresh weight were significantly affected by density,and increased with the decrease of density,but there was no significant difference among the three treatments; The root length of B3 (20% coconut bran + 20% peat + 60% native soil) was significantly higher than that of the other two treatments; The results of membership function analysis showed that the best cultivation combination of edible Platycodon grandiflorum was A2B3 (cultivation density 4 cm×4 cm),substrate treatment (20% coconut bran + 20% peat+60% original soil).
