Preliminary Study on Substrate Screening for Soilless Seedling Cultivation of Panax notoginseng
Objective To study the soilless seedling breeding medium of Panax notoginseng,find out the best substrate formula,change the traditional seedling cultivation method,expand the seedling cultivation channel,and improve the quality grade of Panax notoginseng seedling.Methods Using red loam,peat,volcanic ash,perlite,zeolite,vermiculite,river sand and organic fertilizer as raw materials,the matrix was prepared according to different combinations and dosage.Statistical and analysis of experimental data to select the best formula for the soilless seedling of Panax notoginseng.Results Treatment C(river sand∶peat∶perlite=3∶4∶3)was the best formula for the soilless cultivation of Panax notoginseng,followed by treatment E(vermiculite∶zeolite∶organic fertilizer=2∶5∶3)and treatment Ⅰ(river sand∶peat∶perlite=3∶3∶4).Conclusion Soilless seedling cultivation can improve the emergence rate and retention rate of Panax notoginseng,optimize the agronomic traits,reduce the rate of disease and insect pests,increase the fresh weight per plant,and improve the quality grade of Panax notoginseng.
