Abstract:
Taking Ligusticum chuanxiong Hort. as test materials,the effects of different concentrations of fulvic acid on agronomic traits,yield,quality and heavy metal content of Ligusticum chuanxiong Hort. were studied by random block design field experiment,in order to provide a reference for the rational application of fulvic acid on Ligusticum chuanxiong Hort..The results showed that leaf spraying of fulvic acid could significantly increase the tiller number and crown width of Ligusticum chuanxiong Hort..The yield of Chuanxiong Rhizoma was increased by 23.47% in H2 (1.0 kg?hm-2) and H3 (1.5 kg?hm-2) compared with CK.H3 (1.5 kg?hm-2) treatment could increase the contents of volatile oil and extract,while H1 (0.5 kg?hm-2) and H2 (1.0 kg?hm-2) treatment had little effect on water-soluble extract,alcohol-soluble extract,volatile oil and active components,but had great effect on the contents of plumbum(Pb),cadmium (Cd),arsenic (As),mercury (Hg) and cuprum (Cu) in Chuanxiong Rhizoma,among which the content of heavy metal cadmium (Cd) was positively correlated with the application concentration of fulvic acid.After treatment with different concentrations of fulvic acid，its content was 16.67% higher than that of CK.In conclusion,foliar spraying of fulvic acid could promote the yield and quality of Ligusticum chuanxiong Hort.,but increase the risk of excessive heavy metals.
