新型腐植酸类肥料对党参生长和品质的综合评价
Comprehensive evaluation of new humic acid fertilizer on growth and quality of Codonopsis pilosula
摘要
Abstract
In order to explore the effects of three humic acid fertilizers with different components on the growth and quality of Codonopsis pilosula,and screen out the best fertilizer,a field experiment was conducted with four treatments,including water(CK),humic acid fertilizer I(T1),humic acid fertilizer II(T2)and humic acid fertilizer III(T3),to explore the effects of different treatments on yield and quality of Codonopsis pilosula.Meanwhile,this study comprehensively evaluated the photosynthetic characteristics,carbon and nitrogen metabolism enzyme activities,growth and quality indicators of Codonopsis pilosula under different treatments.The results showed that all three humic acid fertilizers promoted the growth of Codonopsis pilosula,improved the photosynthetic efficiency and metabolic enzyme activity,thereby increasing the yield,and also promoted the accumulation of secondary metabolites.Compared with the CK treatment,the yields of T1,T2 and T3 treatments were significantly increased by 37.4%,41.1%and 54.9%,respectively;the contents of ethynyl glycosides and syringin in T3 treatment were significantly increased by 10.4%and 6.7%,respectively;the contents of atractylenolide III in T2 and T3 treatments were significantly increased by 11.6%and 20.2%,respectively.The results of principal component analysis showed that T3 treatment had the best effect on the growth and quality of Codonopsis pilosula.Thus,humic acid fertilizers could promote the growth and secondary metabolite accumulation of Codonopsis pilosula by improving root activity,photosynthetic efficiency and carbon and nitrogen metabolic enzyme activity,and the promotion effect of humic acid fertilizer III was the best.The research results provided a new approach for high-yield and high-quality cultivation of Codonopsis pilosula.关键词
