Objective:
To study the effects of fertilizer on polysaccharide content, flavonoids content and output of Radix Hedysari in different growth stage.
Methods:
The content of polysaccharide and flavonoids in different part of Radix Hedysari was examined in different growth stage by using spectrophotometric method.
Results:
Fertilizer could improve polysaccharide content of Radix Hedysari aerial part and total flavonoids content of root, increase polysaccharide accumulation amount of Radix Hedysari root in middle and late growth stage. The output of Radix Hedysari in the fertilizer group was 1430 kg/hm2 higher than that of no treatment group.
Conclusion:
Fertilizer can improve output and quality at harvest time in Radix Hedysari cultivation.
