Abstract:
OBJECTIVETo select the optimum formula fertilization of Isatis indigotica through analyzing the yield and contents of polysaccharide of Radix Isatis for different treatments.
METHODAn orthogonal experiment design on the basis of three factors and four levels was applied for studying the effect of formula fertilization on yield. The contents of polysaccharides were determined with phenol-witriolic colorimetry.
RESULTThe optimum formula fertilization of Radix Isatis was carbamide 869.0 kg x hm(-2), superphosphate 1 428.6 kg x hm(-2) and potassium sulfate 0 kg x hm(-2).
CONCLUSIONSuperphosphate can observably influence the yields of Radix Inditis. while carbamide influence the contents of polysaccharide of Radix Inditis.
