Abstract:
Taking Saposhnikovia divaricata as test material,water extraction and alcohol precipitation method was used to extract polysaccharides in Saposhnikovia divaricata (S.divaricata) and the content of polysaccharides was determined by phenol sulfuric acid ultraviolet spectrophotometry.According to standard of China,the pH,rapidly available nitrogen(N),phosphorus(P)and kalium(K),total nitrogen and organic matter contents in rhizosphere soils of S.divaricata were measured.The effects of rhizosphere soil chemical properties on the contents of polysaccharides in S.divaricata collected from different regions in different harvest times were analyzed with SPSS 13.0 software.The results showed that the contents of polysaccharides in the roots of S.divaricata were significantly different with different collection regions and times.Only the polysaccharides contents of S.divaricata collected in October showed a significantly non-linear correlation with the rapidly available K content in the rhizosphere soils(P＜0.05).The pH and hydrolysable nitrogen content with the content of available phosphorus,the hydrolysable nitrogen and available phosphorus contents with the available kalium content,and the hydrolysable nitrogen and available phosphorus contents with the organic matter content were significantly correlated(P<0.01).The correlation of available kalium with the organic matter changed with the change of the collecting time,in which the differences in August(P<0.01)and October(P<0.05)were significant.Significant correlations of the hydrolysable nitrogen and organic matter contents with the total nitrogen content were found(P<0.05).The polysaccharides contents of S.divaricata collected at different harvest times could be affected by the different rhizosphere soils,especially those collected in October were significantly influenced by the available potassium content of soils.The content optimization and stability of nutrients in the soil could improve the productivity of polysaccharides in the S.divaricata.
