Abstract:
With Coptis chinensis in high-yielding soil as the object,the growth regularity of plant and dynamic change of alkaloid content was studied. The plant growth model of C. chinensis was constructed. The plant height equation was =3.030 9+0.732 6-0.009 6²,the number of leaves equation was =111.882 6-2 234.881 7/+15 218.960 8/²-31 740.960 8/³,the leaf area equation was =-217.136 1+30.552 2-0.359 0²,the roots talk biomass equation was =-2.748 8+0.210 3+0.006 4²,the number of rootstalk equation was =-1.246 0+0.192 6+0.000 8²,the fibrous root biomass equation was =-4.973 5+0.589 4 -0.002 6². The results indicated that the number of leaves and leaf area were increasing continuously after seedling transplanting,the leaf area of 3-year-old C. chinensis reached a maximum value of 425.83 cm²/plant,after declining.The number of leave of 5-year-old C. chinensis reached a maximum value of 70.91. With the increasing of years of growth, the number of rootstalk and rootstalk biomass of C. chinensis was increasing continuously. The biomass growth of 3-year-old and 4-year-old rootstalk was the fastest in the whole development stage of C. chinensis,the annual increase of more than 300%. The change curve of rootstalk number, rootstalk biomass and fibrous root biomass in the whole growth stage was a s-type.The dry matter partition of leafwas the highest in 1-year-old C. chinensis, and then gradually decreased,the change trend of dry matter partition of rootstalk was just the opposite, the dry matter partition of fibrous root increases with the increase of the growing year, reaching the maximum value in 3-year-old, then gradually lower trend. The root-shootratio of 1-year-old C. chinensis was the smallest, then gradually increases, the growth center gradually shifted to the roots from stems and leaves, The weight of underground part of 3-year-old C. chinensis exceeded the aboveground part, the 5-year-old C. chinensis root-shoot ratio reached the maximum value of 1.91:1.With the increasing of years of growth, the contents of coptisine, berberine, epiberberine and palmatine in rootstalk was increasing continuously. The jatrorrhizine content in 2-year-old C. chinensis was significantly lower than that in other years, the content was no significant change after that. The columbamine content reached a maximum value in 3-year-old C. chinensis,then the decreased gradually. The content of magnoflorine gradually increased and reached maximum value in 5-year-old C. chinensis.
