Method for planting radix paeoniae alba with high yield and high content of effective components

Abstract

The invention discloses a method for planting radix paeoniae alba with high yield and high content of effective components. The step of spraying gibberellin outside the roots of the radix paeoniae alba in the growth period between the early March and the early April of the first year and the second year is additionally adopted on the basis of the original conventional producing and planting steps. The gibberellin spraying solution is prepared according to the following steps: taking 0.25-0.75g of gibberellin, adding 10ml of ethanol to dissolve the gibberellin fully, adding the ethanol solution of the gibberellin into 50l of clean water, and stirring to mix uniformly to obtain the gibberellin spraying solution. The method is easy to implement and has the advantages of low investment and high yield. Due to the adoption of the method, the time lasting from the emergence of seedlings to the coverage of the ridges by the stems and leaves of the radix paeoniae alba can be shortened, the leave yellowing time and the stem withering time of the radix paeoniae alba can be delayed so that the growth period of the roots of the radix paeoniae alba can be prolonged, the accumulation of the effective components in the roots of the radix paeoniae alba can be improved, and the yield and the content of the effective components of the radix paeoniae alba can be increased greatly, wherein the yield can be increased by more than 38%, and the content of the effective component which is the paeoniflorin can be increased by more than 16%.
