Planting method for shortening planting cycle of white paeony root and improving yield and effective component content

Abstract

The invention provides a planting method for shortening a planting cycle of a white paeony root and improving yield and effective component content. On the basis of regular production planting, the planting method increases the steps that gibberellin is sprayed outside seedling roots at the beginnings of March and April of the first year and the second year at the growth stage, and chlormequat chloride is sprayed outside the roots at the late stage of blossom at the ends of June and July of the first year, the second year and the third year at the growth stage. The planting method is simple to implement, little in investment and large in gain, can shorten the time from seedling emergence to stem leaf ridge coverage of the white paeony root, and postpones the time of leaf yellowing and stem drooping of the white paeony root, thereby prolonging growth time of the white paeony root, strengthening effective component accumulation of the white paeony root, greatly improving the yield of the white paeony root, and improving effective component content of the white paeony root. The yield of the white paeony root is improved by above 10%, the connect an effective component paeoniflorin of the white paeony root is improved by above 8%, growth cycle of the white paeony root is shortened, original white paeony roots can be harvested after 4-5 years or longer time, and now the white paeony root can be harvested after 3-4 years.

Description

technical field [0001] The invention relates to a cultivation technique of Chinese herbal medicine, namely a cultivation method of Radix Paeoniae Alba.

Problems solved by technology

However, the traditional planting method of Radix Paeoniae Alba has a growth cycle of 4 to 5 years or longer, which is too long, and its annual growth period is particularly short. It only takes about 5 months from the emergence of seedlings in spring to the withering of leaves and stems. The time is shorter from the time when the stems and leaves are covered with ridges to the time when the stems and leaves are withered and yellow, so the growth period of the roots of Radix Paeoniae Alba is very short, which is not conducive to the growth of Radix Paeoniae Alba roots, and is not conducive to the accumulation of active ingredients in Radix Paeoniae Alba. The yield of Paeoniae Alba is limited, and the content of active ingredients in Paeoniae Alba is not very high. It will take 4 to 5 years or longer to harvest.
