Problems solved by technology

However, due to the low content of paeoniflorin cultivated by common cultivation methods, it cannot meet the requirement of the content of 1.8% stipulated in the Chinese Pharmacopoeia, thereby causing it to be unable to be used as a qualified medicinal material

Embodiment 1～12

[0168] We selected many places in Inner Mongolia, three northeastern provinces and Hebei to conduct artificial cultivation experiments of peony. The air, soil, and irrigation water of the selected plots met the aforementioned quality standards. Test the influence of different frozen soil depth, different soil, different rainfall, different organic matter content, and different soil types on the paeoniflorin content of red peony, see Table 1

[0169] Table 1 Paeoniflorin content of red peony in different regions and different cultivation conditions

[0170]

[0171] From the results in Table 1, it can be seen that the paeoniflorin content of the red peony roots in Examples 1-12 is above 3.2%.

Abstract

The invention discloses a cultivation method for improving paeoniflorin content of red paeony root. A plurality of cultivation measures are adopted for producing area environments of the red paeony root, seeds, selection and preparation of land, field management, pest control and prevention and harvesting; the areas where the rainfall is 200-800 mm and the maximum frozen soil depth is greater than 20 cm are selected, loose and fertile sandy loam or sand-mixed soil is selected for planting, and the organic matter content of the soil is greater than 1 percent. According to the cultivation method, the quality for cultivation of the red paeony root can be improved; cultivation experiments at twelve areas such as several areas of Inner Mongolia, Heilongjiang, Jilin, Liaoning and Hebei show that the paeoniflorin content is 3.2-4.5 percent, the supply of the artificially cultivated red paeony root serving as a medicinal raw material can be guaranteed, and finally the red paeony root can be used in place with gradually exhausted wild red paeony root.

Description

Technical field [0001] The invention relates to a cultivation method of Chinese medicinal materials, in particular to a cultivation method for increasing the content of effective components of red peony. Background technique [0002] Red peony root is Paeonia lactiflora Pall. (Paeonia lactiflora Pall.), a plant in the Ranunculaceae family. It is used as a medicine to clear away heat and cool blood, relieve blood stasis and relieve pain. It is used for warm toxins, spots, red eyes, swelling and pain, amenorrhea, dysmenorrhea, abdominal pain, bruises, carbuncle sores, bruises, and carbuncle sores. Paeoniflorin, the main component of red peony root, has anti-thrombosis, anti-platelet aggregation, lowering blood fat and anti-arteriosclerosis, beneficial to the cardiovascular system, anti-tumor and liver protection. [0003] For a long time, red peony has been mainly used wild red peony with high paeoniflorin content. However, as a major producer of China, due to long-term indiscrimina...
