Embodiment 1

[0021] Before transplanting Tianqi seed strips, treat the seed strips with UV-B radiation, and the UV-B radiation dose is 5kj.m -2 .d -1 , the treatment time is 3 days, and the Tianqi seed strips are transplanted to the planting ground after the treatment. 2 days before Tianqi harvest, the leaf surface of Tianqi plant was alternately sprayed with methyl jasmonate solution and salicylic acid solution in the morning, middle and evening, and the methyl jasmonate solution and salicylic acid solution were sprayed each time. The acid solution was kept until the leaves dripped, the concentrations of the methyl jasmonate solution and the salicylic acid solution were 500 μmol / L and 400 μmol / L respectively, and the Tianqi plants were 3-year-old Tianqi plants.

Embodiment 2

[0023] Before transplanting Tianqi seed strips, treat the seed strips with UV-B radiation, and the UV-B radiation dose is 3kj.m -2 .d -1 , the treatment time is 5 days, and the Tianqi seed strips are transplanted to the planting ground after the treatment. Eight days before Tianqi was harvested, the leaf surface of the Tianqi plant was alternately sprayed with methyl jasmonate solution and salicylic acid solution once in the morning, middle and evening, and methyl jasmonate solution and salicylic acid solution were sprayed each time. The acid solution was kept until the leaves dripped, the concentrations of the methyl jasmonate solution and the salicylic acid solution were 420 μmol / L and 310 μmol / L, respectively, and the Tianqi plants were 3-year-old Tianqi plants.

Embodiment 3

[0025] Before transplanting Tianqi seed strips, treat the seed strips with UV-B radiation, and the UV-B radiation dose is 4kj.m -2 .d -1 , the treatment time is 4 days, and the Tianqi seed strips are transplanted to the planting ground after the treatment. 10 days before the harvest of Tianqi, the leaf surface of the Tianqi plant was alternately sprayed with methyl jasmonate solution and salicylic acid solution once in the morning, middle and evening, and methyl jasmonate solution and salicylic acid solution were sprayed each time. The acid solution was kept until the leaves dripped, the concentrations of the methyl jasmonate solution and the salicylic acid solution were 250 μmol / L and 200 μmol / L respectively, and the Tianqi plants were 3-year-old Tianqi plants.

Abstract

The invention discloses a method for increasing the content of ginsenoside Re in panax notoginsen cultivation. The method includes that 2-10 days before harvesting of panax notoginseng, panax notoginseng plants are alternatively sprayed with a methyl jasmonate solution and a salicylic acid solution. Leaves of the panax notoginseng are alternatively sprayed with the methyl jasmonate solution and the salicylic acid solution before harvesting of the panax notoginseng, high expression of key enzyme genes of ginsenoside Re metabolism in panax notoginseng cultivation is induced, and the content of the ginsenoside Re can be rapidly increased in the short term.

Description

technical field [0001] The invention relates to the field of medicinal material cultivation. More specifically, the present invention relates to a method for increasing the content of ginsenoside Re in cultivated Tianqi. Background technique [0002] Tianqi [Panax notoginseng (Burk.) F.H.Chen] is a perennial herbaceous plant of the Araliaceae ginseng genus. It is a famous traditional Chinese medicine in my country. It is mainly used as a medicine with roots and rhizomes. It is warm in nature, sweet in taste, and slightly bitter. , the effect of reducing swelling and relieving pain. Tianqi is the main raw material of famous Chinese patent medicines such as Yunnan Baiyao, Compound Danshen Tablets (Drip Pills), Zhangzhou Pien Tze Huang, Xueshuan (Sai) Tong, and Dongbeihongyao. Ginsenoside Re is one of the main active ingredients of Tianqizhong. Ginsenoside Re has good pharmacological activity and is mainly used in many diseases such as nerves, immunity, cardiovascular and cere...
