Embodiment 1

[0022] 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. 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 460 μmol / L and 560 μmol / L, respectively, and the Tianqi plants were 3-year-old Tianqi plants.

Embodiment 2

[0024] 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. 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 560 μmol / L and 480 μmol / L, respectively, and the Tianqi plants were 3-year-old Tianqi plants.

Embodiment 3

[0026] 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 650 μmol / L and 370 μmol / L, respectively, and the Tianqi plants were 3-year-old Tianqi plants.

Abstract

The invention discloses a method for improving the content of ginsenoside Rd in cultivated pseudo-ginseng. 2-10 days before the pseudo-ginseng is harvested, a methyl jasmonate solution and a salicylic acid solution are sprayed to pseudo-ginseng plants alternately. By spraying the methyl jasmonate solution and the salicylic acid solution alternately to leaves of the pseudo-ginseng before the pseudo-ginseng is harvested, the high expression of the genes of key metabolism enzymes, such as squalene synthase, squalene epoxidase, glucosyltransferase, cytochrome P450 enzymes and the like, of ginsenoside Rd in the cultivated pseudo-ginseng is induced, and therefore the content of ginsenoside Rd is quickly increased in a short time.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine cultivation. More specifically, the present invention relates to a method for increasing the content of ginsenoside Rd 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 Tianqi. Ginsenoside Rd has a wide range of effects on the central nervous system, cardiovascular system, digestive system, immune system,...
