Embodiment 1

[0014] Embodiment 1: spraying sodium selenite to promote the accumulation of notoginseng in Panax notoginseng, comprising the following steps:

[0015] (1) Spray the sodium selenite solution on the leaves of Panax notoginseng grown for 3 years;

[0016] (2) The spraying concentration of sodium selenite solution is 0, 1, 5, 10 mg / L;

[0017] (3) Sodium selenite was sprayed after Panax notoginseng began to bloom, and then once every two weeks, for a total of 4 times.

Embodiment 2

[0018] Embodiment 2: adopt the Radix Notoginseng after the treatment of Example 1 to measure the content of Panax notoginseng

[0019] Gather Panax notoginseng after 120 days of spraying for the first time, measure the content of notoginseng in the above-ground part and the underground part; find that the content of notoginseng in the aerial part of Panax notoginseng is the highest under the treatment of 5mg / L sodium selenite solution, is it true? The application of sodium selenite is 2.10 times; under the treatment of 1mg / L and 10mg / L sodium selenite, the content of notoginseng in the shoot is 1.5 times and 1.4 times of that of no application; Under sodium treatment, the content of notoginseng in the underground part was 1.2-1.7 times that of no treatment ( figure 1 ).

Embodiment 3

[0020] Embodiment 3: Determination of antioxidant enzyme activity and non-enzyme substance content by using Radix Notoginseng processed in Example 1

[0021] The notoginseng was harvested 120 days after the first spraying. With the increase of the concentration of sodium selenite solution foliar spraying, the antioxidant enzyme activity of the aboveground and underground parts of notoginseng was significantly enhanced under the treatment of 5 mg / L concentration , the maximum increases of SOD, POD and CAT activities were 125.18%, 48.48% and 71.15% in the aboveground part, and 143.94%, 52.29% and 71.24% in the underground part ( figure 2 , 3 , 4). The contents of GSH and ASA in the shoots and underground parts of Panax notoginseng were the highest under the treatment of 5 mg / kg sodium selenite ( Figure 5 , 6 ).

Abstract

The invention discloses a method for improving the content of dencichine in pseudo-ginseng. A sodium selenite solution is sprayed after the flowering of the pseudo-ginseng, then the sodium selenite solution is sprayed to leaves once every two weeks, the continuous spraying is performed for 3 to 4 times. Experiments prove that the content of the dencichine in leaves and roots after spraying the sodium selenite solution to the leaves of the pseudo-ginseng is 1.4 to 2.1 times and 1.2 to 1.7 times of that without spraying the sodium selenite solution, and the activity of an antioxidant enzyme system is enhanced in the pseudo-ginseng. The method of the invention is simple, efficient and convenient to implement and is suitable for being popularized and applied in industrial production and agricultural production.

Description

technical field [0001] The invention discloses a method for increasing the content of notoginseng, an effective medicinal component in medicinal plant Panax notoginseng, and belongs to the field of cultivation of traditional Chinese medicinal materials. Background technique [0002] Panax notoginseng (Bruk) F. H. Chen is a perennial herbaceous plant of the Araliaceae ginseng genus. Its dried roots are used as medicine. It has two-way regulating functions of hemostasis and blood circulation. Saponins in notoginseng are the main blood-activating substances, and notoginseng is the main hemostatic substance. Panax notoginseng is a special non-protein amino acid, pharmacologically it mainly exhibits effects such as hemostasis, anti-lipolysis, and promotion of fat synthesis. It is the main component of hemostatic drugs such as Yunnan Baiyao. Therefore, increasing the content of notoginseng in the notoginseng medicinal material is of great significance for improving the efficacy ...
