Embodiment 1

[0033] The residue or Artemisia annua stalk after preparation of artemisinin is extracted by the above-mentioned method, and the concentrated solution is diluted to different concentrations. Uniform corn seeds were selected, soaked in different concentrations of artemisinin extracts after disinfection and cleaning, germination was accelerated, and seeds were sown. The water test was used as a control. Seed soaking treatment with appropriate concentration of artemisinin extract plays an important role in improving seed growth rate and vigor, among which 10 -2 ~10 -4 Compared with the control, ml / L reached a significant level. This treatment also promotes the sturdiness and dry matter accumulation of corn seedlings, the root system is developed, the root activity is improved, the amylase activity is enhanced, and the photosynthetic rate is increased, which is of great help to the rapid transformation of plants from heterotrophic to autotrophic and the accumulation of organic ma...

Embodiment 2

[0037] The artemisinin extract and filtrate concentrate was diluted to different concentrations. Uniform corn seeds were selected and soaked in different concentrations of artemisinin extracts for 1 day after disinfection and cleaning. Water immersion test was used as a control. The day and night temperature is 30 / 20°C to cultivate seedlings for later use. In the experiment, a PEG (polyethylene glycol) concentration (W / V) of 15% (-0.4 MPa) was used to form drought stress, and the seedlings were transferred to the drought stress and continued to be cultivated. Soaking seeds with appropriate concentration of artemisinin extract plays an important role in improving growth rate and vitality. of which 10 -3 Compared with the control, several indicators in ml / L reached a significant level. If the concentration of 0.5μg.L is added on this basis -1 KT-30, a cytokinin substance, has a better effect than simply extracting the filtrate concentrate with artemisinin. The treatment als...

Embodiment 3

[0041] Artemisinin extraction and filtrate concentrated solution was diluted to different concentrations, and sprayed on corn seedlings, while the control was only sprayed with the same amount of water. In the experiment, a PEG (polyethylene glycol) concentration (W / V) of 15% (-0.4 MPa) was used to form drought stress, and corn seedlings with two to three leaves were transferred to drought stress conditions for further cultivation. After treatment with an appropriate concentration of artemisinin extract, the growth of corn seedlings can be regulated. Not only the plants grow robustly, but also the leaves are thicker, the chlorophyll content is higher, the photosynthetic rate is increased, and the soluble sugar and protein content of the plants are also significantly increased. Among them, 10 -2 The ml / L concentration solution is the most effective. Compared with the control, the activities of superoxide dismutase (SOD) and peroxidase (POD) are significantly increased, the cont...

Abstract

The invention relates to a control agent and an anti-adversity agent of plant growth, which adopts southernwood, a Chinese traditional medicine, namely Artemisia annua L, as raw material, or adopts the secondary substances (also containing small amount of the artemisinin which is not completely extracted) which are abundant in the large amount of residues and concentrated mother solution after artemisinin is extracted by organic solvent. On the one hand, the invention does not influence the extraction of the artemisinin used for pharmaceuticals, on the other hand, the invention enhances the added value of the products of the southernwood, turns wastes into benefits and is good for environment protection and green production. The product of the invention is characterized by wide physiological effect, being safe and innoxious, being no pollution, being environment-friendly, easy obtaining of raw materials and low cost.

Description

technical field [0001] The invention relates to the technical field of plant growth regulation and stress resistance, in particular to the new application of Artemisia annua extract in agriculture, specifically the application of Artemisia annua extract in plant growth regulation and stress resistance. Background technique [0002] Chinese scientists isolated artemisinin for the first time in the 1970s from the traditional Chinese medicine Artemisia annua (Artemisia annua L.). A large number of physical and chemical experiments, pharmacological studies and clinical applications at home and abroad have shown that artemisinin is an effective antimalarial component. It is believed that the discovery of artemisinin is a major breakthrough in the history of antimalarial research and has become an antimalarial drug recommended by the World Health Organization (Chen Yang et al. , 1998). my country has built a large-scale production base of Artemisia annua, and the series of produc...
