Embodiment 1

[0008] The definition of embodiment 1 Scutellaria baicalensis growth and development stage

[0009] According to bibliographical reports (Li Hua, Huang Luqi, Yang Bin, Feng Xuefeng, Li Wei, Tang Na, the change law of the effective components of Scutellaria baicalensis in different growth and development stages, Chinese Herbal Medicine, 2008, 4: 604-607) determine the growth and development of Scutellaria baicalensis involved in the present invention. The stages are:

[0010] 1. The seedling stage is 8-10 pairs of leaves;

[0011] 2. The leaf-expanding period is the period when there are more than 10 pairs of leaves and no flowering;

[0012] 3. The early stage of flower and fruit is the period of flowering and no fruit;

[0013] 4. The mid-flowering and fruiting period is the period of flowering and fruiting;

[0014] 5. The end of the flower and fruit period is the period when the flowering period is over and the fruit is produced;

[0015] 6. The withering period is the ...

Abstract

By spraying mepiquat chloride plant growth regulator onto leaves, the content of flavone active components in roots of medicinal plants can be increased. The mepiquat chloride treatment is performed in a leaf expansion period. The method is suitable for root medicinal materials containing flavones compounds, such as scutellaria baicalensis.

Description

technical field [0001] The invention relates to the cultivation of Chinese medicinal materials and belongs to the field of traditional Chinese medicine agriculture. Background technique [0002] The content of active ingredients is an important index to measure the quality of Chinese medicinal materials, which is affected by many factors during the cultivation process, including developmental stage, environment and cultivation conditions. These factors must be optimized to achieve an increase in the content of active ingredients in cultivated medicinal materials. [0003] Plant growth regulators can affect the growth and development of plants and affect the natural rhythm of plants. More specifically, plant growth regulators can reduce plant height, promote seed germination, induce flowering, reduce pests and diseases, etc., but there is no report on the use of plant growth regulators to control the content of active ingredients in traditional Chinese medicinal materials in...
