CN-116491381-B - Method for improving quality of radix scutellariae medicinal material cultivated based on moisture ecological regulation measures

Abstract

The invention discloses a method for improving the quality of a cultivated baical skullcap root medicinal material based on a moisture ecological regulation measure, belongs to the field of ecological planting of Chinese medicinal materials, and solves the problems of degradation and unstable quality of baical skullcap root germplasm in the prior art. The method comprises the following steps of naturally growing according to conventional daily management after the radix scutellariae is sown, measuring the saturated water content of the soil for cultivating the radix scutellariae, classifying the water environment of the radix scutellariae according to the water content of the soil, dividing the water environment into normal water, slight drought, moderate drought and severe drought, monitoring the water content of the soil for cultivating the radix scutellariae in the next 9-10 months, applying the saturated water content once when the water content of the soil reaches the moderate drought level, monitoring the change of the water content of the soil for cultivating the radix scutellariae every day, and digging the radix scutellariae when the water content of the soil for cultivating the radix scutellariae is at the light and moderate drought level. The invention creatively improves the content of the effective components in the baical skullcap root medicinal material by a mode of manual water regulation.

2. 2. The method for improving the quality of medicinal materials for cultivating radix scutellariae based on the measure of moisture ecological regulation according to claim 1, wherein radix scutellariae is sown in 4 months a year.
3. 3. The method for improving the quality of the medicinal materials for cultivating radix scutellariae based on the water ecological regulation measures according to claim 1, wherein in the step 3, the water content of the soil for cultivating radix scutellariae is monitored at regular time every day after the saturated water content is applied once.
4. 4. The method for improving the quality of medicinal materials for cultivating radix scutellariae based on the measure of water ecological regulation and control according to claim 1, wherein radix scutellariae is picked up when the water content of the soil of the radix scutellariae is mild drought.

Description

Method for improving quality of radix scutellariae medicinal material cultivated based on moisture ecological regulation measures Technical Field The invention belongs to the field of ecological planting of traditional Chinese medicinal materials, and particularly relates to a method for improving the quality of a medicinal material for cultivating radix scutellariae based on a moisture ecological regulation measure. Background Radix Scutellariae is one of the most commonly used Chinese medicinal materials, and the original plant is perennial herb Scutellaria baicalensisGeorgi of Scutellaria of Labiatae. Currently, wild radix scutellariae resources are gradually exhausted, and cultivated radix scutellariae becomes a main source of radix scutellariae medicinal materials. However, the cultivation of scutellaria baicalensis has the problems of germplasm degradation, unstable quality and the like. The unstable quality will affect the drug effect, and further restrict the development of the Baical skullcap industry. Baical skullcap root is mainly distributed in northeast, north China, northwest, east China and other provinces, and is mainly used in meadow grasslands, sandy grasslands, hilly lands and dry hilly lands. The quality of the baikal skullcap root medicinal materials is greatly different due to the great difference of ecological environments of all places. According to the research reports, the content of baicalin in standard components of the quality of the radix scutellariae medicinal materials produced by different production methods is greatly different, and the stability of the quality of the radix scutellariae medicinal materials and the quality of the radix scutellariae medicinal materials produced by different production methods are obviously influenced. Therefore, the method for planting the scutellaria baicalensis improves the quality of medicinal materials of the scutellaria baicalensis by regulating and controlling the cultivation environment of the scutellaria baicalensis, and the method becomes a problem to be solved by those skilled in the art. Disclosure of Invention The invention aims to provide a method for improving the quality of a medicinal material for cultivating baical skullcap root based on a moisture ecological regulation measure, which solves the problems of degradation and unstable quality of the germplasm of the baical skullcap root in the prior art. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: the invention provides a method for improving the quality of medicinal materials for cultivating radix scutellariae based on a moisture ecological regulation measure, which comprises the following steps: Step 1, after the baikal skullcap root is sown, natural growth is managed according to routine daily; Step 2, measuring the saturated water content of the soil for cultivating the scutellaria baicalensis, classifying the water content environment of the scutellaria baicalensis according to the water content of the soil, and dividing the water content into normal water, slight drought, moderate drought and severe drought; Step 3, monitoring the moisture of the soil for cultivating the baical skullcap root in 9-10 months of the next year, applying saturated moisture content once when the moisture content of the soil reaches a moderate drought level, monitoring the change of the moisture content of the soil for cultivating the baical skullcap root every day, and digging the baical skullcap root when the moisture content of the soil for cultivating the baical skullcap root is not lower than the moderate drought level; wherein step1 and step 2 have no time sequence. In the growth period of radix Scutellariae, the content of effective components in radix Scutellariae is often low due to the influence of environment and genetic characteristics, and the quality of radix Scutellariae is seriously affected. The invention creatively regulates and controls the baicalin accumulation mode by changing the external environment condition of the baicalin by means of artificial water regulation, promotes the accumulation of baicalin in the baical skullcap root, and can obviously improve the content of active ingredients in the baical skullcap root medicinal material. Through a large number of experiments, the applicant finds that before 9 months, the harvesting period of the baikal skullcap root is not needed, the biomass of the baikal skullcap root does not reach the maximum value after the moisture regulation is implemented, the yield of the baikal skullcap root medicinal material is affected, and the biomass of the baikal skullcap root is basically stable in 9-10 months, and the yield of the baikal skullcap root can be ensured by the implementation of the moisture regulation. After the water content of the soil for cultivating the baikal skullcap root is monitored in 9-10 months of the next year, the water content of the soil is respectively at n
