Problems solved by technology

[0002] Coptis chinensis is an annual aquatic herb that blooms from July to August and bears fruit from August to September. Its fruit is used in traditional Chinese medicine to invigorate the spleen, kidney, and astringent essence. At present, heavy metal pollution in the environment is becoming more and more serious, and cadmium is the first inorganic pollutant. , the absorption of cadmium in the growth of Coptis chinensis will lead to growth retardation, lower yield and lower quality, which will affect the medicinal ingredients and effects, and after eating, cadmium will enter the human body and endanger human health. Therefore, measures need to be taken to prevent the absorption of cadmium by Coptis chinensis. However, The pH value of the optimal production environment for Coptis chinensis is 5.5-6.5, and the pH value needs to be increased to prevent the absorption of cadmium, which will affect the growth of Coptis chinensis. Therefore, we propose a method to prevent and control the pollution of cadmium in Chinese medicine Coptis chinensis to solve the above problems

Embodiment approach

[0024] The present invention provides an embodiment: a method for preventing and controlling cadmium pollution of Chinese medicine Coptidis Rhizoma, comprising the following steps:

[0025] (1) topdressing cultivation

[0026] Cultivate from September to October of this year, topdressing in the spring of the second, third, fourth, and fifth years, and topdressing once in the second, third, and fourth autumn (September-October) after seed collection and transplanting, for a total of eight times top dressing;

[0027] (2) Transplanting soil

[0028] After the second, third, and fourth autumn (9-10 months) topdressing after transplanting in step (1), the cadmium inhibitor and control agent is used to cultivate the soil, and the spraying amount of the cadmium inhibitor and control agent is 75-100Kg / mu;

[0029] In step (1), the topdressing material is farm manure: calcium superphosphate is mixed at a weight ratio of 5:1, and topdressing is carried out at an application rate of 2...

Abstract

The invention discloses a method for prevention and control of cadmium contamination of traditional Chinese medicine rhizoma coptidis. The method includes steps: (1) performing topdressing from September to October in the current year of rhizoma coptidis planting and in May in the second, third, fourth and fifth years, and after transplanting, performing topdressing once in autumn (September-October) in the second, third and fourth year, wherein topdressing is carried out for eight times to promote growth and activity of rhizoma coptidis and lays a foundation for prevention and control of cadmium absorption; then, after topdressing in autumn (September-October) in the second, third and fourth year after transplanting in the step (1), performing earth-up operation by adopting a cadmium blocking agent, wherein a spraying quantity of the cadmium blocking agent is 75-100Kg / mu, chelation of the cadmium blocking agent with cadmium in soil is realized, cadium absorption of rhizoma coptidis isreduced, stress resistance of rhizoma coptidis is improved, the self-protection performance of rhizoma coptidis is improved, plasma membrane damages of roots and leaves under cadmium stress are reduced, antioxidant enzyme activity of the leaves under cadmium stress is improved, the antitoxic performance of rhizoma coptidis is improved, system immunity is enhanced, cadmium accumulation is inhibited, and prevention and control of cadmium contamination are realized.
