Description

Nutrient solution for cultivation of herba cynarae scolymus and cultivation method Technical Field The invention relates to the technical field of plant cultivation, in particular to a nutrient solution for cultivation of herba cynarae scolymus and a cultivation method. Background Herba plantaginis is a species under the genus of the branch of the dicotyledonous plant, the lithospermaceae and the genus of the cynara, and the herba plantaginis seed oil of the herba cynarae scolymus is rich in omega-3 long-chain polyunsaturated fatty acids, including n-3 polyunsaturated fatty acids and high content of rare fatty acids glycyrrhizic acid and stearidonic acid, and the fatty acids have been proved to be helpful for reducing the risk of cardiovascular diseases, regulating inflammation and immune response, improving brain development and vision of infants, improving age-related degenerative diseases, regulating depression and mood disorder, and have important health care and medical values. In order to realize large-scale and standardized planting, the cultivation and seedling raising is a key link for acquiring the herba cynarae sonchifolia. At present, in the research of plant seedling, the formula of the Hoagland nutrient solution is the most widely applied in scientific research and agriculture, and the composition of the Hoagland nutrient solution is continuously changed along with the continuous and intensive research and development of the plant nutrient solution. However, when the Hoagland nutrient solution is adopted to grow seedlings of the echium, tomatoes, watermelons and other crops, the existing nutrient solution can promote early and rapid growth of the plantain leaf echium seedlings, but the high-foot and weak seedling phenomenon is easy to occur, the survival rate is very low when the plantain leaf echium seedlings are transplanted to the field, the robustness of the seedlings is affected, and the survival rate is remarkably reduced. Therefore, the nutrition liquid formula capable of effectively promoting the growth of the long plant, the leaves and the strong stems of the cynara scolymus and coordinating the whole and balanced growth is provided, and the efficient and robust cynara scolymus seedling cultivation is a problem to be solved at present. Disclosure of Invention In order to overcome the defects of the prior art, the invention aims to solve the problem of low survival rate of the plantain leaf and thistle seedling, effectively promote the integral growth of the plantain leaf and thistle seedling, and efficiently cultivate the plantain leaf and thistle seedling with developed root systems and strong plant types, thereby remarkably improving the survival rate of transplanting. In order to achieve the above purpose, the invention provides a nutrient solution for cultivation of herba plantaginis and herba cynarae scolymus, which comprises Hoagland nutrient solution, auxin and plant growth retardant, wherein the concentration of the auxin is 0-0.01 mg/L, and the concentration of the plant growth retardant is 0.005-0.01 mg/L. Preferably, the auxin concentration is 0.005mg/L. Preferably, the concentration of the plant growth regulator is 0.01mg/L. Preferably, the auxin comprises one of naphthalene acetic acid or indolebutyric acid. Preferably, the plant growth retardant comprises one of mepiquat chloride, paclobutrazol or chlormequat chloride.
