Problems solved by technology

[0002] Pueraria lobata is widely distributed in China and is rich in resources. It has the functions of relieving muscle and reducing fever, promoting body fluid, promoting rash, promoting yang and relieving diarrhea, etc. The main components are isoflavones, such as daidzin, daidzein, puerarin, triterpenoids, Coumarins, etc., the active ingredient is puerarin, the chemical name is 8-β-D glucopyranose-4', 7 dihydroxy isoflavones, and it is usually excavated from the end of November to the next March. It is 2-4 years old Radix Puerariae, because of its anti-inflammatory and antipyretic effects, expansion of coronary blood vessels, increase of coronary blood flow, reduction of myocardial oxygen consumption, improvement of myocardial contractility, and promotion of blood circulation, is suitable for coronary heart disease, angina pectoris, myocardial infarction, retinal artery Vein occlusion, sudden deafness and other diseases have remarkable curative effects, and have been widely used in health food, becoming a kind of plant with the same source of medicine and food. The existing kudzu root cultivation includes traditional planting methods and dense planting high-yield cultivation. 600-800 plants will be excavated in the second winter, and the yield and benefit will be low; dense planting and high-yield cultivation can plant 1,200 plants per mu, and the average yield per mu can reach 1,800kg, which has significantly improved the yield compared with traditional methods, but large-scale production At the same time, due to the large amount of chemical fertilizers used, the quality of kudzu root will be affected to a certain extent, and the content of total flavonoids in kudzu root is greatly affected by the place of origin and harvest season of kudzu root. Therefore, a considerable part of kudzu root cannot meet the medicinal needs

Embodiment 1

[0017] A planting method for improving the total flavonoid content of Pueraria lobata, comprising the following content:

[0018] (1) The cuttings are raised in the seedling bed, and the bed soil of the seedling bed includes the following raw materials in parts by weight: 36 parts of sandy soil, 8 parts of loess, 4 parts of borax, 10 parts of coconut peat, 2 parts of pure nitrogen, and 5 parts of modified hexacyclic stone powder ; Transplant with 1000 plants per mu after completion of seedling cultivation;

[0019] The preparation method of the modified hexacyclic stone powder is to pass through a 60-mesh sieve after pulverizing the hexacyclic stone to obtain powder, and the powder is 60 Irradiate in a Co-γ-ray irradiator with a total irradiation dose of 22kGy. After the irradiation is completed, soak in water at a temperature of 50°C for 15 minutes, filter and dry in a drying oven at a temperature of 85°C to reach the water content. Less than 8%;

Abstract

The invention belongs to the technical field of medical pueraria lobata planting, and particularly relates to a planting method for improving the content of total flavone in pueraria lobata. The planting method comprises seedling bed soil preparation and pre-picking management. Compared with the prior art, the planting method for improving the content of the total flavone in the pueraria lobata has the advantages that the seedling bed soil in the seedling stage and the management in the planting stage are adjusted appropriately, the nutritional growth and leaf development can be effectively promoted, and the planting method is helpful for the synthesis of flavone; compared with an existing planting technology, the content of the total flavone in the pueraria lobata can be improved while the yield is ensured, thereby conforming to the stipulation of the Chinese pharmacopoeia.
