Abstract

The invention provides a medicinal chrysanthemum fertilization method. The medicinal chrysanthemum fertilization method comprises the following steps: (1) applying 3-5 kg of ammonium sulfate and 1.5-2 kg of potassium phosphate into each mu of a field, and transplanting cutting seedlings into the field; (2) pinching for the first time when the seedlings are 25 cm in height, pinching for the second time after 15-20 d, then pinching for the third time after 15-20 d, and spraying 200-300 g of a calcium-magnesia phosphate fertilizer mixed with 30-50 kg of water once onto plant leaves per mu respectively after the second-time and third-time pinching; (3) after squaring, spraying 200-300 g of a leaf fertilizer mixed with 30-50 kg of water, as well as 150-200 g of potassium sulfate mixed with 20-50 kg of water, once onto the plant leaves per mu every 8-10 d. The medicinal chrysanthemum fertilization method can greatly increase the contents of chlorogenic acid and flavonoids in the medicinal chrysanthemum.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for fertilizing medicinal chrysanthemums. Background technique [0002] Chrysanthemum is the dry flower head of Chrysanthemum morifolium Ramat, a perennial herb of the Compositae family. It is a commonly used traditional Chinese medicine in clinical practice. It has the effects of dispelling wind, clearing away heat, improving eyesight, and detoxifying. . Chrysanthemum mainly contains various components such as volatile oil, inulin, amino acid, flavonoids and chlorogenic acid, among which total flavonoids and chlorogenic acid are the main active components. Total flavonoids have the effects of lowering blood pressure, dilating coronary arteries, and preventing coronary atherosclerosis. They are clinically used to treat hypertension and coronary heart disease. Chlorogenic acid has anti-inflammatory, anti-oxidation, coronary expansion, lipid-lowe...
