Mulberry management method for improving mulberry leaf flavone content

Abstract

The invention belongs to the technical field of mulberry cultivation, and particularly relates to a mulberry management method for improving the mulberry leaf flavone content. The method comprises thefollowing steps that after harvesting of mulberries is ended, dead leaves, old leaves and ill leaves are pruned, and leaf surfaces are sprayed with nutrient solution successively two times, wherein the interval time is 7-9 days; the leaf surfaces are sprayed with the nutrient solution for the third time 2-4 days before frost. The mulberry management method effectively promotes activity improvement of related enzymes of various types in the synthetic process of flavonoid compounds in the mulberry leaves, accordingly improves the conversion efficiency of the enzymes, further promotes synthesisand accumulation of flavonoids, effectively improves the photosynthesis efficiency, makes the metabolism of the mulberry leaves vigorous, promotes carbon and nitrogen metabolism, effectively avoids damage to mulberry leaf tissue structures due to change of external environment and accordingly avoids damage to original flavonoids, so that the flavonoids are synthesized gradually and are high in stability, the health care value of mulberry leaves is effectively improved, and the mulberry management method promotes comprehensive development and utilization of the mulberry leaves.

Description

Technical field [0001] The invention belongs to the technical field of mulberry cultivation, in particular to a mulberry management method for increasing the content of mulberry leaf flavonoids. Background technique [0002] Mulberry leaves are the leaves of the genus Morus of the Moraceae family. They are cultivated and produced in most regions of China. The main mulberry producing areas in the south are Jiangsu, Zhejiang, Anhui, Sichuan and other provinces. As a kind of wind-heat medicine, mulberry leaves are used in China and It is widely used in some other countries; mulberry leaves are bitter, sweet and cold, and return to the lung and liver meridian. It has the effects of dispersing wind and heat, clearing the lungs and moisturizing dryness, calming the liver and improving eyesight, and cooling blood to stop bleeding. It is often used to treat wind-heat, cold and warm At the beginning of the illness, symptoms such as lung heat and dry cough, throat swelling, throat swelling...

Problems solved by technology

[0002] Mulberry leaf is the leaf of Moraceae Morus plant, and it is cultivated and produced in most areas of China. The main producing areas of sericulture in the south are Jiangsu, Zhejiang, Anhui, Sichuan and other provinces. It is widely used in other countries; mulberry leaves are bitter, sweet, and cold, and return to the lung and liver meridian. At the beginning of the disease, lung heat and dry cough, throat fever, sore throat, toothache, red eyes, swelling and pain, eye tears, liver yang dizziness, dim eyesight, bleeding, spontaneous sweating, night sweats, wind fever and other symptoms; modern pharmacological research shows that, Mulberry leaves have various activities such as hypoglycemic and lipid-lowering, anti-oxidation, anti-tumor, etc. In recent years, studies on the chemical components of mulberry leaves have shown that mulberry leaves contain flavonoids, alkaloids, phenylpropanoids, organic acids, sterols, etc. Flavonoids are one of the important active ingredients of mulberry leaves, which have anti-aging effects and antibacterial activities, can inhibit lipid oxidation, cholesterol absorption, lower blood pressure, prevent arteriosclerosis, and Anti-cancer, but at present there is little research on flavonoids in mulberry leaves, and even few studies have been done on the method of increasing its flavonoid content, which inhibits the comprehensive development and utilization of mulberry leaves; Content method is a breakthrough for the field of mulberry leaves
