specific Embodiment approach 1

[0009] Specific embodiment one: present embodiment improves the method for the total flavonoid content in the hawthorn leaf of cold area to realize by the following steps: one, adopt wild mountain red as parent stock, graft with hawthorn scion then, select the surviving hawthorn scion grafting branch to cultivate for 3 years , and then the hawthorn scion grafted branches were removed for radiation; 2. The hawthorn scion grafted branches after radiation were re-scion-grafted on the 3-year-old wild Shanlihong rootstock, and the hawthorn scion grafted branches survived the next year to complete the total amount of hawthorn leaves in cold regions. Improvement of flavonoid content; wherein the dose of radiation in step 1 is 2000Gy, and the radiation source is cobalt 60.

[0010] In step 1 of this embodiment, the wild Sanlihong is wild high-quality Dayeshanlihong in the Greater and Lesser Khingan Mountains.

[0011] Scion grafting adopts existing conventional technology in the prese...

specific Embodiment approach 2

[0025] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the hawthorn variety selected for scion grafting in step one is Dajinxing or crooked red. Other steps and parameters are the same as those in Embodiment 1.

Abstract

The invention provides a method for improving the total flavonoid content in leaves of hawthorn trees in the arctic-alpine areas, and relates to the method for improving the total flavonoid in the leaves of the hawthorn trees. The invention solves the problem of low content of the total flavonoid in the leaves of the existing hawthorn trees in the arctic-alpine areas. The method comprises the following steps: 1, wild crataegus pinnatifida is adopted as mother stock, hawthorn scion is used for grafting, a viable grafted branch of the hawthorn scion is selected to be cultured for 3 years, and the viable grafted branch of the hawthorn scion is taken down for radiating; and 2, the radiated grafted branch of the hawthorn scion is grafted with 3-year wild crataegus pinnatifida stock once again, and the grafted branch of the hawthorn scion survives in the next year to complete improvement of the total flavonoid in the leaves of the hawthorn trees in the arctic-alpine area; and the dosage of radiation in the step 1 is 2,000Gy, and the radiation source is cobalt 60. The total flavonoid content in the leaves of the hawthorn trees in the arctic-alpine area is up to 10 to 41.2 percent, the hawthorn trees in the arctic-alpine area can normally grow in an environment with the temperature of -40-40 DEG C, and the livability rate of the hawthorn trees reaches 95 percent.

Description

technical field [0001] The invention relates to a method for increasing the total flavonoid content in the leaves of hawthorn. Background technique [0002] Hawthorn belongs to the genus Hawthorn in the family Rosaceae, also known as Hongguo and Shanlihong. Its fruit is sweet and sour and has the effects of digesting food, dispelling blood stasis, relieving pain, and repelling insects; It also contains vitexin, an anti-cancer drug component. [0003] At present, the content of total flavonoids in the leaves of hawthorn trees in cold regions is low, only 2.5% to 4.5%, which cannot meet the actual needs. Contents of the invention [0004] The invention aims to solve the problem of low content of total flavonoids in the leaves of hawthorn trees in cold regions, and provides a method for increasing the content of total flavonoids in the leaves of hawthorn trees in cold regions. [0005] The method for improving the total flavonoid content in the leaves of hawthorn trees in c...
