Problems solved by technology

[0005] Although Enshi Prefecture has two world-class resources, the only independent selenium deposit and the world's largest selenium-enriched biosphere, due to the uneven distribution of selenium resources, the selenium content in soil and water varies greatly, and the produced vine tea contains The amount of selenium is extremely unstable, and natural vine tea in most areas cannot meet the selenium-enriched standard
At the same time, due to the lack of standardized production, seedling resources are insufficient, the ability of seedling reproduction and supply cannot fully meet the needs of industrial development, and wild resources are over-harvested, leading to serious disorderly and over-exploitation

Embodiment 1

[0028] A kind of cultivation method of selenium-enriched vine tea, the steps are as follows:

[0029] a. Winter storage of cuttings: branch arrangement: in December, select branches after the leaves of vine tea have fallen, grade I branches: adopt perennial branches, stem diameter ≥ 0.5cm, stem length ≥ 40cm; grade II branches: perennial branches should be adopted, Stem thickness ≥ 0.3cm, stem length ≥ 40cm, stem thickness refers to the maximum diameter of the base of the cuttings of rattan tea, stem length refers to the maximum length of branches of rattan tea cuttings; branches must have no broken branches, dry branches, miscellaneous branches, branch requirements The color is normal, no quarantine harmful organisms; branch winter storage: when pruning, the upper end of the branch is 0.5cm away from the bud, cut into a 45-degree oblique mouth to prevent stagnant water, and the lower end is cut into a flat mouth that is conducive to more rooting. The length of the branch is gu...

[0037] Embodiment 2 A kind of cultivation method of selenium-enriched vine tea, the steps are as follows:

[0038] 1. Winter storage of cuttings

[0039] (1) Arranging branches. By December, after the leaves of the vine tea have fallen, the branches are selected. For grade I branches, perennial branches are suitable, with stem diameter ≥ 0.5cm and stem length ≥ 40cm; for grade II branches, perennial branches are suitable, stem diameter ≥ 0.3cm, stem length ≥ 40cm, stem thickness refers to the base of the cuttings of rattan tea The maximum diameter of the stem length refers to the maximum length of the cutting branches of vine tea. The purchased branches must be free of broken branches, dry branches and miscellaneous branches. The branches are required to have normal color and no quarantine pests.

[0040] (2) The branches are stored in winter. When pruning, the upper end of the branch is 0.5 cm away from the bud and cut into a 45-degree oblique mouth to prevent stagnant w...

Abstract

The present invention provides a cultivation method for selenium-enriched ampelopsis grossedentata. The method is characterized by comprising the following steps: a, winter storage of cutting branches; b, garden preparation; c, cutting; d, field management; e, fertilization; f, prevention and control of main diseases and pests; g, harvesting; and h, storage. According to the cultivation method forthe selenium-enriched ampelopsis grossedentata provided by the present invention, a seedling raising step is reduced, straight cutting garden construction is adopted, the efficiency is improved, theproduction cost is reduced, and the picking time of the one-year ampelopsis grossedentata is increased; and the survival rate of branches is improved from the seedling raising survival rate of 40-50%to 85% or more, the selenium content achieves a selenium-enriched standard, the added value of the ampelopsis grossedentata can be improved, and the market competitiveness can be enhanced.

Description

technical field [0001] The invention relates to a cultivation method of selenium-enriched vine tea. Background technique [0002] Vine tea, commonly known as Dragon Boat Festival Tea, Longevity Vine, Tengpo Tea, Dragon Beard Tea, is the tender stems and leaves of Snake Grape in the family Vitis genus. Vine tea is mainly distributed in Guangdong, Guangxi, Hunan, Jiangxi, Fujian, Yunnan, Guizhou and other provinces and regions south of the Yangtze River Basin in my country. Neivine tea plants in Hubei Province are mainly distributed in the mountainous area of ​​southwestern Hubei, especially in Laifeng County of Enshi Prefecture. Vine tea, in addition to the distribution of the tooth snake grape (vine tea) in this area, there are also plants of the same family and genus, the big-leaf snake grape and the light-leaved snake grape. Vine tea contains a large amount of flavonoids, the main substance of which is dihydromyricetin, which has a scavenging rate of 73.3%-91.5% for free r...
