Method for planting selenium-enriched organic tea

Abstract

The invention discloses a method for planting selenium-enriched organic tea, and belongs to the technical field of agricultural planting. The method comprises the following specific step of S1, land selection and preparation, wherein firstly, people can select a corresponding planting land area according to the planting area required for tea trees, then the selected planting land is ploughed, during ploughing, a ploughing machine can be adopted for turning soil out at the portion 30-40 cm below the soil, and then the soil which is turned out is crushed. By means of the method for planting theselenium-enriched organic tea, the principle that the capability of absorbing hexavalent selenium ions by tea saplings is high and the capability of absorbing tetravalent selenium ions by leaves of the tea saplings is high is well utilized, corresponding selenium fertilizers are applied to the roots and leaves of the tea saplings respectively, the full absorption of the selenium fertilizers by thetea saplings can be promoted, the purpose that the tea saplings can well absorb the selenium fertilizers by accurately and efficiently utilizing the organic selenium fertilizers is achieved, and thecontent of selenium in the organic tea is greatly increased, which is very beneficial for people to drink the organic tea to supplement selenium.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a planting method of selenium-enriched organic tea. Background technique [0002] Organic tea is a kind of tea produced and processed according to the method of organic agriculture. It is a kind of pollution-free and pure natural tea. The production of food additives and other substances conforms to the standards of the International Federation of Organic Agriculture Movements (LFOAM). Organic tea is also the first organic food certified for export in China. In recent years, more than 20 tea production units in China have obtained organic tea certificates. Established an organic tea base of nearly 6,000 mu. The annual production of organic tea has reached more than 500 tons (mainly green tea, some black tea, oolong tea, etc.). The cultivation methods of organic tea are divided into organic cultivation and quasi-organic cultivation. Organic cultivation does not use ...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a planting method of selenium-enriched organic tea, which solves the problem that it is difficult to control the content of selenium by directly using selenium ore powder, which can easily lead to excess selenium and inhibit the growth of tea seedlings At the same time, because the roots of tea seedlings have a strong ability to absorb hexavalent selenium and selenium ions, and the leaves of tea seedlings have a strong ability to absorb tetravalent selenous ions, the direct application of selenium ore powder is not conducive to the absorption of tea seedlings, and it is impossible to realize the absorption of tea saplings. The roots and leaves of the saplings are respectively applied with corresponding selenium fertilizers to promote the absorption of selenium fertilizer by the tea saplings. It is impossible to achieve the purpose of using organic selenium fertilizers accurately and efficiently so that the tea saplings can absorb selenium fertilizers well, thereby greatly reducing Solved the problem of selenium content in organic tea
