Embodiment 1

[0030] In a radish planting base, before plowing the vegetable field, the nano-selenium plant nutrient was evenly spread on the surface of the vegetable bed at an amount of 0.5 kg per mu, and the above-mentioned vegetable bed was plowed so that the nano-selenium plant nutrient was evenly distributed on 25 In the plow layer of more than 1 cm, it should be leveled after plowing; the radish should be transplanted into the above-mentioned vegetable bed, and related water and fertilizer management should be carried out according to the normal planting method.

[0031] When the radish was mature, the radish samples were collected for the test of total selenium content and selenium content. The results show that the selenium content in radish is about 10 micrograms / kg, and the organic selenium content is about 9.6 micrograms / kg, accounting for about 96% of the total selenium.

Embodiment 2

[0033] In a radish planting base, before the vegetable field is plowed, the nano-selenium plant nutrient is mixed with the base's own fertilizer (organic fertilizer and compound fertilizer, etc.) according to the amount of 0.4 kg per mu, and then spread on the surface of the vegetable bed. The vegetable bed is plowed, so that the nano-selenium plant nutrient is evenly distributed in the plow layer above 25 cm, and it is leveled after plowing; the radish is transplanted into the above-mentioned vegetable bed, and the relevant water and fertilizer management is carried out according to the normal planting method.

[0034] When the radish was mature, the radish samples were collected for the test of total selenium content and selenium content. The results show that the selenium content in radish is about 40 micrograms / kg, and the organic selenium content is about 38 micrograms / kg, accounting for about 95% of the total selenium.

Embodiment 3

[0036] In a radish planting base, before plowing the vegetable field, the nano-selenium plant nutrient was evenly spread on the surface of the vegetable bed at an amount of 0.7 kg per mu, and the above-mentioned vegetable bed was plowed so that the nano-selenium plant nutrient was evenly distributed on 25 In the plow layer of more than 1 cm, it should be leveled after plowing; the radish should be transplanted into the above-mentioned vegetable bed, and related water and fertilizer management should be carried out according to the normal planting method.

[0037]When the radish was mature, the radish samples were collected for the test of total selenium content and selenium content. The results show that the selenium content in radish is about 70 micrograms / kg, and the organic selenium content is about 65 micrograms / kg, accounting for about 93% of the total selenium.

Abstract

The invention discloses radishes rich in organic selenium and a production method thereof. The radishes rich in organic selenium have an organic selenium content of 8-400 microgram / kg, with organic selenium accounting for over or equal to 80 percent of the total selenium content. The method comprises the following steps: before vegetable land plowing, separately scattering a certain amount of nano-selenium plant nutrient onto the surfaces of vegetable ridges and then plowing, or uniformly scattering the nano-selenium plant nutrient onto the surfaces of vegetable ridges after fully mixing the nano-selenium plant nutrient with other conventional fertilizer and plowing the fertilizer into the plough layer as base fertilizer, and then transplanting and cultivating radishes. The invention have the advantages that the radishes are rich in selenium, the overall selenium content is uniform, and the ratio of organic selenium in the method is improved, thereby solving the problem of selenium content stability in different batches of radishes in the prior art, ensuring uniform selenium content in the radishes, and realizing standardized scale production.

Description

technical field [0001] The invention relates to a selenium-enriched vegetable, in particular to an organic selenium-rich radish and a production method thereof, which belong to the technical field of agronomic planting of agricultural products and agricultural fertilization. Background technique [0002] Selenium is an essential trace element for humans and animals. It has biological properties such as scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, enhancing immunity, and antagonizing heavy metals. The daily selenium intake recommended by the Chinese Nutrition Society is 50~ 250μg. The source of selenium in the human body mainly depends on dietary intake, but the average daily selenium intake of adults in my country is only about 36μg. The country belongs to low-selenium or selenium-deficient areas. Selenium-enriched agricultural by-products are an effective way for the human body to supplement selenium. Therefore, selenium-enriched technology is a hot area...
