Embodiment 1

[0032] Under soil cultivation conditions, sodium selenite is mixed with a certain amount of slaked lime at the seedling stage of the pot-pot crushed catkins to obtain a mixture of pH 7-8, and it is applied to the soil where the pot-pot crushed catkins grows, The average selenium content in the plow layer soil for its growth is 0.1mg / kg. When harvesting, the broken rice chestnut plants are collected to test the selenium content. The total selenium content is about 0.2mg / kg. Wherein, the selenium Selenium in the form of methionine accounts for about 90%.

[0033] Under hydroponic conditions, adjust the pH of the culture medium of the broken rice chestnut in the pot to 7-8, and mix sodium selenite and sodium selenate with any amount and add it to the culture medium, so that the average selenium content in it is 0.1mg / kg, when harvested, the pot-pot crushed Camelina plants were collected to test the selenium content. The total selenium content was about 0.5 mg / kg, and the seleniu...

Embodiment 2

[0037] Under soil cultivation conditions, sodium selenate is mixed with a certain amount of sodium hydroxide to obtain a mixture of pH 7-8 before the bolting of the pot-pot broken rice chestnut, and it is applied to the soil where the pot-pot crushed rice chestnut grows , the average selenium content in the plow layer soil where it grows is 0.5mg / kg, and when harvesting, the broken rice chestnut plants in pots and bottles are collected to test the selenium content, and the total selenium content is about 1.0mg / kg, wherein, selenium Selenium in the form of methionine accounts for about 90%.

[0038] Under hydroponic conditions, the pH of the culture medium was adjusted to 7.5 before the bolting of the broken rice chestnuts in the pot bottle, and sodium selenite, sodium selenate, and selenoamino acids were mixed in any amount and added to the culture medium to make the selenium The average content is 0.5mg / kg. When it is harvested, the selenium content is tested by collecting th...

Embodiment 3

[0042] Under soil cultivation conditions, sodium selenite is mixed with a certain amount of potassium hydroxide to obtain a mixture of pH 7-8 at the seedling stage of the pot-pot crushed catkins, and it is applied to the soil where the pot-pot crushed catkins grows Among them, the selenium content in the plow layer soil where it grows is an average of 5mg / kg. When harvesting, the potted rice chestnut plants are collected to test the selenium content. The total selenium content is about 20mg / kg. Among them, the selenium Selenium in the form of methionine accounts for about 90%.

[0043] Under hydroponic conditions, the pH of the culture medium is adjusted to 8 before the bolting of the potted rice chestnut, and sodium selenite, sodium selenate, and selenoamino acid are mixed in any ratio and added to the culture medium to make the selenium The average content is 5mg / kg. When it is harvested, the potted rice chestnut plants are collected to test the selenium content. The total s...

Abstract

The invention discloses a selenium-enriched cardamine hupingshanesis plant material and a cultivation method for the same, wherein selenium in the plant material exists in the form of selenocysteine, and the content of the selenium in the form of selenocysteine in the plant material is 0.2-20000 mg / kg and occupies more than 90% of the total content ratio of selenium. The selenium-enriched cardamine hupingshanesis plant material is cultivated according to a conventional method, wherein the conventional method comprises the following steps of: adding a selenium source in the growth medium of cardamine hupingshanesis during the growth cycle of the cardamine hupingshanesis; adjusting the content of selenium in the growth medium to achieve 0.1-1000 mg / kg; and adding alkaline substances simultaneously to keep the pH value of the overall or local environment of the growth medium in a range from 7 to 8. The material can be used as good selenium source supplementary substance for human body and animals, and directly eaten or used as selenium-enriched food or selenium-enriched feed beneficial to the health of human and animals.

Description

technical field [0001] The invention relates to a selenium-enriched plant material, in particular to a selenocysteine-rich broken rice chestnut plant material and a cultivation method and application of the material, which belong to the field of cultivation technology. technical background [0002] Selenium is an essential trace element in humans and animals. It is the active center of up to 23 functional proteins such as glutathione peroxidase (GSH-Px) and selenoprotein P. It has anti-cancer, anti-oxidation, and immune-enhancing properties. power etc. About 72% of our country's daily intake of selenium is significantly lower than the daily selenium intake recommended by the World Health Organization (WHO), resulting in serious human and animal health problems. [0003] Selenium is generally divided into two categories: inorganic selenium and organic selenium: the former includes selenate, selenite, etc. Inorganic selenium is poorly absorbed by humans and animals, and has a...
