[0025] 1, the preparation method of organic selenium nutrient solution

[0026] (1) Preparation of medium for cultivating yeast and probiotics:

[0027] The ratio of the raw materials used and the preparation is: to prepare 400kg of nutrient solution, 9kg of sugar, 29kg of corn flour or grass powder or flour, 12kg of animal blood or yogurt, 5g of VE for feed, 10g of yeast, and 350kg of local biogas slurry are required;

[0028] Use sugar, corn flour or grass powder or flour as the carbon source, animal blood or yogurt as the nitrogen source, adjust the carbon-to-nitrogen ratio (C / N) to 25:1, and add VE for feed at the same time;

[0029] (2) Add 350 kg of local biogas slurry to the culture medium, and add 10 grams of commercially available selenium-enriched yeast or brewer's yeast; Occurs naturally during cultivation;

[0030] (3) According to the ratio of adding 2 grams of sodium selenite per kilogram of culture medium, sodium selenite was added to the culture medium; after...

Abstract

The invention discloses a cultivation method of a selenium-enriched blueberry. The cultivation method comprises the following steps: (1) a selenium-enriched organic fertilizer is applied to a blueberry fruit tree before the tree blooms; (2) after the blueberry is picked, astragalus smicus is interplanted and harvested, the soil is cultivated; (3) organic selenium nutrient solution is sprayed when fruits are inflated. Selenium-enriched treatment is performed to the cultivated blueberry by adopting a foliar spray and root application method, and exogenous inorganic selenium can be changed into ecological organic selenium protein in an astragalus smicus interplanting process, thus the cultivation method is good for blueberry growth. The total selenium content of the fresh blueberry fruits is 0.048mg/kg, and the total selenium content of organic selenium reaches 85.6%; the zinc content is 2.4mg/kg; the anthocyanin content is 1548mg/kg, SOD (superoxide dismutase) in 100g fresh fruit includes 4.85 international units, and the VE (vitamin E) content is 86.4ug/kg.

Description

technical field [0001] The invention relates to a method for cultivating selenium-enriched blueberries. Background technique [0002] Selenium is one of the 14 trace elements known to be necessary for the human body. It is an important element of selenium-glutathione peroxidase. Taking selenium-containing foods can improve immunity, prevent cancer and fight cancer. The WHO organization recommends 50-200 micrograms per day. Due to selenium deficiency in 72% of the land in my country, the average daily intake of selenium is only 38 micrograms. Selenium intake from food is insufficient, and it is necessary to take selenium health food reasonably. In 2006, the China Selenium Supplement Association proposed that it is urgent to supplement selenium for all. For plants, selenium can antagonize the absorption of lead and cadmium and promote growth. [0003] Blueberry belongs to Rhododendronaceae Vaccinium, also known as lingonberry. Some people in China call it blueberry, which i...
