Problems solved by technology

[0004] Therefore, there are selenium fertilizer residues in the prior art, and the inorganic selenium content is high, thereby bringing about the problem of food safety risk; Soil pollution problem; In addition, the existing production of selenium-enriched rice technology is complex and labor-intensive problems, so there is an urgent need for a method that can effectively increase the content of selenium in rice, and can relatively reduce the loss of selenium fertilizer, and increase the amount of selenium. Fertilizer utilization rate, reduce production cost, no side effects on soil quality, effective and reasonable method for controlling selenium content in rice

Embodiment 1

[0032] Preparation of organic selenium-enriched foliar fertilizer:

[0033] (1) Take the required raw materials of each component according to the ratio of parts by weight: 55 parts of alcohol waste liquid and 4.5 parts of sodium selenite, and then dissolve sodium selenite; wherein, the alcohol waste liquid is produced by molasses or cassava The waste liquid produced in the alcohol process is obtained by evaporation and concentration, and the hammer of the waste liquid is ≥50°Bx;

[0034] (2) Slowly add the sodium selenite dissolved in step (1) into the alcohol waste liquid, while adding the sodium selenite solution, shake well; after adding, place the resulting mixed solution on the shaker Shake for 180 minutes, the shaking frequency is 100r / min, and the temperature is 30°C; the obtained organic selenium-enriched foliar fertilizer is used for later use.

Abstract

The invention discloses a method for producing selenium-enriched rice through green manure-rice rotation. The method comprises the following steps: (1) field selection; (2) green manure planting; (3) field turning up and green manure turning over; (4) soil preparation; (5) seed selection and seedling raising; (6) seedling transplanting; (7) field management; (8) rice harvest and storage. The method has the beneficial effects that the content of selenium in rice can be effectively increased under various soil conditions, the loss of selenium fertilizers can be relatively reduced and the selenium fertilizer utilization rate can be increased; soil pollution caused during selenium fertilizer application is avoided and the rice field fertility level can be improved; the traditional selenium-enriched rice planting flows are simplified, thus reducing the labor force input and the production cost.

Description

technical field [0001] The invention relates to a method for producing selenium-rich rice, in particular to a method for producing selenium-rich rice in green manure-rice rotation. Background technique [0002] Selenium is one of the essential nutritional elements for the human body. Many diseases in the body are related to selenium deficiency (such as Keshan disease, Kaschin-Beck disease, cancer, anemia, etc.), but excessive selenium intake has a toxic effect on the human body. Studies have shown that selenium in food less than 0.05mg / kg will cause selenium deficiency in the human body; more than 3-5mg / kg will cause poisoning; the safe range is between 0.1-0.36mg / kg. Food is the main source of selenium for the human body. Foods produced on selenium-rich soils have high selenium content, while foods produced on low-selenium soils often have low selenium content, so that they cannot meet human needs. Surveys show that more than 70% of the soil in China is deficient in seleni...
