Example Embodiment

[0019] Example 1: The rice variety D You 11 (commercially available) was selected, and the selenium content in the soil was 0.51 mg / kg. Ziyunying was sown on September 11, 2006, with a seed rate of 1.5 kg / mu, and the soil was plowed and buried on April 25 of the following year; rice was sown on May 10, 2007, and transplanted on June 15. According to the management of organic planting regulations, the selenium content of rice (polished rice) is 0.15mg / kg.

Example Embodiment

[0020] Example 2: Xinliangyou 6 (commercially available) was selected as a rice variety, and the selenium content in the soil was 0.35 mg / kg. The previous crop of Astragalus vulgaris was sown on September 14, 2007, with a seed rate of 1.5 kg / mu. The soil was plowed and buried on April 28 of the following year; the rice was sown on April 23, 2008, and moved on June 1 Planting is managed in accordance with the standard organic planting method, and the measured selenium content of rice (polished rice) is 0.11mg / kg.

Example Embodiment

[0021] Example 3: The rice variety Hua'an 501 (commercially available) was selected, and the selenium content of the soil was 0.56 mg / kg. The previous crop of Astragalus vulgaris was sown on September 10, 2008, with a seed rate of 1.5 kg / mu, and the soil was plowed and buried on April 26 of the following year; rice was sown on May 5, 2009 and moved on June 15 The selenium content of rice (polished rice) is measured to be 0.17mg / kg.

Abstract

The invention discloses a cultivation method of organic selenium-enriched rice. The cultivation method comprises the following steps: a. selecting soil of which the selenium content is above 0.2mg/kg; b. planting astragalus smicus before rice planting, and taking the astragalus smicus as the base fertilizer for planting afterculture rice; and c. selecting good-quality rice variety, and carrying out cultivation management with an organic planting normative method to produce the organic selenium-enriched rice. The production of the organic selenium-enriched rice according to the above technical scheme can increase soil fertility and ensure that rice products reach the selenium-enriched standard, thereby guaranteeing environmental friendliness and safety of the rice products. When the method is applied in different varieties of rice and different soils of different selenium containing levels, the selenium content of rice is obviously improved. Detection proves that the selenium content of rice cultivated with the method is improved by above 100%.

Description

technical field [0001] The invention relates to the field of rice cultivation methods, in particular to an organic selenium-enriched rice cultivation method. Background technique [0002] Selenium has a wide range of uses, and has been praised as "the king of anti-cancer among trace elements", "the patron saint of the heart" and "the nemesis of viruses". Nowadays, the role of selenium in the prevention and treatment of Keshan disease, Kaschin-Beck disease and cretinism has been internationally recognized; the application of selenium in the prevention and treatment of cardiovascular and cerebrovascular diseases, diabetes and viral hepatitis has also attracted more and more attention; The important functions and effects of radiation protection, anti-aging, improving immunity, protecting eyesight and promoting reproductive health have also been confirmed. [0003] At present, there is no uniform standard for the human body's demand for selenium. The standard recommended by th...
