Description
Technical Field
The invention belongs to the technical field of agricultural product development, and particularly relates to selenium-rich highland barley germinated rice and a preparation method thereof.
Background
Selenium is a trace element necessary for human and animal health, has biological characteristics of free radical removal, oxidation resistance, aging delay, cancer resistance, immunity enhancement, heavy metal antagonism and the like, has various pharmacological effects of cancer resistance, heart and liver protection, immunity enhancement, aging delay, reproductive function enhancement and the like, is praised as 'vital fire', 'king of cancer resistance' and 'heart guard' by scientists, and the immunity is greatly reduced and the risk of infecting various highly pathogenic viral diseases is obviously increased due to the selenium deficiency of human bodies. In 1988, the Chinese Nutrition society lists trace element selenium as one of dietary nutrients which must be taken by residents in China every day, and recommends that the daily selenium intake is 50-250mg, but the average daily selenium intake of adults in China is only about 36 mg.
Selenium sources of human bodies are mainly ingested by diet, and selenium-rich agricultural and sideline products are effective ways for supplementing selenium elements to human bodies, so that the development of selenium-rich agricultural products is a hot spot field for research and development of scientists. Since selenium is associated with metal sulfides in the earth crust and exists in the form of rocks, although selenium in the rocks cannot be absorbed by crops, the selenium in the rocks can be converted into oxides through weathering, erosion, physical, chemical, microbial and other actions, and then the oxides are washed into soil to form various forms of selenium, such as elemental selenium, organic selenium, selenite, selenate and the like. Selenium in soil can be divided into: selenate, selenite, elemental selenium, and selenide; according to the binding type, the method can be divided into: soluble state and weak adsorption state, exchangeable state, carbonate binding state, iron manganese oxide binding state, organic matter binding state, residue state and the like. Selenium in different valence states and different combination states has different migration and transformation capacities in soil and different effectiveness on plants, so that the effective selenium content in the soil is a key factor determining the selenium content in the plants rather than full selenium. The effectiveness of selenium is influenced by soil total selenium, soil texture, soil pH, Eh, organic matter, etc., wherein soluble, exchangeable and carbonate bound selenium is most effective for crop absorption.
About two thirds of areas in China belong to internationally recognized selenium-deficient areas, wherein nearly one third of areas belong to serious selenium deficiency, so that 70% of people live in the selenium-deficient areas in China, and especially, keshan disease and Kaschin-Beck disease patients in certain areas in Tibet are caused by long-term selenium deficiency in the living areas. According to the investigation of the selenium content in the soil of the Tibet region, the total selenium content in the soil of the Tibet region is low, and the selenium content is regularly distributed in strips. However, in the area of the south of bujiang in Yaluzang, most areas of the south of the mountain, the first line of Yadong county, Baba county, Karma county, Jiangzui county and Lanka county of the selenium-rich area of Chuchu river, and the areas of the Ritudinian county and Zadao county in the Ali area in the west, the total selenium content in the soil is more than twice of the total selenium content in the soil of other areas in Tibet, and the standard of the medium-selenium soil can be achieved. Therefore, the development of selenium-rich products in Tibet areas becomes possible, and on one hand, the selenium nutrition level of Tibetan residents can be safely and effectively improved; on the other hand, the development of selenium-rich agricultural and livestock products is increased under the ecological environment of the clean soil in Tibet, and the product quality and the market competitiveness are improved.
However, the current investigation aiming at the total selenium content in the soil of the Tibet region is not accurate enough to find out the regional distribution position of the selenium-containing soil in the main agricultural region of the Tibet, and on the other hand, the unique geographical environment and climate of the Tibet region also influence the effective selenium content in the soil. Therefore, how to effectively improve the content and the state of effective selenium in the soil in the Tibet region and further develop selenium-rich agricultural products with Tibet characteristics can provide solid technical support for the construction of plateau ecological selenium cereals in Tibet and has important practical significance and necessity for accelerating the industrialization process of Tibet farming and animal husbandry. Therefore, the development of different selenium-rich highland barley agricultural products has positive significance for promoting the development of agricultural products in Tibet regions.
