How do you think selenium-enriched functional agriculture can be done well?

It is generally believed that selenium-enriched agriculture can be called selenium-enriched agriculture by using the advantages of selenium resources in natural selenium-enriched areas to produce selenium-enriched agricultural products. But this is just a narrow and one-sided view. First of all, selenium-enriched agriculture not only exists in natural selenium-enriched areas, but also can be enhanced by exogenous selenium nutrition in selenium-deficient areas with the progress of agricultural science and technology. Secondly, selenium-enriched agricultural production needs to use biological or non-biological means to make agricultural products contain selenium, and the selenium content in the produced agricultural products needs to meet the requirements of relevant selenium-enriched standards.

Selenium-enriched agriculture refers to the agricultural production mode of engaging in the production and management of natural selenium-enriched agricultural products in natural selenium-enriched areas of soil or using biotechnology to add and transform exogenous selenium in selenium-deficient areas of soil, so that the selenium content of agricultural products can meet the requirements of selenium-enriched standards. In natural selenium-enriched areas, plants can use selenium resources in soil and accumulate selenium content in plant agricultural products through biotransformation; In selenium-deficient areas, selenium content in plant agricultural products can be accumulated by applying selenium fertilizer to crops; By feeding selenium-enriched feed, the selenium content in poultry and other animals can be accumulated, so as to develop selenium-enriched aquaculture; Selenium-enriched food (beverage) is produced by selenium-enriched nutritional fortifier in food production.

Selenium-enriched agriculture is a kind of modern agriculture and belongs to the category of functional agriculture. Agricultural development can be divided into three stages: high-yield agriculture, green agriculture and functional agriculture. At the beginning of the founding of New China, food was in short supply. It was regarded as the primary task of agricultural development in China to realize high-yield agriculture by improving soil, applying chemical fertilizers and pesticides and developing improved varieties. From 65438 to 0989, "green agriculture" was introduced into China, and green agriculture in a broad sense included pollution-free agriculture, green agriculture and organic agriculture. As the third stage of agricultural development, functional agriculture pays attention to the healthy connotation of agricultural products. With the continuous improvement of people's living standards and people's awareness of nutrition and health care, we should not only eat safely, but also eat healthily. China's agricultural products will eventually become nutritious and functional, and selenium-enriched functional agricultural products just meet people's consumption needs. At present, China agriculture has already ushered in the third stage of agricultural development (functional agriculture). Selenium-enriched agriculture is one of the earliest development directions of functional agriculture and has broad development prospects.
