Description
Technical Field
The invention belongs to the technical field of crop safety production, and particularly relates to an application of a selenium-increasing and cadmium-reducing complexing agent in rice planting.
Background
Rice is the main food crop in China, and the population taking rice as the staple food in China accounts for about 50 percent of the total population. The rice planting area in China reaches 2996 million hectares, and the distribution area is wide. Because of the historical reasons such as grain pressure, high yield is the target in the past in rice production in China, the attention degree on the content of vitamins and trace elements in rice is low, along with the increasing improvement of the living standard of residents and the development of external trade, the inherent quality and the nutritional value of grain crops are increasingly emphasized by people, and the nutritional and health-care rice which is safe to eat and functionalized becomes the urgent need of people at present.
Cadmium is a toxic heavy metal element, and can be gradually accumulated in systems such as liver, kidney, bone, lung and the like after entering a human body, so that the systems are damaged. The chronic cadmium poisoning symptoms are represented by fatigue, olfactory failure, hemoglobin reduction and the like, and people with severe poisoning can cause bone pain and even die due to other complications. Cadmium is listed as the first in 12 kinds of hazardous substances with global significance proposed by the environmental planning agency of the united nations in 1984. The rapid development of modern industries such as ore mining, metal smelting, chemical manufacturing and the like leads to the gradual increase of cadmium pollution of soil and water. Cadmium is reported to enter soil at present in the world as high as 2 million tons per year, and enrichment through the food chain will also threaten human health.
Selenium is an important trace element essential to humans and animals and is a component of glutathione peroxidase, which is essential for the biological metabolism of higher animals. Selenium deficiency of human body can cause diseases such as keshan disease, Kaschin-Beck disease and the like, and seriously affect human health. At present, selenium-rich agricultural products are effective ways for supplementing selenium elements to human bodies, but the selenium content in the current selenium-rich rice is still low, and the capacity of supplementing the selenium elements to the human bodies is limited.
