Method for cultivating iodine-enriched vegetables

Abstract

The invention discloses a method for cultivating iodine-enriched vegetable. According to the method, the iodine-enriched vegetables can be cultivated directly; iodine background contents in soil and surrounding environments can be increased; ecologic environments of iodine-deficient areas can be improved; and iodine contents in a food chain can be increased. The method disclosed by the invention makes use of biogeochemistry transfer theories, makes iodine-enriched seaweeds into a solid iodine organic fertilizer or a liquid iodine fertilizer, and can be used to cultivate the iodine-enriched vegetables through soil application or spraying application of the fertilizers.

Description

technical field [0001] The invention belongs to the field of cultivation of vegetables, in particular to a cultivation method of iodine-rich vegetables Background technique [0002] Iodine is an essential trace element for the human body. It plays an extremely important role in the metabolic process of the human body. More than one-third of the iodine in the human body exists in the form of the thyroid gland. Without iodine, the thyroid gland cannot synthesize thyroxine. It has biological functions such as promoting protein synthesis, regulating energy conversion, accelerating growth and development, and maintaining the structure of the central nervous system. Therefore, iodine deficiency in the human body will lead to a series of physiological disorders and abnormal biological functions, especially when babies are iodine deficient during growth and development. It can cause intellectual disability, and the overall impact on the human body due to iodine deficiency is called ...

Problems solved by technology

However, it has also been exposed in practice for many years that there are some obvious defects in this measure: the one is that the inorganic iodine added in table salt is volatile, and part of the iodine will be lost during storage, transportation and cooking, so the concentration of iodine added in table salt is very low. In addition, there are obvious individual differences in the absorption of inorganic iodine in salt by the human body, so that it is difficult to quantitatively evaluate its biological effectiveness; second, the iodine in the organism has the characteristics of double thresholds, that is, high iodine or low iodine Iodine will have different properties and different degrees of biological effects on the body. High iodine intake can also cause disease. People of different ages and categories (such as children, adults, pregnant women and nursing mothers) have a large daily demand for iodine. The difference is that the national salt iodization is implemented to supplement iodine for people who are really iodine deficient, but also forcibly supplement iodine for people who are not deficient in iodine, and even a small number of people who have excessive iodine intake. The incidence rate of high iodine disease has increased due to excessive intake of iodine, and it is spreading; third, in areas with severe iodine deficiency, once iodized salt is stopped, the prevalence rate of IDD will increase, which shows that adding iodine to table salt is a kind of Temporary rather than permanent and fundamental measures to improve iodine deficiency
