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

Abstract

The present invention discloses a planting method of iodine-enriched cabbage. Said method includes the following steps: (1), selecting high-quality cabbage seeds and soaking said cabbage seeds in warm water with 55 deg.C-56 deg.C for 15-16min; (2), making the soaked and sterilized cabbage seeds be uniformly spread on the seedling bed to make seedling cultivation; when 1-2 euphylises are grown from seedling, making gapping operation, when 6-8 euphylises are grown from seedling, making transplantation and setting plate; and (3), making field management, applying solid iodine organic fertilizer and applying liquid iodine fertilizer in different stages.

Description

technical field [0001] The invention relates to a planting method of iodine-rich cabbage. 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 "iodine deficiency disease" (IDD). [0003] According to epid...
