Method for cultivating radish containing natural iodine

Abstract

The invention discloses a cultivation method of radish containing natural iodine. The steps of the method are as follows: 1) Soak the radish seeds with 1% potassium permanganate solution, rinse them repeatedly with tap water, and sow them directly in the field; 2) apply enough base fertilizer before the radish seeds are sown in the field, or use solid iodine organic Apply the fertilizer to the soil surface at one time, or spray liquid iodine fertilizer on the leaves 4 to 6 times before harvesting the radish. Topdressing with compound fertilizer 1-2 times during this period. The invention can not only directly cultivate radishes containing natural iodine, but more importantly, can increase the background content of iodine in the soil and the surrounding environment, thereby improving the ecological environment where iodine is deficient, and iodine-containing radishes can be directly used as a natural source of iodine supplementation for the human body Therefore, iodine-containing radish leaves can be used as a natural iodine-supplementing feed for poultry and livestock, and ultimately increase the iodine content level in the entire food chain.

Description

technical field [0001] The invention relates to a cultivation method of radish containing natural iodine. 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 thyroid gland. There must be 3 or more in each molecule of thyroid gland. 4 iodine atoms, without iodine, the thyroid gland cannot synthesize thyroxine. Thyroxine has biological functions such as promoting protein synthesis, activating more than 100 enzymes, regulating energy conversion, accelerating growth and development, and maintaining the structure of the central nervous system. Therefore, the human body Iodine deficiency can lead to a series of physiological disorders and abnormal biological functions, such as goiter and cretinism, especially iodine deficiency during growth and development of infants, which can cause intellectu...

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. Studies have shown that thyroid cancer is also related to excessive intake of iodine. People of different ages and categories (such as children, adults, Pregnant women and breast-feeding mothers) have very different iodine requirements every day. When iodine supplementation is implemented for people who are really deficient in iodine, people who are not deficient in iodine and even a few people who take too much iodine should be supplemented with iodine forcibly. According to relevant data, the incidence of hyperiodine disease has increased due to excessive iodine intake in China in recent years, and it is spreading; third, in areas with severe iodine deficiency, once iodized salt is stopped, the prevalence of IDD will increase. will increase, which shows that salt iodization is a temporary rather than a long-term measure to fundamentally improve the iodine deficiency situation
