Method for planting mustard containing iodine

Abstract

The invention discloses a cultivation method of iodine-containing mustard mustard. The method comprises the following steps: 1) selecting high-quality, high-yield, and disease-resistant pickled mustard seeds, sowing them on the seedbed, and covering them with a layer of plant ash or fine sand after sowing; Thinning, the seedling distance is 3-4 cm, and the second seedling is carried out when the 3rd to 4 true leaves appear, and the seedling distance is 6-7 cm; 3) When the seedling age is 30-35 days, the seedling has 5-6 true leaves 4) Before the seedlings are planted, apply enough basal fertilizer, and apply solid iodine organic fertilizer at one time, or spray liquid iodine fertilizer in stages before harvesting. The iodine-containing pickled mustard cultivated by the invention can be directly used as a natural source of iodine supplementation for the human body by eating, and the residual iodine fertilizer can increase the background content of iodine in the soil and surrounding environment, thereby gradually improving the ecological environment in iodine-deficient areas.

Description

technical field [0001] The invention relates to a cultivation method of iodine-containing mustard mustard. Background technique [0002] Iodine is an essential trace element for 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 4 iodine atoms in each molecule of thyroid gland. Without iodine, the thyroid gland cannot synthesize thyroxine, which can promote protein synthesis. , activate more than 100 enzymes, regulate energy conversion, accelerate growth and development, maintain the structure of the central nervous system and other biological functions, so iodine deficiency in the human body will lead to a series of physiological disorders and abnormal biological functions, especially iodine deficiency in infants during growth and development , can cause intellectual disability, and this kind is called as " iodine deficiency disease " (IDD) because of the overall influence that iodine deficiency cause...

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. Studies have shown that thyroid cancer is also related to excessive intake of iodine. People of different ages and categories, such as children, adults, The daily iodine requirements of pregnant women and lactating mothers are very different (Table 1). When iodine supplementation is implemented for the people who are really iodine deficient, it is also necessary to give iodine supplements to those who are not deficient in iodine, and even a small number of people who have excessive iodine intake 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 incidence of IDD will increase. The prevalence rate will rise, which shows that salt iodization is a temporary, rather than a long-term measure that fundamentally improves the iodine deficiency situation
