Method for cultivating celery containing iodine

Abstract

The invention discloses a cultivation method of iodine-enriched celery. The steps of the method are as follows: 1) Soak the celery seeds in clear water, clean them, wrap them in cotton cloth and shake them loose, and germinate them at a temperature of 5-10° C.; Fertilize, crush, and level, pour enough water, and spray 50% carbendazim solution for disinfection. After the celery seeds that have accelerated the germination are evenly spread on the seedbed soil, after the seedlings emerge, sprinkle a little sieved fine wet soil to cover the young sprouts , and then make the black shading net into a small shed for shading; 3) When the celery seedlings have 5 to 6 true leaves, transplant the seedlings; After crushing, apply enough base fertilizer, apply solid iodine organic fertilizer to the soil surface at one time, and topdress with organic fertilizer and compound fertilizer 1 or 2 times. The invention can directly cultivate iodine-rich celery, increase the background content of iodine in the soil and the surrounding environment, improve the ecological environment in iodine-deficient areas and increase the iodine content level in the food chain.

Description

technical field [0001] The invention relates to a cultivation method of iodine-enriched celery. 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 t...

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
