Method for planting carrot containing iodine

Abstract

The invention discloses a planting method of carrot containing iodine. The method comprises the following steps: 1) high yielding and quality carrot seeds are selected, seta is removed from the seeds by kneading, then the seeds are dipped in mild water for accelerating germination and sowed when the seeds steep to germination; 2) ridges are started to be made, then 10-20 percent of germinated carrot feeds are evenly mixed with fine soil and sowed in lines, then the seeds are watered sufficiently and covered with soil evenly, ensuring that no seed exposes out of the soil; 3) thinning is made before final singling of seedlings to remove over close, weak, inferior and disease seedlings; 4) sufficient basic fertilizer is fertilized and solid iodine organic fertilizer is added to the surface of the soil in a lump before the carrot seeds are sowed in the field, or liquid iodine fertilizer is sprayed by stages before harvest, and cultivation and weeding as well as prevention and curing of plant diseases and insect pests are well done. The carrot containing iodine planted by the invention can not only replenish nutrition, which is good for physical health, but also can be an effective natural source of iodine for human body through food.

Description

technical field [0001] The invention relates to a method for planting iodine-containing carrots. 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 intellectual disabi...

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, Pregnant women and breast-feeding mothers) have great differences in iodine requirements every day (Table 1). When iodine supplementation is implemented for people who are really deficient in iodine, people who are not deficient in iodine or 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
